The new TAS PT-NC Controls are intended to be used with the TAS Analyzer and PT-NC test cards to provide a method for quality control of the system. The controls produce clotting times which must be within accepted, standard ranges, to indicate that the analyzer and test cards are functioning properly and thereby help assure the accuracy of PT-NC test card results. These controls were designed to allow CVDI's point-of-care tests to maintain accepted laboratory standards and requirements. These controls also can be used to determine system (TAS Analyzer and PT-NC test cards) precision. The controls are substantially equivalent in intended use to other control materials used in coagulation tests.
