PT quality controls are used for performance checks of the Coaguchek Plus, Biotrack, and Coumatrak Protime coagulation systems. PT controls are used to verify the reliability of sample measurement and to indicate possible system performance problems. These controls are available in two levels. Level 1 produces a prothrombin time similar to that of a healthy coumarin-free individual. Level 2, deficient in clotting factors, gives a prolonged prothrombin time similar to a patient taking coumarin therapy.
