The MBC is defined as the lowest concentration of an antimicrobial agent needed to kill 99.9 percent of the initial organism inoculum. Presently, specific guidelines for interpretation are not available; therefore, a clinician knowledgeable in both bactericidal testing and infectious diseases should be available to interpret the results.
For serious infections with coagulase-negative staphylococci, testing for the presence of mecA will be performed in order to interpret the results for agents.
This test must be ordered for each antimicrobial agent tested.
The minimum turnaround time is 48 hours for nonfastidious, rapidly growing organisms and greater than or equal to 96 hours for fastidious, slow growing organisms.
An additional processing fee will be billed for all organisms submitted that are not in pure culture as indicated in the specimen requirements.
If species identification is not provided, identification will be performed at ARUP. Additional charges apply.
