SiPhox Health vs Function Health

No appointments, lines, needles, or phlebotomists—just a 5-minute at-home test for key healthspan and longevity biomarkers. Instead of testing biomarkers with little health insight or those that rarely change, we focus on the most important ones—delivering the same health insights with lower cost and minimal blood draw.
