What is the Labcorp test no. for a PT and PTT test?

Labcorp test no. 020321. On a Labcorp requisition the test is printed as "PT and PTT (Prothrombin & Partial Thromboplastin Time)", billing code CPT 85610, 85730. 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 PT and PTT 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 ($26.99 + $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.

Results post to your TestWell portal in 1–3 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 PT and PTT test.

Is a PT and PTT test cheaper at Labcorp or Quest Diagnostics?
