Urine analysis is a common diagnostic tool used to detect and monitor a variety of health conditions. It involves testing a urine sample for various substances, such as proteins, glucose, ketones, and cells, to assess kidney function, screen for diseases like diabetes, and monitor overall health. Urine analysis can also be used to detect drug use, pregnancy, and urinary tract infections. This non-invasive and simple test provides important information about an individual's health status and can help guide medical treatment and management.
