PT w/INR
Prothrombin Time (PT) measures how long it takes for blood plasma to clot, assessing the function of the extrinsic and common pathways of the coagulation cascade (factors I, II, V, VII, X). It is used to screen for bleeding abnormalities, assess liver function, and monitor warfarin therapy (often reported as INR). Prolonged PT indicates slower clotting.

Clinical Notes
PT with INR evaluates the extrinsic coagulation pathway. INR standardizes PT ratios for warfarin monitoring and coagulopathy severity assessment.
