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 IV4Health.

Function Health

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

IV4Health

Labs, medication fulfillment, consults, or shipping may sit outside the headline price.

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.

IV4Health pros and cons

Official FAQ gives a concrete public IV price range instead of hiding all pricing behind a form.

Adds a true local clinic comparator for IV-only pages.

Useful contrast against membership-heavy or telehealth-led providers.

Narrower service breadth than multi-category longevity brands.

1What is included in the base membership price versus billed additionally?
