Thyroid Disorder Monitoring — Initial

This initial thyroid monitoring panel measures the levels of TSH, T4, and TPO antibodies in your blood. These markers help determine whether your treatment plan is working properly to manage your thyroid disease and can help your provider understand whether your thyroid function is impacted by autoimmune activity. Including TPO antibodies alongside TSH and Free T4 helps provide a more complete picture of thyroid health by distinguishing functional hormone changes from autoimmune activity affecting the thyroid.

This test is intended as a follow-up for those undergoing a treatment option after abnormal Thyroid Function (TSH) Test results.

If you have not been diagnosed with a thyroid disorder but you think you may have a thyroid disorder, consider the Thyroid TSH Function Test first. If you are looking for a more comprehensive hormone workup including everything in this panel plus T3, consider our Women's Hormone Test Panel — Expanded.

No doctor’s visit needed.

Please note: Noticeable changes in your metabolism (weight, temperature, and energy) may be a sign or symptom that there is too much or too little TSH in your blood. If TSH levels are too high or too low, this may indicate your thyroid is overactive (hyperthyroidism) or underactive (hypothyroidism). With this test panel, TSH, T4, and TPO blood levels are measured to help accurately determine whether your initial or adjusted treatment dosage is providing the correct level of support for your recently diagnosed thyroid disorder.

This test measures thyroid-stimulating hormone (TSH), free T4, and thyroid peroxidase antibodies (TPO), three key markers used to evaluate and monitor thyroid function.



About the thyroid

The thyroid is a butterfly-shaped gland in the front of the neck that helps regulate how your body uses energy. It plays a role in many essential processes, including metabolism, heart rate, body temperature, and nervous system function. Thyroid activity is regulated by the pituitary gland, which produces thyroid-stimulating hormone (TSH). TSH signals the thyroid to produce thyroid hormones—primarily T4, which the body converts as needed to T3. When this system is out of balance, it can lead to thyroid disorders that affect many parts of the body. While untreated thyroid disease can increase the risk of complications, most thyroid conditions can be effectively managed with medication and regular monitoring.
