ProFlu-ST is cleared for use until April 26, 2010.

Gen-Probe has been granted an EUA (emergency use authorization) for the Prodesse ProFlu-ST™ to be used in CLIA high-complexity laboratories for detection of the 2009 H1N1 influenza virus. The test is aided by an algorithm that relies on seasonal influenza A/H1 and A/H3 virus results from a single sample in individuals who are diagnosed with influenza A by currently available devices.

Under the EUA, the agency has authorized the use of ProFlu-ST only during the H1N1 flu emergency, which is currently set to expire on April 26, 2010. The test becomes the first commercially available RT-PCR diagnostic that can detect and identify the 2009 H1N1 influenza virus, according to Gen-Probe. Test results are reportedly obtained in three hours using the assay; culture-based methods can take up to weeks to produce a result, the firm adds.

“This test complements nicely our FDA-cleared ProFlu+ Assay, which from a single sample, detects and discriminates influenza A virus, influenza B virus, and RSV (respiratory syncytial virus),” notes Andy Shrago, head of marketing for Prodesse products.

Both the ProFlu-ST and ProFlu+ tests were obtained through the acquisition of Prodesse, completed on October 21. Prodesse had three FDA 510(k)-cleared products and two additional CE-marked products in Europe.

Prodesse’s ProFlu+ test was sanctioned by the FDA in January 2008 for the detection and discrimination of influenza A virus, influenza B virus, and RSV. Prodesse also sold assays for the clinical diagnosis of Clostridium difficile and human metapneumovirus in the U.S.
