The purpose of the qualification work. The aim of the study was to find informative parameters for diagnosing hyperthyroidism in cats. After diagnosis was made, treatment with the use of antithyroid drugs was prescribed (Carbimasol for the control group of cats and Tiamazol for the experimental group of animals). Task: The aim of the study was to diagnose hyperthyroidism in cats using next parameters: anamnestic data, clinical examination, ultrasound thyroid examination, hematological and biochemical studies determination of total serum thyroxine (T4). And estimate efficiency of treatment of cats with thyrotoxicosis. Object of study. The object of the study were 10 cats with clinical sign of thyrotoxicosis Subject of study. Hyperthyroidism in cats. Theoretical and practical significance of the obtained results. The main symptoms and indicators for diagnosis are: increasing the size and structure of the thyroid gland (the thyroid gland was increased in size bilaterally in 80 % of cats and unilateral in 20 % of animals, 241,1 mm3 to 493,7 mm3. And pathognomonic parameter for diagnosis hyperthyreosis in cats was increase in the level of total T4 in of blood: 90,20±1,15 and 97,90±1,36 nmol/l. Normal values of T 4 -10-60 nmol/l. Cats with subnormal T4 values are almost euthyroid sick or overtreated for hyperthyroidism. Older cats with consistent clinical signs and T4 concentration in gray zone 30-60 nmol/l may have early hyperthyroidism or a concurrent non-thyroidal illness. Hyperthyroidism may be confirmed in these cats by adding on free T4 or by performing a T3 suppression test. popup.nrat_date 2025-11-21 Close
