How much does a PT/INR test cost in 2026?
A Prothrombin Time with INR test costs $23.99 at TestWell — $29.99 all-in, since the $6 lab processing fee is charged once per order and there is no draw or physician fee. The labs' own sites list the same test at $42.00 at Quest Health and $39.00 at Labcorp OnDemand (checked Oct 10, 2026). Hospital outpatient labs typically bill around $120.00 self-pay. With insurance you pay your plan's negotiated rate against your deductible; TestWell's price is fixed before the draw and HSA/FSA-eligible.

What the $23.99 includes
- Authorization of the order by a licensed physician in TestWell's network — no office visit or referral.
- The lab requisition, emailed within minutes, accepted at any Quest or Labcorp patient service center.
- The blood draw and the lab work itself (CPT 85610) — 2 markers: Prothrombin Time, INR.
- Results in your TestWell portal in 1–3 business days, with reference ranges and the option to share them with your clinician.
- One $6 lab processing fee per order — charged once, not per test, so a PT/INR test alone is $29.99 and adding tests to the same order adds only their sticker prices.
Why PT/INR prices vary so much
The same PT/INR test, run on the same analyzer, can be billed at four different prices. Ordered through a hospital or clinic and billed to insurance, the charge is set by the facility's chargemaster and your plan's negotiated rate, then filtered through your deductible — the typical self-pay hospital figure is in the table above. Ordered from the lab's own consumer site, you pay the lab's retail list price. Ordered through a direct-to-consumer service like TestWell, you pay a negotiated volume rate plus the service's margin and fee.
When you compare services, add the fees before you compare: some list a low sticker price and add a draw fee and a physician fee at checkout, typically $18–$28 per order. TestWell's only addition is the $6 processing fee, once per order.
