Urinalysis is a laboratory test that examines urine to assess a person's health. It helps detect various conditions, such as infections, kidney disease, and diabetes. The test typically involves analyzing the physical, chemical, and microscopic properties of urine. During a urinalysis, a sample of urine is collected and tested for specific substances, including proteins, glucose, and blood. The results can provide valuable information about a person's overall health and guide further medical evaluation or treatment if necessary.
