Thyroid Hormone Tests. Guide. Thyroid hormone tests are blood tests that check how well the thyroid gland is working. The thyroid gland makes hormones that regulate the way the body uses energy. The thyroid gland is a butterfly-shaped gland that lies in front of your windpipe (trachea), just below your voice box (larynx).
When the thyroid hormone levels are low, weight gain, dry skin and constipation are some of the symptoms. The TSH blood test is usually ordered to diagnose a thyroid disorder. It can also be used to monitor the effects of thyroid replacement therapy. Newborns are screened for an underactive thyroid with the TSH blood test. The TSH blood test involves taking a blood sample from the arm with a needle. For newborn screening, the sample is taken from the heel with a needle prick. No preparation is required for the test, but several things can affect the TSH level. Aspirin and thyroid-replacement therapy drugs will affect the test.
