Abstract:
:A total of 525 cerebrospinal fluid (CSF) samples submitted during the 2007 and 2008 enteroviral seasons were included in a study to determine the prevalence of and potential risk factors for invalid Cepheid GeneXpert enterovirus assay (GXEA) results, as well as possible solutions for the problem. The invalid GXEA results were reported for 43 (8.2%) specimens and correlated with increased visibility of red blood cells (P < 0.0001) but not with CSF xanthochromia and clotting. Invalid GXEA result rates were markedly diminished by 82.1% and 96.0% and test sensitivities were minimally decreased by 1.7% and 3.6% when these specimens were tested at a 1:5 dilution and after a freeze-thaw cycle, respectively.
