About Function Health
Function is an annual testing membership: you give blood and urine samples at a partner lab, then repeat a smaller panel midway through the year. Your account brings together results, trends and written clinician notes; a routine review call is not included.

Google PlayWhat people praise
Broad testing for the price
Members value getting a wide range of lab tests together, especially when they compare the membership cost with arranging individual tests themselves.
Results that are easier to understand
Reviewers appreciate explanations alongside their lab numbers, helping them understand what stands out rather than working through a list of results on their own.
Straightforward lab appointments
Members describe easy scheduling and convenient partner-lab visits, with the ordering and blood-draw process requiring little effort on their part.
A useful picture over time
Members value comparing results across testing rounds and keeping their health information together, giving them more to discuss with their own doctor.
What people complain about
Getting through to a person
Some members describe repeated exchanges with automated support without reaching someone who can resolve a missing result, account issue or specific testing question.
Advice can feel generic
Some reviewers find the guidance too general and want someone to connect the findings to their individual situation and explain which next steps matter most.
Incomplete or delayed results
Members report occasions when results arrive late or an expected test is missing, leaving them to chase answers or arrange additional follow-up.
Sharing results takes extra work
Some members find it cumbersome to download a complete set of results or share them with their doctor in a useful format.
Stories

A rising PSA trend prompts further testing
Tanner’s PSA rose across three years of Function testing, prompting him to push for a urology referral and biopsy. At 35, he was diagnosed with prostate cancer, underwent surgery and reported a good physical recovery.

An iron result leads to treatment

An added hormone test helps explain subtle changes
Catherine added an IGF-1 test to her Function membership and found a markedly high result. Specialist follow-up uncovered a pituitary tumor; after surgery, she reported improvements in her hormone and blood-sugar results.
