What is the Labcorp test no. for an MTHFR Gene Mutation Analysis test?

Labcorp test no. 511238. On a Labcorp requisition the test is printed as "MTHFR Gene Mutation Analysis", billing code CPT 81291. If you are holding a doctor's order, that is the line to look for; a TestWell requisition carries the same code.

Can I walk into Labcorp for an MTHFR Gene Mutation Analysis test without a doctor?

Yes, with a requisition. Labcorp patient service centers draw what a requisition orders; they do not write orders. You can get one from your doctor, or order through TestWell ($95.99 + $6 fee), where a licensed physician in our network authorizes the order and the Labcorp requisition arrives by email, usually within minutes. Labcorp OnDemand does not list this test, so TestWell is the self-ordered route at Labcorp. New York and New Jersey do not allow self-ordered draws at Quest or Labcorp; TestWell orders from those states route to BioReference instead.

Do I need an appointment at Labcorp?

Most Labcorp patient service centers take walk-ins, and an appointment on Labcorp's site shortens the wait. Bring a photo ID and the emailed requisition (on your phone is fine). No fasting is required for this test. No fasting or special preparation required.

How long do Labcorp MTHFR Gene Mutation Analysis results take?

Results post to your TestWell portal in 5–7 business days after the draw, with reference ranges and the option to share them with your clinician. Labcorp runs the sample in its own CLIA-certified laboratory whichever way it was ordered, so the result and the turnaround are the same as a doctor-ordered MTHFR Gene Mutation Analysis test.

Is an MTHFR Gene Mutation Analysis test cheaper at Labcorp or Quest Diagnostics?

Through TestWell this test is drawn at Labcorp only ($95.99 + $6 fee); it is not offered at Quest Diagnostics. Labcorp OnDemand does not list it for consumers.

Can I buy an MTHFR Gene Mutation Analysis test on Labcorp OnDemand?

Not as of our last catalog match (Nov 8, 2026) — Labcorp OnDemand did not list the MTHFR Gene Mutation Analysis test among the tests it sells to consumers. A doctor's order or a TestWell order ($95.99 + $6 fee) are the routes, and both are drawn at the same Labcorp patient service centers and run in the same Labcorp laboratory under test no. 511238.

MTHFR Gene Mutation Analysis at Labcorp: test code, price, and how to order

Labcorp OnDemand, Labcorp's own consumer site, does not sell the MTHFR Gene Mutation Analysis test (we last matched its catalog on Nov 8, 2026), so there is no walk-up consumer price at Labcorp itself. Two routes get it drawn there: a doctor's order, billed to insurance or at the lab's self-pay rate, or TestWell — $95.99 plus one $6 lab processing fee, $101.99 all-in for one test — where a licensed physician authorizes the order and the Labcorp requisition arrives by email. The collection, the Labcorp laboratory and the result are the same either way.
