Summary of reproducibility data
The reproducibility of MIC tests at 3 trial sites was measured against:
25 Gram-positive isolates
25 Streptococcus spp. 25
Haemophilus influenzae
25 Candida spp.
Testing was performed using Sensititre™ plates read on the Vizion™ system, AutoReader™ system, and
mirror. Reproducibility was calculated as occurrences of the difference in number of wells between the
test result and test mode. Percentages of results were calculated for the combined sites plus or minus
one dilution of the modal value (best and worst case scenarios assuming the off scale result is within one
well from the mode and assuming the off-scale result is greater than one well from the mode) for all sites.
The MIC values were off-scale for a large number of isolates, which has resulted in low performance
based on "worst-case" calculations, the overall reproducibility was considered acceptable, since very high
