Rapid diagnostic tests can help achieve antimicrobial stewardship goals by offering which benefits?

• A. Decreased time to microorganism identification
• B. Easy identification of resistance mechanisms
• C. Both of the above
• D. None

Answer: (C)

Rapid diagnostic tests support antimicrobial stewardship by providing two key advantages at once: quicker identification of the infecting organism and clearer information about its resistance features. When the pathogen is identified sooner, clinicians can shift from empiric broad-spectrum therapy to targeted therapy earlier, which reduces unnecessary exposure to broad-spectrum drugs and helps preserve their effectiveness. At the same time, many rapid tests reveal resistance mechanisms—whether by detecting specific resistance genes or by signaling resistance phenotypes—making it easier to choose an antibiotic that will actually work. Together, these benefits enable earlier optimization of therapy, promote de-escalation when appropriate, and support efforts to contain resistant organisms. That combination explains why this item points to both benefits as the rationale for rapid diagnostics in stewardship.
