Clostridium difficile Ag Toxin A + B

Rapid immunochromatographic test for the qualitative detection of Clostridium difficile bacteria, Toxin A and Toxin B in feces. 

Clostridium Difficile: 

Relative sensitivity: 75/75=100% (95% CI: 96.08% ~ 100%)*

Relative specificity: 226/243=93.00% (95% CI:89.0% ~ 95.87%)*

Accuracy: (75+226)/(75+226+17)=94.7% (95% CI:91.58% ~ 95.87%)*

Toxin A 

Relative sensitivity: 32/33=96.97% (95% CI: 84.24% ~ 99.92%)*

Relative specificity: 47/49=95.92% (95% CI:86.02% ~ 99.50%)*

Accuracy: (32+49)/(32+1+2+47)=98.78% (95% CI:93.39% ~ 99.97%) *

Toxin B 

Relative sensitivity: 52/54=96.30% (95% CI: 87.25% ~ 99.54%)*

Relative specificity: 40/44=90.91% (95% CI:78.33% ~ 97.46%)*

Accuracy: (52+40)/(52+2+4+40) =93.88% (95% CI:87.15% ~ 97.72%)*
