A urine culture gives microorganisms several days to grow in a suitable growth medium. The sample is then examined under a microscope to detect the presence and extent of growth. 

The test is positive if the culture shows signs of bacteria or other microorganisms. In the case of less or no growth, the test is negative.

Why do I need Urine Culture?
