The thyroid gland is a small, butterfly-shaped endocrine gland located at the front of the neck. It plays a major role in regulating metabolism, hormone levels, and vital body functions such as heart rate, energy, skin health, muscle and bone development, and brain activity. When the thyroid isn’t functioning properly, it can disrupt everything from mood and weight to your menstrual cycle, appetite, and immune system.

Problems with the thyroid can also be associated with obesity and weight loss failure. As a result, thyroid tests go hand-in-hand with fitness and weight loss labs. Find out more about the thyroid blood tests and other related screening tests as you read further.

The Role Of Thyroid Testing

A thyroid function panel provides valuable insight into how well your thyroid is performing and whether hormone levels are within a healthy range. It helps detect hormone imbalances, autoimmune conditions like Hashimoto’s thyroiditis and Graves’ disease, and nodules that may affect the function of the endocrine system.

Thyroid testing is often part of a broader health evaluation, as it informs treatment decisions for those taking medication such as levothyroxine or propylthiouracil. It also helps monitor therapy effectiveness and adjust dosage as needed. Testing is especially important for patients with risk factors like iodine deficiency, autoimmune disease, menopause, kidney disease, or recent pregnancy. If you’re using biotin supplements or other drugs that affect test results, your physician may also recommend scheduling your test accordingly.

Our thyroid testing kits offer a convenient and reliable way to screen for abnormalities. Using a simple venipuncture blood sample collected at a partner facility, your test evaluates key markers of thyroid health without the need for a doctor’s office visit.

Types Of Thyroid Function Tests

Thyroid testing typically includes a panel of hormone, antibody, and protein markers that help paint a complete picture of thyroid function. Your health care provider will recommend the appropriate test based on your symptoms, history, and risk level.
Some commonly ordered thyroid blood tests include:
  1. Thyroid-stimulating hormone (TSH) Blood Test
  2. Thyroid Peroxidase TPO Antibodies Blood Test
  3. Thyroxine, T4, Free, Direct, Serum Blood Test
  4. Triiodothyronine Free (T3, Free) Blood Test
  5. Thyroglobulin Antibody Blood Test

Who Should Get Thyroid Blood Tests?

Individuals who experience symptoms of thyroid disease like neck enlargement, fatigue, trouble sleeping, muscle weakness, irregular menstruation, nervousness, and the like should take a test for thyroid function.

Additionally, those who are at risk for thyroid disorders should also get a thyroid test. This includes women above 60, those with a family history of thyroid disease, recently pregnant women, and individuals diagnosed with autoimmune disease.

When To Do Thyroid Function Lab Tests?

Take the thyroid test at the onset of the symptoms of thyroid disease or other related problems. With early diagnosis, your chances of getting less complex treatment increase, paving the way to a swift recovery. Moreover, since women are more at risk of thyroid problems, it is recommended to include a thyroid function test during the female wellness checkup.
