What is the Labcorp test no. for a Vitamin B6 test?

Labcorp test no. 004655. On a Labcorp requisition the test is printed as "Vitamin B6 (Pyridoxine)", billing code CPT 84207. 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 a Vitamin B6 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 ($51.99 + $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 required. If taking B6 supplements, note the dosage for your provider.

How long do Labcorp Vitamin B6 results take?

Results post to your TestWell portal in 3–5 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 Vitamin B6 test.

Is a Vitamin B6 test cheaper at Labcorp or Quest Diagnostics?

Through TestWell the price is the same $51.99 at either lab — pick the location that is convenient; the requisition is written for the lab you choose. Neither Labcorp OnDemand nor Quest Health lists this test for consumers, so TestWell's price is the self-ordered price at both labs.
