VENLO, The Netherlands--(BUSINESS WIRE)--QIAGEN (NASDAQ: QGEN; Frankfurt Prime Standard: QIA) today announced that two of its tests can be used to screen for the swine flu virus which increasingly affects humans in countries around the globe. Data analysis of the viral gene sequences showed that both products already marketed, the artus Influenza LC RT PCR Kit and the Resplex II 2.0 Kit*, can be used to detect whether or not Influenza A virus sequences are present in a sample, including the H1N1 subtype. If the sample proves positive, treatment with widely available medication such as Tamiflu or Relenza can be prescribed, according to the recommendations given by the corresponding drug manufacturers.
