What is the most critical step in any susceptibility test?
A) Plate streaking
B) Organism isolation
C) Gram stain identification
D) Inoculum preparation

Question

Quizplus · Accepted Answer

Inoculum preparation is the most critical step in any susceptibility test because it affects the accuracy of the results. The inoculum size, composition, and density need to be standardized to ensure that the test accurately reflects the bacteria's susceptibility to antimicrobial agents. If the inoculum is too sparse, the test may result in a false negative. Conversely, if the inoculum is too dense, the test may result in a false positive. Therefore, inoculum preparation is crucial in ensuring reliable and accurate susceptibility test results.
