normal value vary from 0.5 to 5.

.The best way to initially test thyroid function is to measure the TSH level
in a blood sample.
A high TSH level indicates that the thyroid gland is failing because of a problem that is directly affecting the thyroid (primary hypothyroidism
The opposite situation, in which the TSH level is low, usually indicates that the person has an overactive thyroid that is producing too much thyroid hormone (hyperthyroidism
Occasionally, a low TSH may result from an abnormality in the pituitary gland
, which prevents it from making enough TSH to stimulate the thyroid (secondary hypothyroidism).
In most healthy individuals, a normal TSH value means that the thyroid is functioning normally
u need not to worry
