Urinalysis can detect many diseases, for example, the most common ones can be evaluated for urinary tract infections, urinary tract stones, and urinary tract tuberculosis. It can also determine if there is celiac disease, crystalloid urine, or pus urine. If there is an increase in white blood cells in the urine, it suggests a urinary tract infection; if it suggests a large number of red blood cells, it should be noted that there may be urinary stones, but it is important to exclude whether there is a tumor in the urinary tract; if it is celiac disease, it should be considered that there is a disease in the lymphatic vessels. Urine tests can also reveal whether blood sugar is well controlled, such as urine sugar and urine ketone bodies, indicating that blood sugar and urine sugar are not well controlled, and diabetes should be adjusted; if urine bilirubin and urinary bilirubinogen are positive, indicating diseases of the liver and biliary system; if there is proteinuria, indicating pyelonephritis.
