Why is the Test Done?

This is a blood test that measures your level of thyroid stimulating hormone (TSH). Health care providers use this test to diagnose problems affecting the thyroid. The thyroid is a butterfly-shaped gland located near the base of your throat above your collarbones. The thyroid makes two hormones, T3 and T4, that affect your energy levels, mood, weight, and other important parts of your health. The pituitary gland in your brain makes a chemical called TSH, which triggers your thyroid to make T3 and T4. When your pituitary gland produces too much or too little TSH, this can cause your thyroid to be overactive (hyperthyroidism) or underactive (hypothyroidism). Low TSH may mean you have hyperthyroidism, and high TSH can mean hypothyroidism. The results of other thyroid tests can help to determine the cause. The test requires a blood sample, which is drawn through a needle from a vein in your arm.


How to prepare for the Test:

No medicine to be taken before the test unless specified by the referring doctor
