  • a F, female; M, male; Asym, asymptomatic; Sym, symptomatic.

  • b Specimens were interpreted as COBAS AMPLICOR false negative because they had yielded positive results in the AMPLICOR that were confirmed by a 16S rRNA test.

  • c Specimens were interpreted as COBAS AMPLICOR true negatives. They were subjected to 16S rRNA testing because they had yielded positive results in the AMPLICOR test format. The AMPLICOR results were interpreted as false positives.
