Urinalysis is non-invasive, easy to obtain, and can provide very valuable information on kidney and urinary tract diseases, hepatobiliary and pancreatic diseases, cardiovascular diseases, and systemic diseases such as endocrine, metabolic, hemorrhagic, and neoplastic diseases. Urine routine is a collective term for a number of fixed combinations of indicators in the urine. Routine urine examination is one of the most commonly used tests in medical diagnosis, and its purpose is to understand the general condition and changes of the body’s urinary system, as well as whether diseases of other organs have any effect on kidney function, and whether drug treatment has any effect on the kidneys. Routine urine tests generally include urine protein, urine sugar, urine ketone bodies, urine specific gravity, acidity, urine bilirubin, urine bilirubinogen, nitrite, red blood cells (occult blood) and white blood cells. Each indicator in the routine urine test represents a different meaning, and based on the indication of the routine urine test results, the chief examining physician can give relevant conclusions.
