The lab test that involves growing bacteria and testing antibiotics is:

• A. Urine dipstick analysis.
• B. Urine culture and sensitivity.
• C. Renal function panel.
• D. Complete blood count.

Answer: (B)

Growing the organism from the patient’s sample and testing which antibiotics can effectively inhibit its growth is what this test does. A urine culture and sensitivity identifies the bacteria causing the infection and then assesses its susceptibility to different antibiotics, guiding the choice of therapy and helping prevent resistance. Urine dipstick analysis looks for chemical markers like nitrites or leukocyte esterase, not live bacteria or antibiotic options. A renal function panel evaluates kidney function and electrolyte status, not infection specifics. A complete blood count shows blood cell levels and signs of systemic infection but does not determine which antibiotic will work.
