Test Overview
Minimum Bactericidal Concentration (MBC) and Minimum Inhibitory Concentration (MIC)
Determining the in vitro susceptibility of aerobic bacteria involved in human infections. An MBC identical to or very close to a sufficiently low MIC indicates that significant killing of the organism has occurred. A "susceptible" category result and a low MIC value indicate in vitro susceptibility of the organism to the antimicrobial tested. Both the MIC and MBC should be within the range of usually achievable antibiotic blood levels for the organism to be considered "susceptible" (inhibited or killed) to the antimicrobial.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Specimen Requirements
When an MBC test is desired, the physician must request that the patient`s isolate be saved within 7 days of initial culture date, and arrange with the Microbiology lab to prepare the bacterial isolate for the MBC test. Indicate organism identification, antibiotic(s) to be tested, specimen source, and collection date/time.
Bacteria should be in pure culture, actively growing, placed in a proper mailing container (agar plates are not acceptable), and labeled as an etiologic agent. Keep at room temperature. If culture was done by MLabs, contact the MLabs Client Services Center within 7 days of initial culture date to request that the patient's isolate be saved for MBC testing. Indicate organism identification, antibiotic(s) to be tested, specimen source, and collection date/time.
