TSH is a hormone made in the pituitary gland that tells the thyroid how much T4 and T3 to make. A high TSH level most often means you have hypothyroidism, or an underactive thyroid. This means that your thyroid isn’t making enough hormone. As a result, the pituitary keeps making and releasing TSH into your blood. A low TSH level usually means you have hyperthyroidism, or an overactive thyroid. This means that your thyroid is making too much hormone, so the pituitary stops making and releasing TSH into your blood. If the TSH test results are not normal, you will need at least one other test to help find the cause of the problem.
