Frozen Abnormal Control Plasma

Control Plasmas

The VisuCon™-F Frozen Abnormal Control Plasma is intended for use in the quality control of coagulation assays in the borderline pathological range. Good laboratory practice requires that assays be calibrated over the relevant range and that controls be performed regularly to confirm assay calibration. The VisuCon-F Frozen Abnormal Control Plasma is a pool of normal citrated human plasma collected from a minimum of 20 donors, diluted to defined concentrations, buffered with 0.02M HEPES buffer, dispensed and rapidly frozen.  This Abnormal Control Plasma may be used to monitor the performance of coagulation assays for the following parameters: fibrinogen (Clauss Method), coagulation factors II, V, VII, VIII, IX, X, XI, XII, antithrombin, Protein C, and Protein S.

Each box of VisuCon-F Frozen Abnormal Control Plasma contains a lot-specific Certificate of Analysis with the assigned reference ranges for each parameter. The reported reference ranges were determined against, where available, the SSC/ISTH secondary coagulation standard that is traceable to current WHO International Standards.
