There’s more to your cholesterol than you realize

Routine cholesterol tests haven’t changed since the 1950s—but the science has.

The truth behind “normal” cholesterol

Routine cholesterol tests haven’t changed since the 1950s—but the science has. The basic panel (LDL, HDL, triglycerides) only measures cholesterol by weight, but we now know that particle quality and number are more telling indicators of health. Function tests a range of biomarkers that measure cholesterol and overall heart health, to help you better understand your risk for cardiovascular disease.

  • Go beyond basic cholesterol testing: Routine cholesterol tests (LDL, HDL, triglycerides) only measure cholesterol by weight, but testing LDL particle number and size is essential for assessing risk of cardiovascular disease.
  • Get advanced heart insights: Your cholesterol impacts your heart health. So, Function goes deeper and tests particle number and size, plus other critical biomarkers like Lipoprotein(a) and Apolipoprotein B (ApoB) for a more accurate risk assessment.
  • Stay ahead of your health: Heart disease rarely develops overnight. Advanced cholesterol testing helps you better understand your risk, so you can take proactive steps to protect your heart.
