Sentences with phrase «in faecal samples»

The study compared the main different ways of diagnosing C - Diff, including the two «gold - standard» methods: a cytotoxin assay, which looks for the presence of C - Diff toxin in faecal samples; and cytotoxigenic culture, which looks to see if there are bugs present in faecal samples that could possibly produce C - Diff toxin.

The findings mean that tests which detect the presence of toxin in faecal samples (the cytotoxin assay) are the most reliable indicators of true C - Diff.
