Abnormal Hemostasis Control Plasma
The VisuCon-F Frozen Unassayed Abnormal Control Plasma is a Abnormal Hemostasis Control Plasma for use in the quality control of coagulation assays in the mid-level abnormal 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 Unassayed Abnormal Control plasma is a pool of normal citrated human plasma collected from a minimum of 20 donors, diluted to defined concentration, buffered with 0.02M HEPES buffer, dispensed and rapidly frozen. This Frozen Abnormal Hemostasis Control Plasma is intended for use in the monitoring of the performance of PT, APTT and fibrinogen assays in the mid-level abnormal range.
This product is cleared for in vitro Diagnostic use by Health Canada and CE marked. They are available for sale in Canada and select European countries, not available in the United States.

The results obtained with the VisuCon-F Frozen Unassayed Abnormal Control plasma will be subject to the limitations of the assay system including types of reagents, factor deficient substrates and instrumentation.
Thaw each 1 mL vial for 5 minutes and each 4 mL vial for 7 minutes in a 37°C (+/- 1°C) water bath. Invert gently before use.
Storage and Stability:
Vials are stable until the expiration date stated on the vial when stored at –60°C or lower. Once thawed, the plasma is stable for 8 hours on-board or at 2-8°C in original vial. Thawed material should be discarded after use and not be refrozen.
After thawing the VisuCon-F Frozen Unassayed Abnormal Control Plasma, use on coagulation instrument or assay system with corresponding reagents in accordance with established coagulation assay procedures. The results obtained for the unassayed abnormal control plasma will depend on various factors including types of reagents, factor deficient substrates and instrumentation therefore each laboratory should establish its own mean values and expected reference ranges for quality control purposes in every coagulation assay using their particular instrument-reagent system.
