Table 2.

The number of individual patients in whom no treatment against C. difficile infection was initiated when the test results were known

Results*	No. of individual patients tested**	No. of individual patients in whom no treatment against C. difficile was initiated (%)
GDH negative, NAAT positive	10	7 (70.0)
GDH positive, NAAT negative, toxin A&B EIA negative	34	29 (85.3)
GDH positive, NAAT positive, toxin A&B EIA negative	31	7 (22.6)
GDH positive, NAAT positive, toxin A&B EIA positive	28	4 (14.3)

*No patients had a GDH-positive, NAAT-negative and EIA-positive result. The combination of a GDH-negative and toxin A&B EIA-positive result was not possible since the toxin A&B EIA was performed only if the GDH test was positive

**Some patients were tested multiple times
