Table 2 Performance of the DNA microarray assay for detection of resistance to INH and RMP compared with phenotypic DST

From: Rapid and accurate detection of RMP- and INH- resistant Mycobacterium tuberculosisin spinal tuberculosis specimens by CapitalBio™ DNA microarray: A prospective validation study

Phenotypic DST DNA microarray assay
Sensitivity Specificity
Correct-no./total no. (%) 95% CI Correct-no./total no. (%) 95% CI
RMP resistance 16/18 (88.89) 74.37-100.00 68/75 (90.67) 84.08-97.25
INH resistance 11/15 (73.33) 50.95-95.71 71/78 (91.03) 84.68-97.37
