Informativity of various methods of diagnostics of hypertherosis and accompanying pathology in cats

Thyrotoxicosis is most often recorded in cats over 12 years old. Simultaneously with hyperthyroidism, cats often have chronic renal failure, lower urinary tract infection, hypertrophic cardiomyopathy, and diabetes mellitus. Clinical examination of the thyroid gland by inspection and palpation allows to detect enlarged thyroid glands. Despite the fact that ultrasonography can detect changes in the tissues of the thyroid gland, determining the concentration of total thyroxine in the serum is the most accurate method for confirming the diagnosis. To determine the pathology associated with thyrotoxicosis in cats, general and biochemical blood and urine tests are needed, as well as arterial tonometry, echocardiography and ultrasonography.
