What is the Thyroid Stimulating Hormone Test?

Although you have the same habits, your weight has changed significantly; you always feel tired. You are always hot or cold but never comfortable. You did not have a regular period, but you are not pregnant, you have a bump on your neck.

If you experience any of these symptoms, it may be time for you to be checked with a Thyroid Stimulating Hormone (TSH) test.


What is TSH?

The TSH test is a blood test that measures the level of TSH in your blood. The pituitary gland in your brain makes a hormone called thyrotropin-releasing hormone (TRH), which stimulates the production of TSH by the pituitary gland.

This hormone tells the thyroid gland whether to speed up or slow down its production of T3 and T4. TSH is released into the bloodstream, where it travels throughout your body, stimulating the growth and activity of thyroid cells in your thyroid gland.

When too little thyroid hormone is in your body, your pituitary gland will produce more TSH. Conversely, if too much thyroid hormone is present in your body, your pituitary gland will produce less TSH.

What does a TSH test measure?

A TSH test measures how well your pituitary gland works by measuring how much TSH it releases into your bloodstream.

What is the purpose of the TSH test?

The primary purpose of this test is to help diagnose certain conditions such as:

  • hyperthyroidism (too much thyroid hormone)
  • hypothyroidism (too little thyroid hormone)
  • Hashimoto’s disease (an autoimmune disorder where antibodies attack the thyroid gland)
  • Goiter
  • Thyroid cancer

Why should I get a TSH test?

It may be beneficial for you to undergo this test if you have symptoms of thyroid disorders, such as weight changes, fatigue, feeling hot all the time (even if others around you are feeling cold), dry skin, hair loss, irregular periods, depression, and anxiety, constipation, and hoarseness.

These symptoms are not always caused by an underactive or overactive thyroid gland, so other tests may be needed before any treatment can be started.

How does the TSH test work?

The Thyroid stimulating hormone (TSH) test measures the level of this hormone in the blood. TSH is released by the pituitary gland, which is located at the base of the brain. The pituitary gland produces TSH in response to signals from the hypothalamus and the thyroid gland.

The hypothalamus is a small structure in the brain that plays a vital role in regulating body temperature, hunger, thirst, and emotions such as fear and anger. It also sends hormones to the pituitary gland to stimulate or inhibit its production of TSH.

The thyroid gland produces two hormones: T3 and T4 (thyroxine). These hormones are essential for normal development in children’s normal metabolism, growth, and development.

If you have low levels of T4 or T3 in your blood, this could mean that your thyroid isn’t working correctly. This test aims to find out if you have abnormal levels of these hormones; your doctor will want to check your TSH levels regularly to ensure they don’t get too high or low.

Taking certain medications like levothyroxine (Levothroid), methimazole (Tapazole), and propylthiour also affect how well your pituitary gland functions.
