CD positive samples by culture and GDH positive samples by COMPLETE were 71 (16.4%) and 80 (18.5%) of 432 samples, respectively. Sensitivity and specificity of COMPLETE for detection of GDH were 100% and 97.5%, respectively. The toxin types of 71 samples were toxin A+B+ in 45, toxin A-B+ in 21, and toxin A-B- in five. In comparison, the toxin types of 44 samples whose toxin was detected by COMPLETE were toxin A+B+ in 31, and toxin A-B+ in 13. The sensitivity and specificity of COMPLETE for detection of toxin were 66.7% and 100%, respectively.
The combined use of COMPLETE and culture of suspicious CDI samples is beneficial for prompt detection of CD.
