The Urine Routine Examination (or Urinalysis) is the single most important "check-engine light" for your overall health. It's a simple, non-invasive, yet incredibly powerful test that provides a broad snapshot of your body's function. This comprehensive, three-part exam includes: 1) A visual check for color and clarity, 2) A chemical (dipstick) test for glucose, protein, ketones, blood, and signs of infection, and 3) A microscopic exam to look for cells, bacteria, or crystals. It is the foundational, first-line test for diagnosing UTIs, kidney disease, and diabetes. This is a non-negotiable, essential part of any annual health check-up for you and your family.
