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

The results obtained with the VisuCon-F Frozen Unassayed Normal 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 Normal Control Plasma, use on coagulation instrument or assay system with corresponding reagents in accordance with established coagulation assay procedures. If appropriate control values are not obtained, assess the components of the assay system including reagents, substrate plasmas, calibrator plasma or instrumentation to try and identify potential sources of error.
