The Test Grade. The Reason Behind It.

Potentially useful for the right buyer, with meaningful evidence, coverage, transparency, access, cost, terms, or privacy tradeoffs to review.

A lower grade does not mean a panel is a bad personal fit. Your Fit Score can be higher when its purpose, price, sample, access, or support matches what you need.

Important limits and omissions

  • Product-specific assay methods, analytical performance, and the complete laboratory credential chain were not recovered for this record.

No broader panel in the Labbrary catalog lists every biomarker on this one for a lower listed price.

Counted among one-time lab-draw listings with a published price, matched by published biomarker names. That doesn’t mean the tests are equivalent. Updated October 1, 2026.

The full breakdown

Eight Dimensions.
One Named Result.

Open any row for the reasoning and evidence behind the named result.

The current pricing page states a $365 annual membership, repeat testing cadence, and exclusions for add-on tests and imaging.

The current first-party library publishes 119 distinct included measurements across the major membership categories and separately identifies optional add-ons, establishing a strong and auditable scope with bounded omissions.

The current workflow states that clinicians review results, surface what matters, and provide personalized protocol guidance, while medical interpretation remains outside the service.

The current evidence identifies blood and urine testing, 119 named included measurements, and a national laboratory collection workflow, but assay methods, analytical performance, and the complete laboratory credential chain remain incomplete.

The current FAQ states access through more than 2,000 Quest locations across 48 states, with additional visit rules for some members and states.

Function's current privacy policy expressly applies to Function members and addresses consumer health data, use, sharing, research, retention, deletion, and consumer controls, while laboratory sample retention and some third-party handling details remain outside the membership policy.

The current membership pages describe broad preventive monitoring across heart, hormones, thyroid, nutrients, toxins, inflammation, liver, kidneys, and electrolytes.

The current pages disclose the membership price, testing cadence, complete named included inventory, laboratory collection surface, and the boundary that Function is not a medical provider, while method and performance details remain incomplete.

Reading the labels

What Has Been Checked?

Source collected

Evidence labels stay separate from the Test Grade. They show how much source support exists for the evaluation.

The balance

The Strengths. The Tradeoffs.

Strengths

  • The current pricing page states a $365 annual membership.
  • The current workflow and FAQ describe recurring testing, clinician review, and more than 2,000 Quest locations across 48 states.

Watch-outs

  • Membership is not a substitute for medical care or health insurance.
  • Function states it does not itself collect, store, analyze, or retain blood samples. Independent laboratories govern blood sample handling and retention.
  • Function retains personal information while an account or service relationship is active and may retain it afterwards for operational, legal, accounting, reporting, fraud prevention, or claims needs.
  • Function lists BPA, PFAS, environmental allergy, and mold and environmental response biomarker groups as optional member add-ons. They cost extra and are not included in the $365 membership price. Exact add-on prices and availability must be confirmed in the member account.
