Thyroid Stimulating Hormone (TSH)


Add test

What is this test?

Thyroid Stimulating Hormone (TSH) controls thryoid gland activity and is typically used as a marker of thyroid health. TSH is not produced in your thyroid, but by the pituitary gland, a tiny organ the size of a pea found at the based of your brain. TSH however, acts directly on your thyroid and causes the thyroid to release its two hormones, T3 and T4, to help control your body’s metabolism (the rate at which your body uses energy).

The Thyroid Stimulating Hormone (TSH) test is done to find out whether your thyroid is working properly, or to determine whether your thyroid gland is underactive i.e. producing too little T3 and/or T4 (“hypothyroidism”), or overactive i.e. producing too much T3 and/or T4 (“hyperthyroidism”). TSH is also used to keep track of treatment with thyroid replacement medicine for hypothyroidism, and to monitor people who are treated with anti-thyroid medication for hyperthyroidism.
