Quizplus · Accepted Answer

The factors affecting results include antibiotic potency, inoculum, concentration, and pH.The bactericidal level of antibiotic and anion content does not affect susceptibility results.Other factors affecting results include agar depth, evaporation, cation content, thymidine content, instrument failure, temperature, moisture, and difficulty in determining endpoints.
