ALT (Alanine Aminotransferase) at Labcorp: test code, price, and how to order
Labcorp OnDemand, Labcorp's own consumer site, does not sell the ALT test (we last matched its catalog on Sep 12, 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 — $18.99 plus one $6 lab processing fee, $24.99 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.

Labcorp OnDemand does not list this test, so the TestWell price is the self-ordered price at Labcorp; a doctor-ordered draw is billed through insurance or at the lab's self-pay rate. We re-match Labcorp OnDemand's catalog periodically; if the lab starts selling this test direct, its price will appear here.
Two ways to get an ALT test at Labcorp
- With a doctor's order. Your clinician sends a requisition to Labcorp; the lab bills your insurance and your share depends on your plan and deductible. Ask for the Labcorp test no. 001545 if you want the same test.
- Through TestWell. $18.99 plus one $6 fee per order. A licensed physician in our network authorizes the order, the Labcorp requisition arrives by email (usually within minutes), you walk into any Labcorp patient service center, and results post to your portal in 1–3 business days. Add tests to the same draw without another fee.
Labcorp OnDemand, Labcorp's own consumer ordering site, did not list the ALT test when we last matched its catalog (Sep 12, 2026) — so there is no “buy it on the lab's site” route for this test.

Frequently asked questions
- How much is an ALT test at Labcorp?
- Labcorp OnDemand, Labcorp's own consumer site, does not sell the ALT test (we last matched its catalog on Sep 12, 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 — $18.99 plus one $6 lab processing fee, $24.99 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.
- What is the Labcorp test no. for an ALT test?
- Labcorp test no. 001545. On a Labcorp requisition the test is printed as "ALT (SGPT)", billing code CPT 84460. 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 ALT 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 ($18.99 + $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. Avoid alcohol and strenuous exercise for 24 hours before.
- How long do Labcorp ALT results take?
- 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 ALT test.
- Is an ALT test cheaper at Labcorp or Quest Diagnostics?
- Through TestWell the price is the same $18.99 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.
- Can I buy an ALT test on Labcorp OnDemand?
- Not as of our last catalog match (Sep 12, 2026) — Labcorp OnDemand did not list the ALT test among the tests it sells to consumers. A doctor's order or a TestWell order ($18.99 + $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. 001545.
