Quality control of antimicrobial susceptibility tests involves
A) performing antimicrobial susceptibility tests on organisms using the CLSI charts to interpret the results.
B) using organisms grown from patient cultures to test the reactivity of the antimicrobial drugs.
C) testing standard reference strains that have defined antimicrobial susceptibility (or resistance) to the drugs tested.
D) None of the above

Testing standard reference strains with defined antimicrobial susceptibility to the drugs being tested is the correct way to ensure quality control. The use of patient cultures, while important for clinical purposes, can be affected by variables such as patient factors and specimen collection, which can impact the accuracy of the test results. Using CLSI charts to interpret results is also important, but only after the quality control step has been established.
