Diagnosis Sidebar

 1. Laboratory diagnosis (most common).  A sample of blood is tested for the level of circulating thyroid hormone. The levels of thyroid hormone in Hyperthyroid cats can be mild, (just above normal) or levels 2 -3 times normal. Concurrent kidney disease is common and should be evaluated before and after therapy. Other testing may include feline leukemia and feline immune deficiency virus.

2. Thyroid tissue function can be measured by the Radiopharmacuetical TC99.  This compound acts like iodine and is absorbed by the hyper functioning thyroid tissue. The gland is then examined using a sensitive gamma camera radiation detection devise. The advantage is that the abnormal tissue can be identified as to location and hyperactivity. Abnormal tissue can be located anywhere from the base of the tongue to the base of the heart. 70% of the cases involve hyperfunctioning tissue in multiple sites. Up to 5% of the cases involve thyroid carcinoma (cancer) which usually involves metatastic lesions in the lungs.
