A urine culture is a test that checks your pee (urine) for bacterial or fungal (yeast) infections. “Culture” is the medical term for growing microorganisms (germs) from body fluids in a lab. Your healthcare provider will collect a sample of your pee and send it to a lab to be cultured.
A urine culture test also identifies the bacteria or yeast causing the infection and lets your provider know which antibiotics will work to kill the germs. This helps your provider select the most effective treatment.
