Abstract

The diagnostic gains of repeat testing for Clostridium difficile by enzyme immunoassay and PCR (i.e., initial negative result followed by positive result) within a 7-day period were 1.9 and 1.7%, respectively. There is little value of repeat testing for C. difficile by enzyme immunoassay or PCR.
