TSH levels higher than 4.5 mU/L usually indicate an underactive thyroid (hypothyroidism), and low TSH levels—below 0.4 mU/L—indicate an overactive thyroid (hyperthyroidism).1 However, there are exceptions to these interpretations and variations as to what a "normal" TSH level is. This is be...
A TSH blood test can be done quickly by health care professionals, and is used to identify abnormal hormone levels in the blood. Abnormal levels of thyroid-stimulating hormone might indicate a thyroid problem. High TSH levels typically indicate hypothyroidism, which means thethyroid glandis underacti...

Hypothyroidismis a disorder in which the thyroid gland does not produce enough thyroid hormones.

Pituitary production of TSH is measured by a method referred to as IRMA (immunoradiometric assay). Normally, low levels (less than 5 units) of TSH are sufficient to keep the normal thyroid gland functioning properly. When the thyroid gland becomes inefficient, such as in early hypothyroidism, ...
