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.
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 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.

FAQs
About 5 percent of Americans who are 12 years old or older have hypothyroidism. Many people who have hypothyroidism are unaware.
Hypothyroidism is more common.
Currently, there is no evidence to support routine screening of your thyroid function. You may consider checking your thyroid function if you are having symptoms of a thyroid disorder or if you are at high risk for developing a thyroid disease.
If you have been diagnosed with a thyroid disorder, you may have your thyroid function checked more frequently. Consult with your healthcare provider to determine a longer-term care plan.
Even if you don’t have symptoms, you may consider testing if you have the following risk factors:
- Family history of thyroid disease
- Women
- People over age 50
- Have an autoimmune disease such as type 1 diabetes
- History of thyroid surgery
- Radiation treatment for a past thyroid condition
- Recent pregnancy
- Taking medication high in iodine
Initial testing for the evaluation of thyroid function should include TSH with reflex to serum T4 when TSH is abnormal. If treatment is started, recommended testing includes TSH and free T4 to be measured 6 weeks after initiation of treatment or if the dose is changed. Once steady state is achieved, annual monitoring of TSH is recommended or as needed if a patient develops new or worsening symptoms.
If treatment is not started, but retesting or monitoring is warranted, it is recommended to test TSH and/or T4.
Testing TPO antibodies is recommended for subclinical hypothyroidism, painless (silent) thyroiditis, Hashimoto disease, or postpartum thyroiditis, to predict the likelihood of progression to permanent overt hypothyroidism. TPO antibody can also be measured in the presence of a goiter in patients with normal TSH. The Thyroid Disorder Monitoring, Initial Panel does test for TPO. The Thyroid Disorder Monitoring, Ongoing panel does not test for TPO.
If thyroid (TSH) is abnormal, T4 is also performed on the sample you have already provided.
During the Consult, the Participant may discuss the results, get educational information, and talk about next steps. If the Participant’s results show that he or she has hypothyroidism, the PWN Physician may be able to prescribe medication, if appropriate.
