During a urine examination, the veterinarian looks for anomalies such as the presence of a higher amount of red or white blood cells, abnormal cells, crystals, glucose or proteins. Proteins in urine can indicate general conditions such as high blood pressure and/or deviations of the kidney filtering system. A change in urine pH can point to a bacterial infection. The specific gravity of urine shows how well the kidneys concentrate urine. Glucose (sugar) in urine can be suggestive of diabetes.
