About Prothrombin Test: Prothrombin Time PT with INR in Berkeley
Prothrombin time measures the seconds required for plasma to clot after adding tissue factor and calcium. The INR standardizes that result across different reagent lots and laboratories.
The PT pathway involves factors VII, X, V, II (prothrombin), and fibrinogen. A prolonged PT can reflect deficiencies or inhibitors in any of these components, vitamin K deficiency, or liver dysfunction.
The INR is calculated by raising the PT ratio to the power of the international sensitivity index of the thromboplastin reagent. This correction allows results from different laboratories to be compared meaningfully, which is essential for monitoring vitamin K antagonist therapy.
Because the test is sensitive to both pre-analytical and analytical variables, proper specimen collection and timely processing matter. Results are typically interpreted alongside the activated partial thromboplastin time, platelet count, and clinical context.
