About Prothrombin Test: Prothrombin Time PT with INR in El Centro
Prothrombin time (PT) with INR is a laboratory test that assesses the extrinsic and common pathways of the coagulation cascade.
The PT measures the time in seconds for plasma to clot after the addition of tissue factor and calcium. Because PT results vary between laboratories due to differences in reagents and instrumentation, the INR was developed to standardize results. The INR is calculated by comparing the patient's PT to a normal control plasma, raised to the power of the international sensitivity index (ISI) of the thromboplastin reagent used.
This test is frequently used to monitor warfarin therapy, as the INR provides a consistent target range across laboratories. It is also part of the initial evaluation of unexplained bleeding or bruising, and it can be ordered alongside the activated partial thromboplastin time (aPTT) to assess different parts of the clotting process. In liver disease, PT and INR may be prolonged because the liver synthesizes clotting factors.
Results are typically reported as PT in seconds, INR, and sometimes aPTT if included in the panel. Turnaround time is generally one to three business days. Preparation instructions should be followed as provided by the laboratory.
