Veterinary diagnostic tests are laboratory tests used to diagnose diseases in animals. These pet health tests use a variety of methods, such as blood tests, urine tests, swabs, tissue samples, and imaging to evaluate the animal's health. Veterinary diagnostic tests are essential in detecting and identifying diseases affecting both domestic and wild animals. They help in the identification and treatment of diseases, monitoring the progression of a disease, and assessing the effectiveness of therapy. Common veterinary diagnostic tests include Complete Blood Count (CBC), serum biochemistry, fecal tests, imaging tests, and tests for diseases such as heartworm, feline leukemia virus, and rabies. Veterinary diagnostic tests are critical in animal health care and public health.
