This is the most comprehensive lab testing I have ever had. I am thrilled to know more about my health and how to improve it.

Best money I have spent on healthcare.

Function blows my mind. The UI, UX, price and clinician notes are all phenomenal.

Many illnesses and leading causes of death can be prevented or delayed with lifestyle changes.
Lifestyle factors:
  • Can reduce the risk of cardiovascular disease by over 80%
  • Can reduce the risk of diabetes by over 90%
  • Are attributed to 40% of dementia cases
  • Are attributed to 42% of cancer cases
Preventive care matters:
But preventive care under insurance misses the mark — bloodwork at an average annual physical doesn’t test for 80+ important markers.
Illness is expensive. Even with insurance coverage, co-pays and non-covered services add up.
Treatment costs might look like:
  • Treating diabetes can cost $12,022 per year out of pocket
  • Heart failure costs an average of $4,423 per year out of pocket
  • The average hospital stay in the U.S. costs $2,529 per day out of pocket
the bottom line:
Testing can save you thousands in future health costs.

Real people. Real results.
