What does this panel test for?
This panel checks your levels of Free & Total T3, Free & Total T4, Thyroglobulin Antibodies, Thyroid Peroxidase Antibodies (TPO), and Thyroid-stimulating Hormone (TSH).
Why is this panel important?
The Hashimoto's panel helps screen for Hashimoto's disease. Hashimoto's disease is caused by gradual destruction of thyroid cells from an overactive immune system. While it often causes fatigue and sluggishness, it can also cause periods of anxiety and hyperactivity.
Thyroid Peroxidase Antibodies and Thyroglobulin Antibodies are immune system components against thyroid proteins that are elevated in Hashimoto's Disease. If the immune system is overstimulated, these antibodies can lead to Hashimoto's by causing damage to the thyroid. In Hashimoto's disease, the TSH (Thyroid Stimulating Hormone) will often be elevated because it is trying to produce more thyroid hormone. The T3 and T4 tests will measure the actual levels of these thyroid hormones. In the initial stages of Hashimoto's, these levels may be elevated as the thyroid keeps up with destruction of the hormones by antibodies. Over time, these levels will be low.
