Urinalysis for Horses: A Veterinarian’s Guide to Urine Testing
Urinalysis is a simple yet powerful diagnostic tool that can provide valuable insights into a horse’s overall health. By examining the appearance and composition of urine, veterinarians can assess kidney function, hydration status, and the presence of certain toxins. Although often overlooked compared to bloodwork or imaging, urinalysis plays an important role in equine medicine as part of a complete diagnostic workup. A standard urinalysis evaluates several components: physical properties such as color, clarity, and odor; chemical properties including pH, protein, glucose, and the presence of blood; and microscopic examination of cells, crystals, and other sediment. These findings, when combined with clinical signs and other diagnostic tests, can help veterinarians detect conditions such as urinary tract infections, bladder stones, kidney disease, and systemic illnesses like metabolic disorders. For horse owners, knowing when a urinalysis might be useful and what it can reveal is an important part of proactive health care. Whether your horse is showing obvious urinary symptoms or experiencing vague changes such as weight loss or poor performance, a urine test can provide answers that guide treatment and management. In this article, we’ll explore the basics of urinalysis in horses, how samples are collected, what results mean, and when this test is most beneficial.
