What is the primary goal of performing a urinalysis?

The primary goal of performing a urinalysis is to assess renal function and detect urinary tract diseases. This test provides valuable insights into the health of the kidneys and the urinary system by analyzing the physical, chemical, and microscopic properties of urine.

Urinalysis can help identify the presence of abnormal substances such as proteins, glucose, blood, or infection indicators, which can signify various renal issues or urinary tract diseases. For example, the presence of glucose can suggest diabetes, while blood may indicate infection or kidney stones. By evaluating these aspects, veterinarians can effectively diagnose and monitor conditions affecting the kidneys and urinary tract, which is essential for maintaining overall health in animals.

Other options, such as assessing liver function or diagnosing blood disorders, relate to different tests and would not provide the specific information that a urinalysis is designed to reveal. Likewise, cardiovascular health is evaluated through different diagnostic methods, making option B the most suitable choice in this context.
