If the Minimal Inhibitory Concentration (MIC) or Zone Size Is

If the minimal inhibitory concentration (MIC) or zone size is interpreted as resistant using the latest Clinical and Laboratory Standards Institute (CLSI) tables:

A) the clinical interpretation of the result is that the patient's infecting organism should respond to therapy with that antimicrobial agent using the dosage normally recommended for that type of infection and that species.
B) the patient's infecting organism is unlikely to be inhibited by the usually achievable concentrations of the antimicrobial agent based on the dosages normally used with that drug.
C) the patient's infecting organism is likely to require the maximum amount of antimicrobial or more than can be achieved and for which the clinical response is likely to be less than with a susceptible strain.
D) none of the above.
