Urine Culture

Urine Culture

Test Overview

A urine culture is a test to find germs (such as bacteria) in the urine that can cause an infection. Bacteria can enter through the urethra and cause a urinary tract infection (UTI).

A sample of urine is added to a substance that promotes the growth of germs. If no germs grow, the culture is negative. If germs grow, the culture is positive. The type of germ may be identified using a microscope or chemical tests.

UTIs are more common in women and girls than in men. This may be partly because the female urethra, Opens dialog is shorter and closer to the anus. This allows bacteria from the intestines to come into contact more easily with the urethra. Men also have an antibacterial substance in their prostate gland, Opens dialog that lowers their risk.
