At TestWell it costs $54.99 plus a $6 lab fee, needs no fasting, and results post in 1–3 business days. Physician-authorized with no doctor's visit or insurance needed; draw at Labcorp. **Ordering for surgical clearance? Allow 6–8 days before your procedure.** Results typically post 1–3 business days after your blood draw — but between visiting the lab, weekend processing, and your surgical team's review, we recommend ordering at least 6–8 days ahead of surgery. An order placed the day before a procedure will not have results back in time. ## Key facts | Fact | Value | | --- | --- | | Price | $54.99 + $6 lab processing fee per order ($60.99 all-in for this test alone) | | CPT code | 85610, 85730 | | Sample | Blood draw | | Fasting | Not required | | Results | 1–3 business days | | Labs | Labcorp | | Biomarkers measured | 3 | | Physician authorization | Included — no doctor's visit, referral or insurance needed | | Payment | Card, HSA or FSA; cash-pay only (no insurance billing) | ## What does the PT and PTT (Prothrombin & Partial Thromboplastin Time) test tell you? Measures both clotting pathways — PT evaluates the extrinsic pathway, PTT evaluates the intrinsic pathway. This combined panel measures both Prothrombin Time (PT) and Partial Thromboplastin Time (PTT), providing a complete assessment of your blood's clotting ability. PT measures the extrinsic clotting pathway and is commonly used to monitor Warfarin therapy, while PTT measures the intrinsic pathway and is used to monitor Heparin therapy and screen for clotting factor deficiencies. Together, they give a comprehensive picture of coagulation function. This test is essential for pre-surgical clearances, monitoring anticoagulant therapy, investigating unexplained bleeding or bruising, and evaluating clotting disorders like hemophilia or von Willebrand disease. **Clinical use:** Blood health testing evaluates your blood cells, clotting factors, and oxygen-carrying capacity to detect anemia, infection, bleeding disorders, and other hematologic conditions. ## Who should order it? Anyone investigating unexplained fatigue, frequent infections, bruising, or as part of a routine health check. ## Biomarkers measured - [Prothrombin Time (PT)](https://www.test-well.com/biomarkers/prothrombin-time) - [INR](https://www.test-well.com/biomarkers/inr) - [Partial Thromboplastin Time (PTT)](https://www.test-well.com/biomarkers/activated-partial-thromboplastin-time-aptt) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Labcorp | $54.99 | $60.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.
