This study aimed at evaluating in outpatients an algorithm for the laboratory diagnosis of Clostridioides (Clostridium) difficile infection (CDI), i.e., enzyme immunoassays (EIAs) detecting bacterial glutamate dehydrogenase (GDH) and toxin A/B, followed by polymerase chain reaction (PCR) analyses of samples with discordant EIA results. In total, 9802 examinations of stool samples by GDH and toxin EIAs performed in 7263 outpatients and 488 inpatients were analyzed retrospectively. Samples with discordant EIA results had been tested by a commercially available PCR assay detecting genes of the C. difficile -specific triose phosphate isomerase (tpi) and toxin B (tcdB). Concordant EIA results (686 C. difficile -positive, 8121 negative) were observed for 8807 (89.8%; 95% CI, 89.2-90.4%) samples. Of 958 samples with discordant EIA results, 895 were analyzed using PCR and 580 of 854 GDH-positive/borderline, toxin-negative samples (67.9%; 95% CI, 64.7-71.0%) were positive for tpi and tcdB , while 274 samples (32.1%; 95% CI, 29.0-35.3%) were tcdB -negative. In contrast, 35 of 41 GDH-negative, toxin-positive/borderline samples (85.4%; 95% CI, 71.2-93.5%) were tcdB -negative. Still, 6 samples (14.6%; 95% CI, 6.5-28.8%) yielded positive PCR results for both genes. In conclusion, around 90% of the samples were analyzed appropriately by only applying EIAs. Approximately one third of the PCR-analyzed samples were tcdB -negative; thus, patients most likely did not require CDI treatment.
