| Urinalysis is an important laboratory test that can be readily performed in veterinary practice, and is considered part of a minimum database. It is useful in documenting various types of urinary tract diseases and may provide information about other systemic diseases, such as liver failure and hemolysis. Urine may be collected by cystocentesis, urethral catheterization, or voiding and should be evaluated within 30 min. If this is not possible, then it may be refrigerated for up to
24 hr; however, this may alter results of some tests, such as pH, protein, and sediment examination (crystals, casts, and cells). |
