What is an advantage of automated systems for antimicrobial susceptibility testing?

• A. Reduces time to definitive culture results
• B. Increases manual labor
• C. Not readily available
• D. Cannot test most common organisms

Answer: (A)

Automation speeds up antimicrobial susceptibility testing by handling inoculation, incubation, growth detection, and interpretation with validated algorithms, producing definitive results more quickly than manual methods. This streamlined workflow reduces hands-on time and provides faster, standardized readouts that support faster clinical decision-making. The other statements don’t fit because automation typically lowers manual labor, is widely available in many labs, and can test most of the common organisms encountered; limitations may exist for some rare organisms or antibiotics, but those do not negate the overall advantage of reduced time to results.
