This panel measures how long it takes your blood to clot using three related tests: prothrombin time, INR, and partial thromboplastin time. This overview covers what the Prothrombin Time measures and how its results are reported.

What the Prothrombin Time Screens For

A result outside the range is a signal to follow up with a healthcare provider, not a diagnosis by itself. Because the Prothrombin Time looks at a defined set of markers, it screens a specific area rather than every possible condition. The Prothrombin Time is often used to check a particular set of markers when there is a reason to look more closely. Screening results from the Prothrombin Time are most useful when reviewed alongside your history by a healthcare provider.

Accuracy and Limitations of the Prothrombin Time

The Prothrombin Time is run by a licensed laboratory, and like any test it has limitations. A result from the Prothrombin Time reflects the sample at the time it was collected and does not capture every factor. The accuracy of the Prothrombin Time depends on proper sample collection and on the laboratory method used. A value outside the range is not a diagnosis on its own, so the Prothrombin Time is best interpreted with a provider.

How Often the Prothrombin Time Is Repeated

For routine monitoring, the Prothrombin Time may be repeated at regular intervals to track the same markers over time. If a result from the Prothrombin Time is outside the range, a provider may suggest repeating it sooner. This panel measures how long it takes your blood to clot using three related tests: prothrombin time, INR, and partial thromboplastin time. Comparing one Prothrombin Time report with the next is easier when the same laboratory method is used.
