By Mayo Clinic staffUrinalysis is a test that evaluates a sample of your urine. Urinalysis is used to detect and assess a wide range of disorders, including urinary tract infection, kidney disorders and diabetes.
Urinalysis involves examining the appearance, concentration and content of urine. Abnormal urinalysis results may point to a disease or illness. For example, a urinary tract infection can make urine look cloudy instead of clear. Increased levels of protein in urine can be a sign of kidney disease.
Abnormal results of a urinalysis often require additional testing and further evaluation to uncover the source of the problem.
