By releasing these three hormones, the thyroid controls various functions of the body, including metabolism and growth.. In general, the TSH test is performed to determine the following: - Determining the main cause of abnormal thyroid hormone levels - Screening and diagnosis of hypothyroidism or hyperthyroidism - Diagnosing the correct functioning of the thyroid gland ### **normal TSH level** The normal range of TSH in the blood should be between 0.4 and 4.0 mg international units per liter. In people being treated for thyroid disorders, this value is between 0.5 and 3.3 mg. Abnormal TSH levels include: 1... TSH value higher than normal usually indicates hypothyroidism....

This condition is called hyperthyroidism or hyperthyroidism. It should be noted that various conditions, including Graves' disease and thyroid nodules, lead to hyperthyroidism. A non-functioning pituitary adenoma can lead to low TSH levels as well as low thyroid hormone levels. #### **Symptoms of Low TSH** A low TSH level is usually a sign of hyperthyroidism.
