TSH
Alternate Names : Thyroid-Stimulating Hormone, Thyrotropin
What do the test results mean?
The normal concentrations of TSH in blood
range from 0.2 to 4.7 mcU/mL.
Abnormally high levels of TSH may indicate the following:
cretinism, or arrested physical and mental development
primary hypothyroidism, or decreased function of the thyroid caused by problems within the thyroid
secondary hypothyroidism, or decreased functioning of the thyroid caused by problems in other organs
thyroiditis, or inflammation of the thyroid
Abnormally low levels of TSH may indicate hyperthyroidism, which is an overactive thyroid gland. A low level is also seen with hypopituitarism, which is an underactive pituitary
gland.
