Urine Cytology

Cytologic examination of the urine sediment in animals suspected of having urinary tract disease or lower urinary tract masses is one of the best means of distinguishing inflammation, infection, and neoplasia and can help determine if a positive dipstick result for hemoglobin/blood is due to hemorrhage or blood contamination. The quality of the specimen collection and handling plays an important role in the quality of results, the validity of interpretations, and selection of appropriate course of action. The method of sample collection aids localization of pathology. Air dry but do not heat fix, freeze, or expose films to formalin fumes, temperature extremes, or condensation.
