From: Detection of carbapenemase-producing Enterobacteriaceae in rectal surveillance cultures in non-hospitalized patients

  Sensitivity Specificity PPV NPV
Chrom-KPC 100% 100% 100% 100%
MHT 66.7% 100% 100% 20%
  1. Sensitivity (MHT)8/12 = 66.7%, specificity = 1/1 = 100%, PPV = 8/8 = 100%, NPV = 1/5 = 20%
