What is urine culture and sensitivity?

Urine culture is when a doctor orders a urine specimen to be evaluated in a lab to determine exactly what kind of bacteria are living in it and causing problems. "Culture" means to grow, and they literally grow the bacteria so that they can test different antibiotics on it. Some antibiotics may kill the bacteria, and some antibiotics have no effect on the bacteria. This is the "sensitivity" part. If a bacteria is sensitive to an antibiotic, it would be a good choice for treatment of the infection. If it is not sensitive, the it is resistant to the antibiotic and it won't produce a cure.
