A urine culture is a laboratory test used to detect and identify bacteria or other microorganisms in the urine. It helps diagnose urinary tract infections (UTIs) and determines the most effective antibiotics for treatment. During the test, a urine sample is collected and placed in a special medium that encourages the growth of bacteria. After a few days, the culture is examined to see if any bacteria have grown. If bacteria are present, further tests may be conducted to identify the specific type and its sensitivity to various antibiotics. This information guides healthcare providers in choosing the right treatment for the patient.
