About the Test

The Thyroid Disorder Monitoring, Initial Test 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. This test is intended as a follow-up for those being provided a treatment option after taking our Thyroid Function Test.


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. If you have not been diagnosed with a thyroid disorder but you think you may have a thyroid disorder, we strongly recommend you consider the Thyroid Function Test first.
