GenoType® MTBDR<I>plus</I> assay detection of drug-resistant tuberculosis in routine practice in Korea

Abstract

The specificity of the MTBDR assay in detecting MDR-TB was very high, although the sensitivity in detecting INH resistance and MDR-TB was not optimal (<95%). Although the turnaround time in detecting drug resistance was dramatically reduced with MTBDR compared to conventional DST, more effort is needed to shorten the turnaround time.
