ApoE Alzheimer's Risk at Labcorp: test code, price, and how to order
Labcorp OnDemand, Labcorp's own consumer site, does not sell the ApoE Alzheimer's Risk 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 — $184.99 plus one $6 lab processing fee, $190.99 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 ApoE Alzheimer's Risk 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. 125536 if you want the same test.
- Through TestWell. $184.99 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 5–7 business days. Add tests to the same draw without another fee.
Labcorp OnDemand, Labcorp's own consumer ordering site, did not list the ApoE Alzheimer's Risk 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.
How to walk into Labcorp with a TestWell order
- Add the ApoE Alzheimer's Risk test to your cart, choose Labcorp at checkout, and pay — a physician authorizes the order, usually within minutes.
- Open the emailed requisition on your phone (or print it) and bring a photo ID.

Frequently asked questions
- How much is an ApoE Alzheimer's Risk test at Labcorp?
- Labcorp OnDemand, Labcorp's own consumer site, does not sell the ApoE Alzheimer's Risk 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 — $184.99 plus one $6 lab processing fee, $190.99 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 ApoE Alzheimer's Risk test?
- Labcorp test no. 125536. On a Labcorp requisition the test is printed as "APOE Alzheimer's Disease Risk". 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 ApoE Alzheimer's Risk 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 ($184.99 + $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 ApoE Alzheimer's Risk 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 ApoE Alzheimer's Risk test.
- Is an ApoE Alzheimer's Risk test cheaper at Labcorp or Quest Diagnostics?
- Through TestWell this test is drawn at Labcorp only ($184.99 + $6 fee); it is not offered at Quest Diagnostics. Labcorp OnDemand does not list it for consumers.
- Can I buy an ApoE Alzheimer's Risk test on Labcorp OnDemand?
- Not as of our last catalog match (Sep 12, 2026) — Labcorp OnDemand did not list the ApoE Alzheimer's Risk test among the tests it sells to consumers. A doctor's order or a TestWell order ($184.99 + $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. 125536.
