PT Quick is the most common method to measure Prothrombin Time (PT), and is normally the assay of choice to monitor oral anticoagulat therapy. Moreover, PT Quick is used as a fundamental screening test for acquired or inherited bleeding disorders. MediRox PT Quick reagent is characterized by high sensitivity and easy to reconstitute.
Low ISI ~1
Calibrated against WHO international reference preparation
Reconstituted in purified water or diluent
Applicable on optical and mechanical instruments
MediRox PT Quick, MRX943 is a highly sensitive diagnostic reagent intended for use in performing PT tests. MediRox PT reagent provides a source of rabbit tissue thromboplastin and calcium that specifically activate factor VII in the extrinsic coagulation pathway. MediRox PT reagent is easy to reconstitute, calcium is already added to the reagent before lyophilisation. Calibration was performed against the most recent WHO thromboplastin standard, RBT/05, which is traceable to the first reference preparation of thromboplastins. The calibration assure low lot-to-lot variation and consequently results in reliable PT determination.
The prothrombin time is the method of choice for monitoring oral anticoagulat therapy and is a fundamental screening test for acquired or inherited bleeding disorders. During oral anti-coagulat therapy, the activity of vitamin K-dependant clotting factors (II, VII, IX, X, Protein C and Protein S) is reduced and PT time is increased thereby enable the quantitative determination of prothrombin activity.
