Thyroid Panel - High (Hyperthyroid) FAQ
What does this panel test for?
Why is this panel important?
T4 is an important hormone secreted by the thyroid. A high T4 level indicates hyperthyroidism, even if the TSH is normal. In cases of mild hyperthyroidism, the TSH and T4 may be normal. In that case, the T3 level is helpful in identifying hyperthyroidism and determining the severity of hyperthyroidism.

Hyperthyroidism Test Panel - More Information
This hyperthyroidism panel, also known as a high thyroid test panel or an overactive thyroid blood panel, checks lab test markers that looks for a hyperactive thyroid gland.
Referred to as thyrotoxicosis in severe states, the main problem that defines hyperthyroidism is that the thyroid gland produces too much thyroid hormone. Hyperthyroid cases are caused by Graves' disease (the majority of cases in the US), thyroid inflammation, thyroid nodules and tumors.
Thyroid hormones are involved with a number of processes that keep the body's metabolism going. As a result, high thyroid hormone production during hyperthyroidism leads to an acceleration of metabolism in the body. Symptoms of hyperthyroidism include weight loss, hair loss, anxiety and mood disorders.
Getting a hyperthyroidism test near you at a Quest Diagnostics lab is a relatively straightforward process. After you order online, you will need to visit the selected lab near you and get your blood drawn. No fasting is required for this hyperthyroidism blood test panel. Most people with hyperthyroidism will show relatively low TSH levels and high T3 and T4 total and/or free levels on their lab results. For people who want a simpler screening test that might identify an overactive thyroid, it is also worth considering getting a TSH test.
Hyperthyroidism is treatable using medications, radiation therapy and surgery. In many cases, treatment will involve destroying much of the thyroid resulting in the need for long-term thyroid hormone supplementation.
