It's important to understand the meaning and possible causes of both high thyroid stimulating hormone TSH and low TSH, whether you have been living with thyroid disease for a long time or are only having the test to screen for a thyroid disorder. A high TSH level can mean a new diagnosis of hypothyroidism or inadequate thyroid replacement. A low TSH might mean hyperthyroidism or overtreatment of hypothyroidism. That said, there are exceptions to these interpretations, as well as what a "normal" level may be for you. TSH levels are confusing and not necessarily intuitive.
TSH is produced by the pituitary gland, which is located at the base of your brain. The thyroid is small, butterfly-shaped gland located in the front of the neck. The thyroid controls numerous different bodily functions, including metabolism and growth, through the release of these three hormones. Your thyroid will produce more hormones if your pituitary gland produces more TSH. In this way, the two glands work together to make sure the right amount of thyroid hormones are produced. However, when this system is disrupted, your thyroid can produce either too many or too few hormones. A TSH test is often performed to determine the underlying cause of abnormal thyroid hormone levels.
The thyroid is a gland located in the neck. It's job is to take iodine from the blood and combine it with an amino acid one of the building blocks of protein to form thyroid hormones. One of the hormones, thyroxine, is responsible for your metabolism. Thyroid function tests help to determine if your thyroid is not working correctly:. Abnormal thyroid function is common. It is seen in two to three percent of the entire population. When the thyroid is not working properly, it can cause changes in other blood tests as well.
This article explores what your levels should be and how it relates to hypothyroidism. Below this box is a contents menu to help you navigate directly to a particular section. TSH is a hormone that controls thyroid function. It stands for Thyroid Stimulating Hormone. Once the thyroid stimulating hormone makes its way to your thyroid, levels are largely dictated by the amount of T3 and T4 in your blood. But when T3 and T4 levels are high, the body produces less 2.

Serum TSH assessment is the most sensitive screening test for the diagnosis of thyroid dysfunction in the absence of pituitary or hypothalamic disease. This test has been used increasingly in the last decade to detect subclinical thyroid dysfunction STD. Recent data suggest that STD is a common disorder that may be associated with important adverse events 1 — 5. The treatment of mild thyroid hormone excess TSH 0. However, what is the normal TSH reference range? Obviously, this issue is critical in deciding whether or not to treat patients with mild STD and in identifying individuals with high-normal or low-normal serum TSH. It is also important in defining the TSH target level in patients receiving thyroid hormone replacement therapy.

TSH (Thyroid Stimulating Hormone) Test
Thyroid-stimulating hormone TSH is produced by your pituitary gland, which helps regulate hormone production and metabolism throughout your body. TSH helps your thyroid gland make other hormones essential to your metabolism, such as thyroxine. It also contributes to your overall energy levels, nerve functions, and much more. The typical range of reference for TSH levels is anywhere between 0. A recent study suggests that the normal range should be more like 0.
