This panel evaluates Thyroid health with a focus on tests that can help differentiate between thyroid conditions.

What is this panel?

This comprehensive thyroid includes several tests designed to diagnose thyroid conditions. Tests include:

Thyroid-stimulating Hormone (TSH) – This test measures TSH, which stimulates the release of T3 and T4 thyroid hormones. Abnormal levels of TSH can point toward a thyroid disease, including hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). This test can also help monitor the effectiveness of thyroid hormone replacement therapy for patients who have already been diagnosed with a thyroid condition.
Triiodothyronine (T3), Free – Evaluate thyroid function and assess abnormal binding protein disorders.
Thyroxine (T4), Free, Direct - Free T4 may be indicated when binding globulin (TBG) problems are perceived, or when conventional test results seem inconsistent with clinical observations. It is normal in subjects with high thyroxine-binding globulin hormone binding who are euthyroid (ie, free thyroxine should be normal in nonthyroidal diseases).
Reverse T3 - Reverse triiodothyronine (rT3) is an isomer of triiodothyronine (T3) with no demonstrated biological activity.
Thyroid Peroxidase (TPO) Antibodies - Differential diagnosis of hypothyroidism and thyroiditis.
Thyroglobulin Antibody - This test is used to detect and confirm autoimmune thyroiditis and Hashimoto thyroiditis.
