What does Function test?

Membership includes access to 100+ lab tests for all major biological functions, plus on-demand access to re-testing.

Lipoprotein (a)

About 50% of people who suffer heart attacks have a normal cholesterol level. Considering this, many cardiologists believe Lp(a) to be the major driver of cardiac events. This invaluable test is used by specialists, but not yet widely adopted in primary care. Lp(a) is a risk marker, particularly for those with symptoms or with a family history of cardiovascular disease. Lipoprotein are made of lipids (fats) and proteins (energy), and are referred to as "sticky proteins."

Apolipoprotein B (Apo B)

ApoB helps transport lipids throughout the bloodstream, which is vital in the health of your cardiovascular function. Along with other lipid tests, ApoB is a powerful risk marker for cardiovascular disease.

Lipoprotein Fractionation

Lipoprotein fractionation measures the number and size of lipoprotein particles. When comparing this test with others in your lipid panel, it helps examine personal risk for coronary artery disease. It is also helpful for those with a family history of heart attack or stroke, those taking cholesterol medication, or if someone has had a cardiac event with normal cholesterol levels.

Low-density lipoprotein (LDL) Cholesterol

This test is a risk marker for cardiovascular diseases. LDL is responsible for carrying cholesterol to cells. But, despite its good intentions, LDL is known as the “bad” cholesterol because when levels are too high, it can cause the formation of plaque buildup in the arteries.

Triglycerides

The ratio of your triglycerides to HDL measures your risk for heart disease. Triglycerides are the most common type of fat in the body that stores excess energy from your diet. An accumulation of triglycerides means there is too much fat in your blood and higher risk of a cardiac event.

High-density lipoprotein (HDL) Cholesterol

HDL is part of your comprehensive lipid panel, an essential risk assessment for heart disease. There are two types of cholesterol: high-density lipoprotein (HDL) and low-density lipoprotein LDL. Think of the H as healthy, helpful, heart-supporting cholesterol that helps reduce plaque buildup.

Total Cholesterol

Your total cholesterol numbers are part of a risk assessment for heart disease. Too much cholesterol in the blood can damage arteries and blood vessels and elevate risk for stroke, heart attack, and heart disease. Cholesterol is a fatty substance produced by the liver to help thousands of bodily functions, such as building cells, promoting hormone and brain function, and synthesizing Vitamin D.

Triiodothyronine (T3) Free

T3 levels can reveal overactive (hyperthyroidism) or underactive (hypothyroidism or Hashimoto’s) thyroid. T3 is the most powerful thyroid hormone in your body. It helps regulate body temperature, control heart rate, lower your cholesterol, improve your memory, promote regrowth after hair loss, soothe muscle aches, regulate bowel movements, and fertility.

Thyroxine (T4) Free

This test is typically cross-referenced with TSH and T3 to gain insight into your overall thyroid function. Thyroxine, or T4, is produced in the thyroid then released into the bloodstream where it travels to the liver and kidneys. It is converted to the hormone triiodothyronine (T3). The synergy of T4 and T3 is important for your heart and digestive function, metabolism, brain development, bone health, and muscle control.

Thyroid stimulating hormone (TSH)

About 1 in 5 women and 1 in 10 men have hypothyroidism, and a TSH test can help reveal thyroid issues like if it is overactive (hyperthyroidism or Grave’s disease) or underactive (hypothyroidism or Hashimoto’s). TSH is made from the pituitary gland and controls the release of thyroid hormones: triiodothyronine (T3) and thyroxine (T4).

Thyroid Peroxidase (TPO)

This test checks for elevated antibodies attacking your TPO, which can detect thyroid-related autoimmune disorders: Hashimoto’s (underactive thyroid or hypothyroidism) or Graves’ disease (overactive or hyperthyroidism). The thyroid peroxidase (TPO) is an enzyme that helps produce hormones.

Thyroglobulin Antibodies (TgAb)

Detects thyroid-related autoimmune disorders: Hashimoto’s (underactive thyroid or hypothyroidism) or Graves’ disease (overactive or hyperthyroidism). TgAb attack your thyroglobulin, a protein produced and used by the thyroid gland to make T3 and T4 hormones, both of which control your metabolism and tissue/cell growth.

Antinuclear Antibodies (ANA)

An ANA test assists in detecting autoimmune disorders. ANAs are an autoantibody produced by the immune system. While healthy antibodies protect the body from pathogens like viruses and bacteria, autoantibodies cause disease by mistakenly attacking healthy cells and tissues.

Rheumatoid Arthritis Factor (RF)

RFs are antibodies produced by your immune system, and presence of RFs indicates autoimmune disorders, like rheumatoid arthritis, rheumatoid vasculitis, or Sjögren’s syndrome. Asymptomatic individuals with elevated RF in their blood may have pre-autoimmunity.

Celiac Disease

Approximately 20% of people with celiac disease, an autoimmune disorder triggered by gluten, are asymptomatic. However, even without symptoms, untreated celiac disease may chip away at your immune system, which can lead to Type I diabetes, multiple sclerosis, anemia, osteoporosis (due to issues with nutrient absorption), and skin conditions.

Test available on demand, not included in membership.

Anti-Mullerian Hormone (AMH)

AMH is a key fertility marker that assesses your ovarian reserve (egg count) at the time of taking the test. This shows your body’s potential of producing eggs for fertilization, if you're nearing menopause, and if you’re experiencing a hormonal condition such as polycystic ovary syndrome (PCOS) and primary ovarian insufficiency (POI).

Testosterone, Total

In all adults, healthy levels of testosterone are important for general health, body composition, sexual function, and reduced risk of disease. Function tests both "free" and “total” testosterone in your blood. You will naturally have a higher level of “total” than “free” because together abnormal levels signal issues with your SHBG production or hypothalamus or pituitary gland, or if you have hypogonadism.

Testosterone, Free

This helps evaluate functions associated with testosterone levels, such as fertility, sexual function, muscle mass, energy, mood, insulin resistance/sensitivity, and pituitary function. It can also detect prediabetes, PCOS, or menopause. Function tests both "free" and “total” testosterone in your blood.

Prolactin

Prolactin levels can guide diagnosis of irregular or absent menstrual periods, infertility, menopausal symptoms, osteoporosis, liver or kidney disease, hypothyroidism, and/or estrogen and testosterone deficiency, in addition to unwanted lactation. It is also a screen for pituitary tumors. Prolactin is a peptide hormone produced by your pituitary gland and stimulates breast development and milk production in pregnant women.

Sex Hormone Binding Globulin (SHBG)

When your SHBG levels change, it can impact the amount of available hormones in your body, either too much or too little. This can affect your menstrual cycle as well as fertility. SHBG patrols the amount of sex hormones your body tissues can use.

DHEA-S

DHEA-S checks in on your adrenal glands, screens for adrenal tumors or cancers, and helps determine the cause of masculine physical characteristics (virilization) in girls and women. DHEA-S is one of three adrenal androgens: steroid hormones that control the development and maintenance of masculine characteristics.

Estradiol

For biological females, testing the hormone estradiol (one type of estrogen) is key in detecting menopause, polycystic ovarian syndrome (PCOS), androgen- or estrogen-producing tumors, uterine and breast cancer, and mitigating risk of osteoporosis and cardiovascular disease.

If you're on hormonal birth control, this test will not be run.

Luteinizing Hormone (LH)

LH levels gives insight into your sexual development and fertility. LH releases estrogen during the menstrual cycle, which triggers the release of an egg from the ovary; otherwise known as ovulation. It can also help determine states of perimenopause and menopause.

If you're on hormonal birth control, this test will not be run.

Follicle-Stimulating Hormone (FSH)

FSH evaluates ovarian health and pituitary function, and can help determine a diagnosis of polycystic ovary syndrome (PCOS), perimenopause, or menopause. As a type of protein hormone, FSH is responsible for stimulating the ovarian follicles that produce and release eggs during ovulation.

If you're on hormonal birth control, this test will not be run.

hCG: Pregnancy Test

A positive beta human chorionic gonadotropin (hCG) level is used for early detection of pregnancy. Pregnancy tests detect the hCG hormone in the blood and urine.

Test available on demand, not included in membership.

IGF-1

IGF-1 is known as the "growth hormone" because it stimulates growth in cells throughout the body. This leads to growth and development (from the womb and through adolescence), strengthening of tissues (e.g. improving bone density, building muscle), and healing (e.g. skin, bones, gut lining), depending on what the body needs.

Test available on demand, not included in membership.

Prostate Specific Antigen (PSA), Free

PSA tests screen for tumors and/or monitor pre-existing prostate cancer. PSA is a protein created in the prostate, a small gland that produces a fluid for semen.

Prostate Specific Antigen (PSA), Total

PSA illuminates the health of your prostate and acts as a signal if something is wrong. Your "total" and "free" PSA screens for tumors and/or monitors pre-existing prostate cancer. PSA is a protein created in the prostate, a small gland that produces a fluid for semen.

Testosterone, Free

This helps evaluate functions associated with testosterone levels, such as fertility, sexual function, muscle mass, energy, mood, insulin resistance/sensitivity, and pituitary function. It can also screen for prediabetes. Function tests both "free" and “total” testosterone in your blood.

Testosterone, Total

In all adults, healthy levels of testosterone are important for general health, body composition, sexual function, and reduced risk of disease. Function tests both "free" and “total” testosterone in your blood. You will naturally have a higher level of "total" than "free.” If both are abnormal, it may signal issues with your SHBG production or hypothalamus or pituitary gland, or if you have hypogonadism.

Luteinizing Hormone (LH)

LH helps the testicles make testosterone, which is important for producing sperm and many other male functions. LH levels gives insight into your sexual development and fertility.

Follicle-Stimulating Hormone (FSH)

FSH levels share insight into your fertility, along with testicle and pituitary health. Strong levels are necessary for healthy male hormonal function, and are partially responsible for sperm production and sexual development.

Estradiol

For biological males, testing the hormone estradiol (one type of estrogen) is key in understanding testosterone levels and sexual function. Estradiol is essential in sexual development and managing the reproductive system.

DHEA-S

DHEA-S can gauge the health of your reproductive system and adrenal glands. It is one of three adrenal androgens: steroid hormones that control the development and maintenance of masculine characteristics.

Sex Hormone Binding Globulin (SHBG)

When your SHBG levels change, it can impact the amount of available hormones in your body, either too much or too little.This can affect sexual function and fertility. SHBG patrols the amount of sex hormones your body tissues can use.

Prolactin

Prolactin levels can guide diagnosis of low libido or erectile dysfunction, or screen for pituitary tumor. Prolactin is a peptide hormone produced by your pituitary gland.

IGF-1

IGF-1 is known as the "growth hormone" because it stimulates growth in cells throughout the body. This leads to growth and development (from the womb and through adolescence), strengthening of tissues (e.g. improving bone density, building muscle), and healing (e.g. skin, bones, gut lining), depending on what the body needs.

Test available on demand, not included in membership.

Glucose

Too much glucose (hyperglycemia) is major driver of all disease and illness: cancer, diabetes, high blood pressure, heart attacks, kidney disease, Alzheimer’s disease. Glucose is a type of sugar (from food) that your body uses for energy. But, sometimes rather than being absorbed and used, it forms glycogen and enters fat cells in the liver. Overtime, this will cause a decline in your overall health.

Hemoglobin A1c (HbA1c)

HbA1c is the average amount of glucose attached to blood cells over the last 90 days. It diagnoses, monitors, and screens for prediabetes and diabetes. This test is a revelatory look into your health, specifically your body’s ability to control your blood sugar. Unhealthy levels are triggered by inflammation, vitamin deficiencies, kidney damage, thyroid disorders, and more. Your diet and habits can have a substantial impact on this test.

Insulin

Insulin levels can uncover reasons behind abnormal blood sugar, insulin resistance, and more. It can also reveal hidden blood sugar issues even years before they escalate to something like diabetes. Establishing your insulin's baseline is incredibly insightful to how your habits and lifestyle affect your health.

Adiponectin

Adiponectin abnormalities are an indicator of metabolic disorders, such as obesity, Type 2 diabetes and heart disease. Adiponectin is a growth hormone, like prolactin and insulin, that influences body weight and metabolism by combating inflammation, regulating glucose, metabolizing lipids, and controlling insulin response.

Leptin

Leptin tells your brain when to stop eating. It is a hormone created by fat cells that regulates energy expenditure, and this test is an important diagnostic tool for leptin deficiency, which causes obesity and chronic inflammation. High levels are often associated with vascular risk factors, including insulin resistance, diabetes mellitus, hypertriglyceridemia, and hypertension.

Homocysteine

A homocysteine test checks on your body’s Vitamin B levels and methylation function, a key biochemical process essential for almost all of your body’s systems. Abnormal homocysteine can build up and increase your risk of blood clots, dementia, osteoporosis, heart disease, heart attack, and stroke. Homocysteine is an amino acid that helps organs grow and regenerate.

Uric Acid, Serum

Uric acid in the blood screens for metabolic disorders, like gout, anemia, and immunodeficiencies. This often overlooked test has renewed attention after recent studies show elevated levels can increase the risk of death from cardiovascular issues by 39% and stroke by 35%.

Total Protein

Protein levels explore the health of your kidneys, liver, and absorption processes. The human body is made up of thousands of proteins, all of which have various roles in making and maintaining every cell in your body, including enzymes and hormones. Proteins also fuel those cells and your immune system with energy.

Albumin

Abnormal albumin can indicate malnutrition, liver or kidney disease, or a digestive inflammatory condition (Crohn’s or Celiac) resulting in malabsorption. Albumin is a protein made by your liver that helps fluid remain in the bloodstream rather than leaking into other tissues. It also helps hormones, vitamins, and enzymes transfer throughout the body to their final destinations.

Total Bilirubin

In tandem with a full liver panel, this test can help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia, or blockage of the bile ducts. The liver makes bile to help you digest food, and bile contains bilirubin. A healthy liver can get rid of bilirubin, but when the liver isn't working properly it isn't able to breakdown bilirubin and dispose of it.

Aspartate Aminotransferase (AST)

AST is an enzyme mostly found in the liver and metabolizes amino acids. Testing for AST in your blood can help detect liver damage from injury or a number of diseases and conditions, like hepatitis, cirrhosis, mononucleosis, or other liver diseases, heart problems, or pancreatitis.

Alanine Aminotransferase (ALT)

ALT levels look into the health of your liver, and this test may be able to detect liver disease, jaundice, or cirrhosis. ALT is an enzyme in the liver that helps convert proteins into energy. If your liver cells are damaged from excess alcohol, drugs, disease, or injury, ALT shows up in the bloodstream and hence in a blood test.

Alkaline Phosphatase (ALP)

ALP can help detect and/or monitor conditions related to your liver, malnutrition, an autoimmune disorder, or bone disease. ALP is an enzyme that breaks down proteins. It is found throughout the entire body, but mostly prevalent in the liver, bones, intestines, and kidneys.

Sodium

Sodium looks at your electrolytes and pH. When sodium levels are abnormal it can signal issues with the brain, lungs, liver, heart, kidneys, thyroid, and adrenal glands. Sodium is an electrolyte and mineral that maintains balance between water and electrolytes in your body. Consider it a conductor of your blood pressure, muscles, and nerves.

Creatinine

Creatinine levels vary from person to person, but abnormalities typically signal kidney disease or damage. Your creatinine is directly related to lifestyle, diet, medication, and how those can impact your kidneys’ ability to function. Creatinine (not to be confused with creatine) is a chemical compound left over from everyday wear and tear of your muscles.

Blood Urea Nitrogen

Urea nitrogen is a waste product your kidneys flush out, but the presence or buildup of urea nitrogen waste in your blood means your kidneys aren't regulating waste properly. Compared with your creatinine levels, this test can screen for kidney disease.

Mercury

Mercury is a neurotoxin that can result in kidney damage, brain damage and fertility issues. It is everywhere: fish, coal, plastics, pesticides, mercury amalgam dental fillings, and more. In 2022, the US government reaffirmed regulations to curtail mercury pollution from power plants. Testing your mercury levels over time and establishing a baseline for yourself gives you an understanding of why and how you're being exposed to mercury.

Lead

Lead is a common element all around us and is naturally absorbed, but it can be dangerous if you're exposed to hazardous sources. Untreated toxicity can lead to fertility complications, kidney failure, convulsions, cardiovascular issues, hormonal disruption, gastrointestinal issues, and neurological changes.

Arsenic

Arsenic is a neurotoxin that can lead to hypertension, infertility, neurological disorders, and peripheral neuropathy (pain in the hands and feet). Arsenic comes in two forms: organic and inorganic used in manufacturing and mining. Arsenic can be found in seafood, wine, groundwater and more.

Test available on demand, not included in membership.

Aluminum

The form of aluminum that causes harm is present in many everyday household and personal care products. An aluminum test detects whether or not you’ve been overexposed to aluminum. Too much impairs iron absorption and can lead to faulty hematopoiesis--the process through which the body makes red blood cells.

Test available on demand, not included in membership.

ABO

Know your blood type! This information is important, not only in case of an emergency where you might need a blood transfusion but also if you want to donate blood to help others. Blood type is also a predictor for some conditions that occur during pregnancy and/or if you are susceptible to blood clotting or kidney stones.

Red Blood Cell

RBC count can reveal various anemias, vitamin deficiencies, colon, bladder, or kidney issues, chronic disease that cause bone marrow suppression, autoimmune disorders, blood disorders, polycythemia vera, congenital heart disease, and more.

Hemoglobin

Hemoglobin reflects the number of red blood cells active in your blood. Low levels may uncover anemia, vitamin deficiencies, loss of blood (both internal and external), and chronic diseases. The test can also help detect diseases affecting the lungs, liver, kidneys, or cardiovascular system, significant long-term infection, cognitive impairment, and certain types of cancer and diagnose chronic blood disorders.

Hematocrit

As part of your complete blood count, an HCT test measures the percentage of red blood cells in your blood. This test helps screen for, diagnose, and monitor conditions that affect your blood or bone marrow.

Mean Cell Volume (MCV)

MCV's insight into your blood is a unique indicator of your overall health. If MCV is either high or low overtime (most likely indicating a chronic vitamin deficiency or blood condition), it can degrade your body's general wellness and thus your phenotypic age. MCV measures average size of red blood cells: whether they are too big, too small, or just right.

Mean Cell Hemoglobin (MCH)

MCH is usually done as part of your complete blood count and can help detect various types of anemia (deficiency in iron, B12, or folate), blood loss, cancer, kidney or liver disease, autoimmunity. MCH measures the average amount of hemoglobin in your red blood cells.

Mean Corpuscular Hemoglobin Concentration (MCHC)

MCHC measures the amount of hemoglobin per unit volume. So, this test assesses the hemoglobin content with the volume of the cell, which can uncover iron-deficiency anemia, hypothyroidism, spherocytosis or RBC agglutination.

Red Cell Dist Width (RDW)

RDW is the size and volume of your red blood cells. RDW and MCV explore your overall health, and together, they can detect liver disease and various types of vitamin-deficiency anemias even before symptoms occur. When either or both are abnormal overtime, it can lead to higher risk of disease and increase your phenotypic age.

Platelet Count

Abnormal platelet count is a risk marker for heart attack, stroke, and other heart disease, but this test can also help diagnose autoimmune disease, bone marrow damage (which can be caused by certain cancers, such as Leukemia and/or cancer treatments), spleen disorder, parasites). Platelets, which are made in the bone marrow, are small, colorless blood cells that form clots with the goal to stop or prevent bleeding.

Mean Platelet Volume

Mean Platelet Volume (MPV) measures the mass of platelets, which is important in determining the cause of thrombocytopenia (a low platelet count) or thrombocytosis (a high platelet count). So, why does MPV matter? When platelets are healthy, there is a dynamic relationship between their size and count.

High-sensitivity C-reactive protein (hs-CRP)

hs-CRP is revelatory in your overall health as it relates to your risk of inflammation-related disease. Chronic inflammation is linked to every major disease: heart disease (even before symptoms occur), type 2 diabetes, cancer, diabetes, high blood pressure, Alzheimer’s, depression, all autoimmune diseases, and severe allergic reactions, like asthma.

Cortisol

Cortisol levels provide insight into your adrenal, pituitary, and thyroid function. They can also help diagnose Cushing’s disease and see if a preexisting autoimmune disease is causing chronic inflammation. As a stress hormone, cortisol helps regulate many bodily functions including stress response, blood sugar, blood pressure, inflammation, metabolism, and so much more.

White Blood Cell

WBC are a core part of your immune system. A healthy WBC baseline overtime means your body is fit to fight off disease or other hazards that threaten your body. When abnormal for long periods, this can impact your biological age negatively by impairing healing and increasing your risk of illness.

Basophils

Basophils account for only around 1% of white blood cells, but play a role in allergy defense and stimulating antibodies against pathogens and parasitic organisms (ticks and worms) that cause injury/infection.

Eosinophils

Eosinophils are called to inflamed areas of the body to trap substances, kill infected cells, viruses, parasites, and bacteria, and help tame an allergic response. Testing can reveal issues in the digestive tract, specifically the esophagus. (% and Absolute)

Neutrophils

Testing the quantity of neutrophils helps detect damage caused by inflammatory disorders (rheumatoid arthritis, gout), infection (acute or chronic), certain cancers (myelocytic leukemia), and physical stressors (eclampsia in pregnant women, injury, burns). Neutrophils are the patrollers and first responders in the immune system that attack all antigens in their path. Includes both percent and absolute levels.

Lymphocytes

Lymphocyte levels can reveal a number of conditions, including autoimmunity, bone marrow disorders, kidney disease, gastrointestinal disorders, and more. The role of lymphocytes in your body’s immune defense is so important that abnormal levels can weaken your body and lead to severe illness and/or your body’s inability to fight off danger. Includes both percent and absolute levels.

Monocytes

Like other WBCs, monocytes help the immune system destroy invaders. But, they also facilitate healing and repair. Abnormal levels can indicate bacterial infection, virus or fungus, stress, chronic infection, or an autoimmune disorder. Includes both percent and absolute levels.

Lyme

Lyme disease can go undetected (and therefore untreated) for years after initial infection. Testing for Lyme is incredibly important because it can eventually lead to brain and nerve damage. Lyme disease is most common tick-borne illness in North America, is difficult to diagnose because its symptoms--more than 100 of them--can mimic other conditions like the flu, multiple sclerosis, lupus, arthritis and even Alzheimer's.

Test available on demand, not included in membership.

Omega 3 and Omega 6

Imbalanced omega-3 and omega-6 is a risk factor for cardiovascular disease, aged-related macular degeneration, rheumatoid arthritis, cancer, and more. Omegas are essential fatty acids (EFAs), which are the building blocks for every cell in your body. Well-balanced omegas can contribute to optimal brain performance, mental health, nerve function, a healthy heart, circulation, immune system, gastrointestinal tract, skin, hair and nails.

Methylmalonic Acid (MMA)

MMA measures Vitamin B12 and can detect a deficiency even when mild or just beginning. MMA is a key component for metabolism and energy, and because your blood and/or urine levels of MMA rise when your B12 levels drop, it is a more sensitive biomarker than testing just your B12 levels.

Iron

Healthy iron levels create vitality throughout your entire body. Iron helps various vital functions, like providing energy and focus, building a strong gastrointestinal tract and immune system, and regulating body temperature. Iron deficiency can lead to numerous biological problems, including anemia.

TIBC

TIBC assesses your body’s ability to transport iron in the blood, and can diagnose and/or monitor iron-deficiency or iron overload. Lower than normal levels of TIBC could indicate too much iron and a variety of conditions, including anemias, inflammation, or liver disease.

Ferritin

Your ferritin levels can help diagnose iron deficiency, liver disease, inflammation, or insulin resistance. Ferritin is a protein that stores iron in cells and then releases the iron when your body makes more red blood cells.

Vitamin D, 25-Hydroxy

Vitamin D deficiency is widely underdiagnosed and undertreated. Over time, low levels can lead to hypothyroidism, osteoporosis, cancer, heart disease, fatigue, depression, seasonal affective disorder (SAD), gut issues, and fibromyalgia. The role of vitamin D is vast and benefits the immune system, thyroid, bones and teeth, muscles, and brain.

Calcium

Calcium levels help understand symptoms related to your kidneys, bones, thyroid, parathyroid, or nerves. Calcium is a mineral your body uses to build and maintain strong bones, teeth, muscle control, and blood circulation.

Zinc

Zinc is mostly known for its immune support, but it's actually a powerful mineral across all systems of the body: from strengthening bones and muscle, preventing blood clotting and metal accumulation, promoting proper insulin and thyroid function, and so much more. If deficient, it can impact your mood, sexual function, and immunity.

Magnesium

Magnesium is a mineral imperative for cells to make energy, for chemical pumps to work and stabilize membranes, and to help muscles relax. Low magnesium can impact calcium, potassium, phosphorus, and/or parathyroid hormone. This test helps evaluate your absorption, and help determine whether or not there’s a problem with your kidney function or gastrointestinal tract.

Copper

Healthy copper levels are important because it is a vital mineral that helps your body metabolize iron, make and regenerate melanin, bones, and connective tissues, among other essential processes. However, untreated copper toxicity can become hazardous to the heart, kidneys, liver, and brain.

Test available on demand, not included in membership.

Iodine

Iodine levels give you insight into your thyroid health.The thyroid gland absorbs iodine to produce T4 and T3 hormones, to prevent goiters and help the body make protein and use oxygen.

Test available on demand, not included in membership.

Selenium

Selenium looks into the health of your liver, thyroid hormones, and kidneys. Selenium is a trace mineral found in soil that helps your body produce the antioxidant glutathione, which alleviates oxidative stress. It also stimulates thyroid hormones the aid in heart and digestive function, metabolism, brain and bone health, and muscle control.

Test available on demand, not included in membership.

pH

The goal of testing pH is to identify whether or not you have an acid-base imbalance, to determine how severe the imbalance is, and to help diagnose underlying diseases or conditions (such as diabetic ketoacidosis, a life-threatening complication of diabetes). Testing also helps monitor critical illnesses that affect acid-base balance, such as chronic lung disease and kidney disease.

Specific Gravity

Specific Gravity is the concentration of your urine, which is a quick way to tell if your kidneys are trying to compensate for an abnormality. This test helps convey your overall kidney health and can screen for renal tubular necrosis, diabetes insipidus, kidney failure, low levels of sodium in the blood, or a severe kidney infection.

Glucose

If you're healthy, glucose levels in your urine are generally too low to be detected. Glucose in your urine, or glucosuria, is a symptom of both type 1 diabetes and type 2 diabetes (your blood sugars are high), if you're a pregnant woman, or if you have liver abnormalities or hormonal disorders.

Protein

The goal of this test is evaluating kidney function. Normally, protein stays in your blood and doesn't pass into urine. Your kidneys prevent this from happening. If proteinuria (protein in urine) is detected, the kidneys aren't functioning properly.

Bilirubin

Look into the general health of your liver. When healthy, your liver makes bile, which contains bilirubin. This bile helps digest food, and a thriving liver gets rid of excess bilirubin, but when the liver isn't working properly bilirubin builds up.

Ketone

Ketone testing can help diagnose ketoacidosis or diabetic ketoacidosis (DKA), a complication of diabetes; or issues unrelated to diabetes like gastrointestinal diseases (IBS, Colitis, Crohn’s, Celiac, GERD). Ketones are produced in the liver as part of your body’s metabolism process. If you're low on glucose, your body burns fat for energy instead and produces ketones, which show up in urine. This is the process behind ketogenic (keto) diets.

Nitrite

Increased nitrites in urine can indicate an infection in the urinary tract: anywhere from kidneys, renal pelvis, ureters, bladder, and urethra. Healthy urine has chemicals called nitrates. When bacteria enters the urinary tract, nitrates can transform into nitrites.

Leukocytes

Leukocytes are white blood cells (WBCs), which are vital to health! However, if they're detected in your urine, it may be a sign of inflammation in the urinary tract or kidneys.

Occult Blood

This test detects blood in your urine, which could potentially indicate a urinary tract infection (UTI). enlarged prostate, kidney damage (from injury), kidney disease, or other kidney or bladder-related conditions.

Clarity

The clarity of your urine, from clear to turbid, explores the health of your kidneys and urinary tract.

Color

An unusual urine color can be a sign of disease, such as a kidney disorder or urinary tract infection (UTI). The scale of light to dark gives a picture of how much water is being flushed through your system.

Bacteria

Healthy urine is sterile, so when bacteria is present, it's a sign of infection, especially if you experience symptoms.

Hyaline Casts

It's ok if hyaline casts show up in urine. However, large amounts of them may indicate kidney damage due to decreased blood flow to the kidneys.

Squamous Epithelial Cells

It's normal to have a small amount of epithelial cells in your urine. A large amount, however, may indicate an infection, kidney disease, or another serious medical condition.

Amylase

Amylase checks in on your pancreas, and irregular levels can detect salivary disease, celiac disease, IBD, and growth of a tumor in an amylase producing tissue. Amylase is an enzyme produced in the salivary glands and pancreas. It’s a digestive protein that breaks down carbohydrates and starches into the simple sugars. This gives your body energy.

Lipase

A lipase test is able to show swelling or inflammation in the pancreas, a condition known as pancreatitis. It can also reveal other health conditions such as kidney disease, pancreatic cancer, and problems with the gallbladder or esophagus. Lipase is an enzyme produced by the pancreas that helps the body digest fats.

Chloride

A chloride test is useful in diagnosing the underlying causes of abnormal fluid levels or pH balances, such as dehydration, kidney disease, liver disease, heart failure, high blood pressure, or other disorders. Chloride is a major mineral in your body that manufactures channels in cell membranes, which carry out different vital tasks.

Bicarbonate

Bicarbonate levels monitor pH and/or electrolyte balance. When irregular, it can be a sign of dehydration, kidney disease, liver disease, heart failure, high blood pressure, or other disorders. Bicarbonate is an alkali of the electrolyte family. As an alkali, it plays a role in balancing the acid-base of your pH balance.

Potassium

Potassium levels can detect kidney disease, liver disease, heart failure, high blood pressure, or other disorders. As an electrolyte, potassium helps muscles contract, digestion, nerves transport messages from brain to the body, and balance fluids and regulate blood pressure.

Blood Pressure

Establishing a healthy baseline for you blood pressure can reduce your risk hypertension, which can lead to heart disease and stroke. Prolonged blood pressure caused by smoking, obesity, and chronic stress can cause a traffic jam in your arteries. Over time this can lead to serious, life-threatening medical conditions.

ApoE is a predictive genetic biomarker for Alzheimer’s disease, currently one of the leading causes of death in the United States. The result of this test illuminates your personal risk, even decades before onset of the disease. Holding this wisdom in your hands, along with the health of your brain's support systems (many of which are part of your Function biomarkers), can potentially help you avert onset completely.
