TABLE 1.

Results of replicate tests in eight laboratories using 5-μg posaconazole disks on MH-GMB^a

^aMH agar was supplemented by adding GMB before autoclaving.

^bBased on ten replicates of two disks on each of three lots of media in eight laboratories per strain. The quality control limits (with the percent included) for tests with each control strain were as follows: C. albicans ATCC 90028, 24 to 34 mm (96.5%); C. parapsilosis ATCC 22019, 25 to 36 mm (97.2%); C. tropicalis, 23 to 33 mm (97.3%); and C. krusei, 23 to 31 mm (96.0%). The percent included refers to the percentage of zones that fell within the proposed control limits, as calculated for the data from all eight laboratories. Brackets designate the all-laboratory median zone diameters for each data set.
