Once you join Function, you can log in to schedule your Annual round of testing.
An average lab visit takes 15 to 30 minutes, provided you are on time. Your first set of tests each year may require two lab visits to complete.
Your annual Function test looks at over 100 biomarkers, from heart and hormones to liver and heavy metals. Usually, only 35 mL of blood is drawn at one time, which is why your set of tests may be split into two lab visits. For context, a blood donation is 14 times more at approximately 500 mL.
Pro tip: Being extra hydrated improves blood flow and may make your blood test quicker. We encourage you to book your two lab visits within the same week for consistency in your results.

No. The large number of tests included with your Function membership would not work via self-collect, at-home kits. We explored using these mail-in kits for single tests but concluded that they would be too unreliable due to ongoing issues with improper finger pricks and adherence to instructions, which could interfere with specimen integrity, specimen size, temperature control, ambient particle exposure, time delay, and human tissue damage.
