WebObjectives: C. difficile Infection (CDI) can be challenging to diagnose due to high colonization rates. Unlike PCR-only testing, two-step algorithm testing (that includes toxin and PCR) may help differentiate colonization from active infection, but it is unknown if this type of testing impacts treatment decisions. WebThe 47 colonized and 41 symptomatic children with positive NAAT had stool tested for C. difficile toxin via EIA and CCNA as previously described. EIA positivity (44% vs 26%, P = 0.07) or CCNA positivity (49% vs 45%, P = 0.70) did not differ between symptomatic and colonized children although a trend toward more positive testing in symptomatic children was …
