Quest Health

1. What it measures 25% of the rating 4 of 5

   The Elite Health Profile lists 85+ markers including ApoB, hs-CRP, insulin, HbA1c, TSH, T3 and T4, testosterone, vitamin D, ferritin, B12 and folate; Lp(a) is a separate $45 test, and we found no IgG food panels.

2. Lab quality 20% of the rating 5 of 5

   Quest runs the tests itself, and CMS lists its Clifton, NJ and West Hills, CA labs as CAP-accredited, though Quest does not say which lab handles your sample.

3. Results & follow-up 20% of the rating 4 of 5

   Quest says results are released after a clinical review (3 to 5 business days), a healthcare coordinator calls if values fall outside expected ranges, and a consult with an independent provider is included.

4. Your data 20% of the rating 3 of 5

   Quest Consumer says it does not sell personal or consumer health data, but its notices allow sharing for targeted advertising and the lab’s HIPAA notice lets it use de-identified data for any lawful purpose; a 2019 vendor breach reached about 11.9 million patients.

5. Value 15% of the rating 3 of 5

   The Elite profile works out to about $4.80 a marker plus the $6 fee, cheaper than Labcorp’s panel but about twice Mito or Function per marker, and ApoB is sold only inside a $215 panel.

The rating, 3.9 of 5, is the weighted average of these scores. See how we rank lab & biomarker tests and our standard.

• Paid certification College of American Pathologists, as recorded in the CMS CLIA database February 2025

  CMS lists Quest’s Clifton, NJ lab (CLIA 31D0696246) and West Hills, CA lab (05D0642827) as accredited by CAP, both from 2025-02-28 to 2027-02-27. Labs pay for CAP inspections, which check lab procedures, not how accurate this service’s results are. Open ↗ (opens in a new tab)

Has Quest lost patients’ data?

Twice, as reported. In 2019 its billing vendor AMCA was hacked and Quest put the number at about 11.9 million patients; it said no lab results were exposed because it does not send them to AMCA (Trend Micro, 2019 (opens in a new tab)). Earlier, a 2016 attack exposed names, birth dates and test results, including HIV status, of 34,000 patients, and Quest paid $195,000 to settle (TechTarget, 2020 (opens in a new tab)). We could not confirm how the lawsuits over the AMCA breach ended.

Does Quest sell or share my health data?

Quest Consumer’s notice (opens in a new tab) says it does not sell consumer health data but may share it with Quest Diagnostics and service providers for analytics and “more personalized messaging”, and its privacy notice (opens in a new tab) allows sharing for targeted advertising with an opt-out. The lab’s HIPAA notice (opens in a new tab) says de-identified data may be used for any lawful purpose, and Quest’s pharma page (opens in a new tab) sells drug makers “Commercial Alerts” on lab orders, described as de-identified. We could not tell whether Quest Health orders feed them. A class action, Cole v. Quest Diagnostics, alleged that a pixel on Quest’s websites collected visitors’ activity for advertising; a federal judge dismissed it in January 2025 on a point of law (the party exception in California’s wiretap statute) (Inside Class Actions (opens in a new tab)).

Do broad health tests like these help healthy people?

Not shown. A Cochrane review (opens in a new tab) of 17 trials of general health checks (251,891 participants in the 15 that reported outcomes) found little or no effect on deaths. Use single tests for a question, such as a family history of heart disease.

What is the company-made health score?

The Comprehensive and Elite profiles add a “Health Quotient Score” from 1 to 100 that Quest built from your labs, family history and habits. We found no outside evaluation of it, so treat it as a summary, not a measure.

Is it promoted by influencers or sold through paid partners?

Yes, through an affiliate program. Quest’s affiliate page (opens in a new tab) says affiliates earn on each lab test sold, through the Impact network. We did not find which creators take part, so a Quest Health recommendation online may be a paid one.

Has anyone tested it independently?

We found no published independent test of the accuracy of Quest Health results. CAP accreditation is paid for by the lab and checks its procedures.

• The lab can be checked. CMS’s CLIA database lists Quest labs in Clifton, NJ (CLIA 31D0696246) and West Hills, CA (05D0642827) as CAP-accredited, and on 2026-10-23 it listed 217 active labs with Quest Diagnostics in the name. Quest does not say which site will run your sample.
• A clinician group reviews the order and the results. Quest says PWNHealth and its affiliated entities review each purchase before it goes to the lab, results are released after a clinical review, and a healthcare coordinator calls if values fall outside expected ranges. A consult with an independent provider is included.
• Prices are posted per test (seen 2026-10-23): Lp(a) $45, lipid panel $59, HbA1c $39, vitamin D $75, plus the $6 physician service fee shown on each page. The Elite Health Profile is $399 for 85+ markers.
• Quest Consumer’s notices say it does not sell personal information or consumer health data (health data notice updated 2025-07-31), and they describe how to ask for deletion.
• We searched its catalog for IgG food-sensitivity panels, which the AAAAI advises against, and found only IgE allergy panels, celiac antibody tests and IgG antibody tests for infections.

• The $6 physician service fee is added to each test price, is non-refundable and is shown per product. We did not test whether it repeats for each test in a cart. Cancelling before the draw costs a non-refundable $20 per order ($45 for a home collection kit). ApoB is sold only inside the $215 Advanced Heart Health panel, which also holds Lp(a) and Lp-PLA2; Labcorp OnDemand and Ulta Lab Tests sell ApoB alone.
• The site and the lab are covered by different notices. Quest Consumer says it does not provide HIPAA-covered services; the lab, Quest Diagnostics, is, and its notice bars selling your health information without your authorization but lets it use de-identified data for any lawful purpose. The site shares browsing data with ad partners unless you opt out.
• Memberships cost less per marker. Mito Health and Function Health offer 110 to 140 markers for about $200 to $365. Quest’s Elite profile is a one-time test with no retest built in.
• A single result is a snapshot. The Elite profile adds a company-made health score, and a $29 “biological age” add-on from Humanity is offered with it; we did not review either. Sample collection is not offered in AZ, HI or PR, according to each test page we read. Quest does not bill insurance for tests bought here, and the terms include binding arbitration and a class-action waiver.
• Rechecked 2026-11-05: profile prices are unchanged: Basic $199 (59+ markers), Comprehensive $329 (75+) and Elite $399 (85+), each with a physician service fee starting at $6. There is no membership and no built-in retest.
