Prothrombin time (PT) IVD, control

Prothrombin time (PT) IVD controls are materials used to verify the performance of assays that measure the prothrombin time in clinical specimens, sometimes standardized to the international normalized ratio (INR). These controls help ensure the accuracy and reliability of coagulation testing in medical laboratories.

These control materials are typically supplied as reference samples with known values that laboratories use to validate their testing procedures. They are essential quality assurance tools for monitoring the performance of PT testing systems, though specific regulatory classifications may vary by jurisdiction.
