VIRAQ CHECK CONTROLS FOR NON-ENVELOPED VIRUS NAT ASSAYS
ViraQ Check Controls for NAT methods detecting non-enveloped viruses are prepared from native plasma standards. The Controls are diluted in a plasma matrix containing neutralising antibodies. The infectivity thresholds are expected to be above the concentrations in the run controls. Hence, inactivation of the viral standards is not necessary. The controls are at close distance to the 95% LOD of the NAT assays except for parvo B19V that contains 10,000 IU/mL of the secondary VQC-Sanquin standard. This reference plasma has been extensively calibrated against the 1st WHO 99/800 standard. The dual ViraQ B19V/HAV control and HEV control are suitable for both the Grifols Procleix and the Roche cobas assays. It must be emphasized that the secondary VQC-Sanquin B19V standard has not been calibrated against the recently introduced 3rd WHO 12/208 standard.
