What Is Thyroid-Stimulating Hormone (TSH) Test ?

Q:

What is thyroid stimulating hormone test?

A:

A thyroid-stimulating hormone (TSH) test is actually a blood test. It measures the amount of thyroid-stimulating hormone in your blood. TSH is secreted by the pituitary, a gland located at the base of the brain. TSH is responsible for controlling the amount of hormones produced by the thyroid. Three primary hormone released by the thyroid gland are triiodothyronine (T3), thyroxine (T4) and calcitonin.

A TSH test is required to find out whether the thyroid gland is working the way it should. It can tell if your thyroid gland is overactive or underactive. In other words, you can find out whether you have hyperthyroidism or hypothyroidism with a THS test. Furthermore, this test can also detect a thyroid disorder before any relevant symptoms appear. If untreated, a thyroid disorder can cause health problems, so the test helps to prevent serious thyroid diseases.

As your TSH levels can fluctuate throughout the day, it’s best to do the test in the morning to get a more accurate result. It involves simply drawing some blood from your body. The blood sample will then be sent to a lab and analyzed there.
