This is a pituitary hormone that stimulates the thyroid gland to produce its hormone. Sometimes the thyroid hormone is downregulated as the TSH is not enough to trigger the thyroid gland. The reference ranges of TSH for the normal patient are 0.5-4.7 mU/L.


T4 or the thyroxine is a storage hormone that itself cannot deliver to the cell. This is a popular thyroid test in Mumbai. They come to action through monodeiodination to get transformed into the active T3 form. There are two ways to determine the T4 level.

The free T4 is sometimes calculated which is regarded as the active thyroxine form. The normal level for free thyroxine is 0.8-1.8 ng/dL.


The T3 is the active form of thyroid hormone that is converted from thyroxine. There are three ways to determine the level.

Like the T4 the total T3 is measured to determine the level of active protein in the blood. The free T3 count takes account of the unbound T3 which is still active to get bound. While the reverse T3 is inactive proteins produced during stress.
