nine of these had their swabs taken eight or more days after onset of illness.Excluding samples taken after eight days, the sensitivity of PCR compared with any positive diagnosis (PCR, serology, and culture) was 94.2%.Conversely, 12 patients had positive results with PCR, but had negative results with serology.Thus, serology sensitivity compared with any positive result was 88.7%.An additional 10% of samples were positive by PCR in lysis buffer alone.Five of 13 samples that were negative for influenza and that were submitted in the first two weeks of the study were later confirmed by PCR to be rhinovirus infections.We acknowledge the hard work performed by the staff of the participating general practices.
