Urinalysis Medical Test

Urinalysis is a physical and chemical examination of the urine. It is used to detect urinary tract infections and other disorders of the urinary tract. In patients with acute or chronic conditions, such as kidney disease, the urinalysis may be ordered at intervals as a rapid method to help monitor organ function, status, and response to treatment. Urinalysis can reveal diseases that have gone unnoticed because they do not produce striking signs or symptoms. Examples include diabetes mellitus, various forms of glomerulonephritis, and chronic urinary tract infections. The tests should be performed within 15 minutes after the urine is collected. Various tests can be conducted from the sample. Most of the screening urinalysis tests are measured by a reagent "dipstick" which contains little pads of chemicals that change color when they come in contact with the substances of interest. A part of a urinalysis can be performed by using urine dipsticks, in which the test results can be read as color changes. A urinalysis should accompany a screening chemical panel for complete interpretation of the serum chemistries.
