27 paź 2020 · Prothrombin time (PT) is the most common way to express the clotting capacity of blood. PT results are reported as the number of seconds the blood takes to clot when mixed with a thromboplastin reagent.
21 lis 2019 · Normal values include the following [1] : The reference range for prothrombin time is 11.0-12.5 seconds; 85%-100% (although the normal range depends on reagents used for PT) Full...
