Determining the Minimum Inhibitory Concentration of. 2/01/2014 · In order to determine an appropriate concentration range for the MBC-B assay, a good rule of thumb is to use 25 x MIC (minimal inhibitory concentration 11) as the middle concentration of the range and adjust accordingly. For the MBC-P assay, use 1/10 of the values identified for the MBC-B assay. The goal is to define a range of concentrations that will allow for a clear difference between …, The resulting minimum inhibitory concentration (MIC) is the smallest concentration in the series that inhibited growth of the bacteria. The MIC value is interval censored and the actual MIC is between the reported value and the next lowest concentration in the series (e.g., a MIC of 8 g/mL implies the actual MIC is between 4 and 8 ml/L). In some cases, the MIC data are collected in a complex.
