Determination of the LOD of the H275Y and N1 assays: nucleic acid extracted from an influenza A H1N1 oseltamivir-sensitive isolate was used to determine the LOD of the H275Y and N1 assays. The starting concentration of virus was 1500 TCID50/mL. Amplification curves for (A) H275Y and (B) N1 are shown.
