ABSTRACT: Antimicrobial susceptibility testing by the so called quantitative disc diffusion method offers a reproducible test which can be performed in most laboratories. Standardisation of the disc method is essential. In addition, accuracy of the results is improved with the introduction of several species-related exceptions according to recommendations by NCCLS. Further species-related control of the performance in the individual laboratory is recommended using histogram analysis. Major type of interpretive errors in disc diffusion tests are described. For more specific calibration of the disc test, the so called single-strain regression analysis might be employed in collaboration with a reference authority or disc manufacturer.
