A urinalysis is a test of your urine. A urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes. A urinalysis involves checking the appearance, concentration and content of urine. Abnormal urinalysis results may point to a disease or illness.
In patients who have kidney disease or diabetes, urine tests are used to monitor the condition. Urinalysis also may be performed to detect a urinary tract infection (UTI), protein in the urine (proteinuria), or blood in the urine (hematuria), and to diagnose pregnancy. Toxicology screening can be used as part of urinalysis to detect illegal drug use. This is not part of routine urine testing.
