Dx Focus: Clinical and Regulatory PCR and Nucleic Acid Testing News: Jan 13, 2011

Nanosphere said this week that it has received 510(k) clearance from the US Food and Drug Administration for its Verigene Respiratory Virus Plus nucleic acid test on the Verigene system.

The RV+ test detects influenza A, influenza B, respiratory syncytial virus A, and RSV B in a single test; and further subtypes influenza A as H1, H3, or 2009 H1N1.

The test automates the steps of viral RNA extraction, multiplexed PCR amplification, and target detection on the Verigene system, and requires only a single pipetting step, the company said. The company also noted that RV+ was operationally similar to Nanosphere's existing respiratory assay that was cleared on the same Verigene system and received a CLIA categorization of moderate complexity.
