The short answer
A charge from FUNCTION HEALTH* 100 TESTS represents an annual $499 membership covering 100+ comprehensive whole-body laboratory biomarker tests through Quest Diagnostics.
What is Function Health?
A statement entry showing FUNCTION HEALTH* 100 TESTS indicates a payment processed by Function Health Inc. for its direct-to-consumer health tracking platform. Unlike individual test kits ordered from services like Everlywell, a Function Health Annual Membership provides two rounds of clinical blood testing per year covering more than 100 biological markers, including cardiovascular metrics, hormone levels, thyroid function, metabolic health, and autoimmune indicators. Blood draws are fulfilled through partner Quest Diagnostics patient service centers nationwide, with results reviewed by licensed clinicians and delivered through a digital member portal.
This charge appears as an upfront $499 payment when you register for the service, or as an automatic renewal billed exactly twelve months after your original sign-up date. Because a full year passes between payments, cardholders often overlook that the membership renews on an annual billing schedule. You might also notice charges for optional specialty add-ons, such as multi-cancer early detection testing or advanced epigenetic biological age scoring, which are billed to your payment card on file upon ordering.
If you see FUNCTION HEALTH* 100 TESTS on your credit card or bank record, check whether you or someone in your household scheduled lab testing through functionhealth.com. Function Health offers a refund within 30 days of purchase provided you have not yet completed your blood draw at a lab facility. You can manage your subscription and disable auto-renew directly within your online member account. You can also download detailed itemized receipts for HSA or FSA reimbursement.
