Thyroid Stimulating Hormone (TSH) Test

$ 49.0

Testing your hormones starts with a simple TSH blood test.

Your thyroid is essential to your overall health and wellbeing. Thyroid hormones influence everything from your heart rate to how quickly your body burns calories. They can also influence factors as subtle as your mood or as vital as your fertility.

This TSH blood test measures thyroid stimulating hormone (TSH), which stimulates the thyroid to produce two additional hormones, T4 (thyroxine) and T3 (triiodothyronine), both of which play a critical role in controlling the body’s metabolism. Typically, low or high TSH levels indicate potential problems related to the function of your thyroid.

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.

  • Thyroid-stimulating hormone (TSH), produced by the pituitary gland in the brain, signals the thyroid gland 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.3

  • High TSH levels most often occur when the thyroid gland produces too little thyroid hormone (hypothyroidism).

    Low TSH levels most often result from the thyroid gland producing too much thyroid hormone (hyperthyroidism).3

  • If you have concerns about your thyroid health, it’s important to find out if your TSH levels are within normal range. Taking our TSH test can help you know more about your body’s thyroid levels and whether you might have hypothyroidism or hyperthyroidism.
