TSH 3rd GEN-THYROID STIMULATING HORMONE

In primary Hypothyroidism, Thyrotropin (TSH) levels will be elevated. In primary Hyperthyroidism, TSH levels will be low. The ability to quantitate circulating levels of TSH is important in evaluating thyroid function. It is especially useful in the differential diagnosis of primary (thyroid) from secondary (pituitary) and tertiary (hypothalamus) hypothyroidism. In primary hypothyroidism, TSH levels are significantly elevated, while in secondary and tertiary hypothyroidism, TSH levels are low or normal. Elevated or low TSH in the context of normal free thyroxine is often referred to as subclinical hypo- or hyperthyroidism, respectively.

TSH Test is advised to for following analysis:

• Diagnosing an underactive or overactive thyroid gland
• Screening for thyroid disease before it causes symptoms (especially in newborns)
• Evaluation of a thyroid nodule, a lump on the thyroid gland
• Evaluation of a goiter, which is an enlargement of the thyroid gland
• Monitoring your response to treatment for hypothyroidism, hyperthyroidism, or another thyroid condition

If you have following symptoms, then TSH Test is advised:

• TSH (Thyroid Stimulating Hormone): TSH controls how much T3 and T4 the thyroid gland produces. TSH is an essential marker for the diagnosis and treatment of Thyroid disorders because elevated or decreased levels correspond to an underactive or overactive Thyroid, respectively.

The normal range of TSH is 0.5 to 5.0 mIU/L. Observations that can indicate Thyroid function abnormality:
 

TSH	Free T4	Total or Free T3	Thyroid Function
Normal	Normal	Normal	Normal Thyroid Function
Normal	Normal or Low	Normal or Low	Normal Thyroid Function
Normal	Low	Normal or High	Normal Thyroid Function
High	Low	Normal or Low	Primary Hypothyroidism
High	Normal	Normal	Subclinical Hypothyroidism
Low	High or Normal	High	Hyperthyroidism
Low	Normal	Normal	Subclinical hyperthyroidism
