Urine is normally sterile, which means that it contains no bacteria. A small number of bacteria may be found in the urine of many healthy people. This is usually considered to be harmless. However, a certain level of bacteria can mean that the bladder, urethra, or kidneys are infected.

A urinalysis, also called a urine test, can detect the presence of nitrites in the urine. Normal urine contains chemicals called nitrates.
