《"Comparison of Xpert MTB/RIF, Real Amp, and CPA Tests in Detecting Mycobacterium tuberculosis"》
Note.16S:16S-23S rDNA internal transcribed spacer sequence analysis;CI:Confidence interval.PPV:Positive predictive value.NPV:Negative predictive value.
Of the 3,220 enrolled cases,303(9.4%)showed smear-positive results,2 had contaminated culture results,and 512(15.9%)had culture-positive results(Table 1).The rates of positive results for Xpert MTB/RIF,RealAmp,and CPA tests were 17.1%(551/3,220),18.8%(605/3,220),and 15.7%(504/3,220),respectively(Table 1).The performance of the solid culture,which was used as the gold standard for this research,may have affected the evaluation of the molecular assay.The culture contamination rate was found to be very low,potentially due to harsh specimen decontamination procedures.This may have decreased the sensitivity of the solid culture that can detect only live bacteria.
