The Comprehensive Thyroid Panel is a medical laboratory test that provides a comprehensive assessment of thyroid function by measuring various thyroid-related hormones and markers in the blood. It helps evaluate the overall health and performance of the thyroid gland, which plays a crucial role in regulating metabolism, growth, and development.

The panel typically includes several individual tests that together provide a comprehensive view of thyroid function. These tests commonly include:

• Thyroid-stimulating hormone (TSH): TSH is produced by the pituitary gland and regulates the release of thyroid hormones. Elevated or decreased TSH levels can indicate an underactive or overactive thyroid, respectively.
• Free thyroxine (FT4): FT4 is the active form of thyroid hormone circulating in the blood. It helps assess the thyroid’s ability to produce and release thyroid hormones.
• Free triiodothyronine (FT3): FT3 is another active form of thyroid hormone that plays a role in metabolism and energy production. Measuring FT3 levels provides additional information about thyroid function.
• Thyroid peroxidase antibodies (TPOAb): TPOAb is an antibody that targets an enzyme involved in thyroid hormone production. Elevated TPOAb levels may suggest autoimmune thyroid disorders like Hashimoto’s thyroiditis.
• Thyroglobulin antibodies (TGAb): TGAb is an antibody that targets thyroglobulin, a protein involved in thyroid hormone synthesis. Elevated TGAb levels can be seen in autoimmune thyroid conditions, including Graves’ disease.
