For antibiotic use, what was a major barrier for practitioners to conduct a culture and sensitivity test?

• A. Time to results
• B. Cost
• C. Lack of access to laboratories
• D. Uncertain clinical benefit

Answer: (B)

Economic considerations shape how often culture and sensitivity tests are used in antibiotic prescribing. While these tests can pinpoint the exact pathogen and its susceptibilities, the direct costs of performing the test—lab processing, reagents, and personnel—plus potential lack of reimbursement or out-of-pocket expense for patients, often deter routine use. Clinicians may opt for empiric therapy instead when the upfront cost is a barrier, especially in settings with limited resources or when the anticipated benefit is weighed against delays and additional expenses. Time to results, lack of access to laboratories, and doubts about the test’s impact can influence decisions as well, but the financial burden frequently stands out as the strongest practical obstacle to ordering culture and sensitivity tests.
