About the test

Thyroid Disorder Monitoring, Ongoing Test Panel measures the levels of TSH and T4 in your blood. These markers help determine whether your current treatment plan is working properly for your thyroid disease. This test is intended as an additional follow-up to our Thyroid Disorder Monitoring, Initial Test Panel.

This testing option is intended for patients with a known thyroid function disorder and may be recommended by a PWN physician as a follow-up to our Thyroid Disorder Monitoring, Initial Test Panel once treatment has started.


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 and T4 blood levels are measured to help accurately determine whether your treatment dosage is providing the correct level of support.

This panel does NOT test for thyroid peroxidase (TPO) antibodies in your blood. See FAQs.
