The diagnosis of feline hyperthyroidism is straight-forward in many cats. However, the diagnosis can be less clear in early hyperthyroidism or in cats with non-thyroidal disorders. Monitoring thyroid therapy can also be confusing in certain patients. This lecture will emphasize the use of specific thyroid tests (total T4, fT4 and eTSH) to best determine thyroid status and provide therapeutic monitoring in feline hyperthyroidism.
