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.
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.
Blood health testing evaluates your blood cells, clotting factors, and oxygen-carrying capacity to detect anemia, infection, bleeding disorders, and other hematologic conditions.
Anyone investigating unexplained fatigue, frequent infections, bruising, or as part of a routine health check.

A PT and PTT (Prothrombin & Partial Thromboplastin Time) test costs $54.99 at TestWell — $60.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $150.00 self-pay for the same test, and often more.
