Iron & TIBC at Quest Diagnostics: test code, price, and how to order
Quest Health, Quest Diagnostics's own consumer site, does not sell the Iron & TIBC test (we last matched its catalog on Sep 12, 2026), so there is no walk-up consumer price at Quest Diagnostics itself. Two routes get it drawn there: a doctor's order, billed to insurance or at the lab's self-pay rate, or TestWell — $25.99 plus one $6 lab processing fee, $31.99 all-in for one test — where a licensed physician authorizes the order and the Quest Diagnostics requisition arrives by email. The collection, the Quest Diagnostics laboratory and the result are the same either way.

We re-match Quest Health's catalog periodically; if the lab starts selling this test direct, its price will appear here.

Two ways to get an Iron & TIBC test at Quest Diagnostics
- With a doctor's order. Your clinician sends a requisition to Quest Diagnostics; the lab bills your insurance and your share depends on your plan and deductible. Ask for the Quest Diagnostics test code 5616 if you want the same test.
- Through TestWell. $25.99 plus one $6 fee per order. A licensed physician in our network authorizes the order, the Quest Diagnostics requisition arrives by email (usually within minutes), you walk into any Quest Diagnostics patient service center, and results post to your portal in 1–3 business days. Add tests to the same draw without another fee.
Quest Health, Quest Diagnostics's own consumer ordering site, did not list the Iron & TIBC 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 Quest Diagnostics with a TestWell order
- Add the Iron & TIBC test to your cart, choose Quest Diagnostics 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.
- Walk into any Quest Diagnostics patient service center — fasting, so book a morning slot; most take walk-ins, and an appointment on Quest Diagnostics's site shortens the wait.

In New York or New Jersey? Neither Quest nor Labcorp takes self-ordered draws there; TestWell routes those orders to BioReference automatically.

Frequently asked questions
- How much is an Iron & TIBC test at Quest Diagnostics?
- Quest Health, Quest Diagnostics's own consumer site, does not sell the Iron & TIBC test (we last matched its catalog on Sep 12, 2026), so there is no walk-up consumer price at Quest Diagnostics itself. Two routes get it drawn there: a doctor's order, billed to insurance or at the lab's self-pay rate, or TestWell — $25.99 plus one $6 lab processing fee, $31.99 all-in for one test — where a licensed physician authorizes the order and the Quest Diagnostics requisition arrives by email. The collection, the Quest Diagnostics laboratory and the result are the same either way.
- What is the Quest Diagnostics test code for an Iron & TIBC test?
- Quest Diagnostics test code 5616. On a Quest Diagnostics requisition the test is printed as "Iron, TIBC and Ferritin Panel", billing code CPT 83540, 83550. 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 Quest Diagnostics for an Iron & TIBC test without a doctor?
- Yes, with a requisition. Quest Diagnostics patient service centers draw what a requisition orders; they do not write orders. You can get one from your doctor, or order through TestWell ($25.99 + $6 fee), where a licensed physician in our network authorizes the order and the Quest Diagnostics requisition arrives by email, usually within minutes. Quest Health does not list this test, so TestWell is the self-ordered route at Quest Diagnostics. 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 Quest Diagnostics?
- Most Quest Diagnostics patient service centers take walk-ins, and an appointment on Quest Diagnostics's site shortens the wait. Bring a photo ID and the emailed requisition (on your phone is fine). This test is run on a fasting sample — fast for 8–12 hours (water is fine) and book a morning slot. Fasting for 8–12 hours recommended. Best drawn in the morning. Stop iron supplements 24 hours before.
- How long do Quest Diagnostics Iron & TIBC 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. Quest Diagnostics 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 Iron & TIBC test.
- Is an Iron & TIBC test cheaper at Quest Diagnostics or Labcorp?
- Through TestWell the price is the same $25.99 at either lab — pick the location that is convenient; the requisition is written for the lab you choose. Neither Quest Health nor Labcorp OnDemand lists this test for consumers, so TestWell's price is the self-ordered price at both labs.
- Can I buy an Iron & TIBC test on Quest Health?
- Not as of our last catalog match (Sep 12, 2026) — Quest Health did not list the Iron & TIBC test among the tests it sells to consumers. A doctor's order or a TestWell order ($25.99 + $6 fee) are the routes, and both are drawn at the same Quest Diagnostics patient service centers and run in the same Quest Diagnostics laboratory under test code 5616.
