TSH Test (Thyroid-Stimulating Hormone)
Note: Fasting is not required for this test.
Our TSH blood test is used to help determine overall thyroid function by measuring levels of Thyroid Stimulating Hormone. Thyroid-stimulating hormone (TSH) is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH.
TSH stimulates the thyroid to produce thyroxine (T4) and ultimately triiodothyronine (T3). These hormones stimulate the metabolism of nearly every tissue in the body.
- An underactive thyroid is known as hypothyroidism. Hypothyroidism can cause symptoms of weight gain, tiredness, dry skin, constipation, the sensation of being too cold, and/or frequent menstrual periods. Hashimoto's thyroiditis is the most common cause of hypothyroidism.
- An overactive thyroid is known as hyperthyroidism. Hyperthyroidism can cause symptoms of weight loss, rapid heart rate, diarrhea, the sensation of feeling too hot, and/or irregular menstrual periods
