This thyroid blood test package can help give you insights into your overall health.

The thyroid gland is located at the base of your neck and produces a hormone that influences every cell, tissue, and organ in the body. It may be small, but it can have a big impact on your health and wellbeing, influencing how fast your heart beats, how quickly your body burns calories and even your mood and fertility.

 

The Standard Thyroid Test measures both thyroid-stimulating hormone (TSH) and Free T4 (thyroxine) in your blood to assess thyroid function. It screens for specific thyroid health conditions such as underactive thyroid (hypothyroidism) and overactive thyroid (hyperthyroidism).

What's Tested
  • Thyroid Stimulating Hormone (TSH)

    Measures the levels of thyroid stimulating hormone (TSH) in the blood to evaluate thyroid function. TSH is a hormone produced by the pituitary gland and stimulates the thyroid gland to produce T4 (thyroxine) and T3 (triiodothyronine), two hormones that play critical roles in controlling the body’s metabolism.

  • Free T4 (Thyroxine)

    A hormone produced by the thyroid gland that is responsible for regulating body temperature, heart rate, and metabolism.

FAQ

  • Thyroid-stimulating hormone (TSH), produced by the pituitary gland in the brain, signals the thyroid gland in your neck to start producing thyroid (T3 and T4) hormones. These hormones control how your body converts food into energy (i.e., your metabolism). When these thyroid hormones get out of balance, they may cause a variety of health problems ranging from irregular heartbeat to anxiety or depression.6

  • If you have concerns about your thyroid health, it’s important to know the early warning signs of thyroid problems.

     

    Symptoms of hypothyroidism (an underactive thyroid) may include4:

    • Fatigue
    • Sensitivity to cold
    • Dry skin
    • Weight gain
    • Depression
    • Muscle weakness, aches, tenderness or stiffness
    • Irregular menstrual cycles
    • Constipation

        

     Symptoms of hyperthyroidism (an overactive thyroid) may include5:

    • Fast or irregular heartbeat
    • Moist skin
    • Tremors in the hands or fingers
    • Increase in appetite
    • Sweating
    • Nervousness, anxiety or irritability
    • Sensitivity to heat
    • Weight loss
    • Increased frequency of bowel movements

     

    Taking our Standard Thyroid Test can help you learn more about your body’s thyroid levels and whether you might have hypothyroidism or hyperthyroidism.

  • According to the American Thyroid Association, you should begin screening for thyroid dysfunction at age 35, and take follow-up tests every 5 years.7

  • You should take our Standard Thyroid Test if you have questions about your thyroid health or are experiencing early warning signs or symptoms of thyroid problems.

  • Low TSH and high T4 levels typically indicate an overactive thyroid (hyperthyroidism), suggesting that the thyroid gland is producing too much thyroid hormone. Common symptoms may include rapid heartbeat, weight loss, anxiety, and heat sensitivity.
     

    It’s important to consult with your healthcare provider for proper interpretation and potential follow-up testing or treatment.

  • High TSH levels often typically indicate an underactive thyroid (hypothyroidism). When the thyroid gland doesn't produce enough thyroid hormone, the pituitary gland responds by increasing TSH production to stimulate the thyroid. Common symptoms may include fatigue, weight gain, cold sensitivity, and depression. It’s important to consult with your healthcare provider for proper interpretation and potential follow-up testing or treatment.

  • Normal TSH levels vary by age.

    Consult with your healthcare provider if you have questions or concerns about your results.

  • Your testing will be performed in a CLIA-certified clinical laboratory. Labcorp provides leading-edge medical laboratory tests and services through a national network of primary clinical laboratories and specialty testing laboratories. Our labs perform regular quality assurance testing to ensure our results are accurate.

  • Your results will be provided to you through our secure online portal to view or print. Results are also made available through a secure portal to the independent healthcare provider who placed your test order.  If you are accessing your results through your Labcorp Patient™ account, all users linked to the account will have access to all OnDemand test results.
