Urine and your health

A urine test, also known as a urinalysis, can reveal a great deal about a person’s health. The kidneys produce urine to remove excess fluid and waste products from the body. But urine also contains various chemicals, minerals, toxins, bacteria, and red and white blood cells. Analyzing a urine sample with visual, chemical, and microscopic exams can reveal the presence and amounts of these substances, which can provide clues to specific conditions.
