Normally, when your pituitary gland senses a decreased level of T3 and T4 in a blood, it releases TSH to cause the thyroid to release more of these hormones.

To help in the interpretation of the end result of the TSH blood determine, a physician usually requires or measurement of the variety of T3 and T4 in the meantime patient's blood. Thus, if the patient has unusually fat TSH but has low quantities of the T3 and T4 hormones and the other way round, it can be determined that it is thyroid problem. However, if both thyroid hormones and TSH are so high or both are far too low, then it is the pituitary gland this really diseased.
