The VisuCon™-L Coag Screen N plasma is a normal control plasma intended for use in the quality control of coagulation assays, including Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT) and fibrinogen, in the normal range. The VisuCon-L Coag Screen N plasma may be used with mechanical and photo-optical coagulation instruments in conjunction with appropriate commercial reagents. Good laboratory practice requires that assays be calibrated over the relevant range and that controls be performed regularly to confirm assay calibration. The VisuCon-L Coag Screen N plasma is a pool of normal citrated human plasma collected from a minimum of 20 donors, buffered with 0.05M HEPES buffer, as well as stabilizing agents, dispensed and lyophilized.

The results obtained with the VisuCon-L Coag Screen N plasma will be subject to the limitations of the assay system including types of reagents and instrumentation.
