A urine analysis (UA) is a diagnostic test that examines the content and characteristics of urine. It is used to detect and manage a wide range of disorders, such as urinary tract infections (UTIs), kidney disease, and diabetes. The test involves a physical examination of the urine's color and clarity, a chemical analysis to check for substances like glucose and protein, and a microscopic examination to identify cells, crystals, and microorganisms. It is a non-invasive, quick, and widely used method to provide valuable insights into a person's health.
