The starting prices buy different things. Compare included collection, existing results and responsibility for follow-up.
Function Health is convenient for bundled laboratory access, but its value depends on useful follow-up rather than the size of its panel.
Readers seeking bundled testing access who also have a plan for clinical follow-up.
Broad panel size does not establish screening benefit; current price pages include an expired-offer footnote.
Explore Function HealthRead full reviewInsideTracker is the better fit for organizing blood results you already have; its $149 membership should never be mistaken for an included testing package.

Membership alone is not an included comprehensive blood panel or replacement for clinical care.
Explore InsideTracker MembershipRead full reviewFunction describes a membership arranging broad laboratory testing with written clinician review. InsideTracker's base membership provides a platform for organizing data, including uploaded blood results, while blood-test purchases are separate. Comparing their headline membership prices as if both include the same panel would obscure the main buying distinction.
Start with what you already have. If appropriate laboratory results are available through your clinician, the useful gap may be organization. If access to a particular test is the problem, determine whether a bundle actually includes it and whether you need the rest of the panel.
InsideTracker lists its base membership at $149 annually with annual renewal. That is not a complete testing total. Function pages display $365 but also include first-year language and a promotion footnote that expired October 8, 2026. We therefore leave Function's current checkout and renewal amounts unconfirmed rather than presenting a definitive price winner.
For either service, obtain an itemized quote that distinguishes membership, specimen collection, laboratory analysis, optional home draws and add-ons. If a result needs confirmation or outside care, ask which costs fall outside the package. Access to discounted imaging is not the same as included imaging.
A long test list can be convenient but should not be the sole reason to enroll. Check whether the result will change a decision, which population supports the screening approach and who explains uncertainty. An optimization target in a dashboard should be distinguished from a laboratory reference interval or a diagnostic threshold.
A personal clinician can help identify duplication and decide whether an unexpected finding requires confirmation. A service's written explanation may be useful without constituting complete ongoing care. Ask explicitly who handles urgent findings, medication questions and specialist referrals.
Function's described offer has state limitations and a mid-year testing component; confirm eligibility and which markers repeat. InsideTracker's membership can be canceled to stop renewal, but its published policy treats membership refunds differently from unused test refunds. Review the rules for each component before purchasing a bundle.
These practical questions often determine value more than a polished sample report. Timing, travel to a collection site and the ability to share original results with your clinician should fit your routine.
InsideTracker is worth considering if the principal need is consolidating compatible existing data. Function may fit a reader seeking bundled access who understands its screening limits and obtains a clear current quote. Neither is automatically necessary because you are interested in healthy aging.
Our preventive-panel guide explains why more tests do not guarantee better health outcomes. Choose a service around a defined gap and a follow-up pathway, then reassess whether it continues to answer that question at renewal. Keep the complete quote and original test reports so renewal is a decision you can judge against what the service actually added.
Services can differ in products, eligibility, care and payment commitments. Compare matching offers before interpreting a headline price as a saving.
