Function Health vs SiPhox Health

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.

Official site clearly positions SiPhox Health around wellness labs 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.
