Hidden fees to watch for

Published starting prices rarely include all costs. These are the most common fee gaps buyers miss when comparing Function Health and Performance Optimal Health.

Function Health

Medication changes, shipping, or higher treatment tiers may still change the final bill.

Performance Optimal Health

Medication changes, shipping, or premium tiers may still change the final bill.

Lab monitoring (both)

Most telehealth programs do not include lab work in the monthly fee. Expect $75–$150 per panel, required 2–4× per year for any hormone or TRT program.

Initiation and intake fees

Some providers charge a one-time intake fee ($50–$199) on top of the first monthly payment. This is not always visible on the pricing page.

Function Health pros and cons

100+ biomarker panels offer diagnostic depth that far exceeds what most primary care or standard wellness labs include.

Annual membership pricing makes comprehensive testing more cost-effective than ordering individual panels through traditional labs.

Physician review is included, giving members clinical context rather than raw numbers without interpretation.

Function Health does not prescribe or deliver therapies — it is a diagnostic platform, not a treatment provider.

Performance Optimal Health pros and cons

Official site clearly positions Performance Optimal Health around trt, hrt and broader longevity support.

Telehealth availability makes it easier to compare remote-care convenience against clinic-led alternatives.

Lab or diagnostics integration makes the total care model easier to compare than a headline price alone.

Some final pricing still depends on consult review, location, or service customization.

Function Health: Function Health does not prescribe or deliver therapies — it is a diagnostic platform, not a treatment provider.

Performance Optimal Health: Some final pricing still depends on consult review, location, or service customization.

Questions to ask before choosing

These are specific to Wellness Labs programs — the primary service overlap between Function Health and Performance Optimal Health.

1Is a physician order required, or can I order panels directly?
2Are results reviewed with a clinician, or returned raw with no interpretation?
3What is the cost per panel, and is a membership or bundle more cost-effective?
4Can I use insurance or my HSA/FSA to pay for any of these tests?

Which should you choose?
