What does Thyroid Profile Extended measure?
Contains 4 testsThyroxine - Free
A Thyroxine - Free test measures the free form of thyroxine (T4) hormone made by the thyroid gland. T4 hormone exists in the blood in two forms: bound (attached to proteins) and free (not attached to proteins). Most of the T4 hormone circulating in the blood is bound to proteins and only a small part is free. A delicate balance of bound and free T4 should be maintained to ensure the proper functioning of the body.

Thyroxine - Total
A Thyroxine - Total measures both the bound and unbound/free form of thyroxine (T4) hormone in the blood. T4 exists in the blood in two forms: bound (attached to proteins) and free (not attached to proteins). Most of the T4 circulating in the blood is bound to proteins and only a small part is free. It is necessary to maintain a fine balance of these forms to ensure the proper functioning of the body.

Interpreting Thyroid Profile Extended results
Interpretations
- If your TSH level is increased while the T3 and T4 are decreased, it usually indicates that you have hypothyroidism. Hashimoto’s thyroiditis is the most common cause of primary hypothyroidism
- If your TSH level is decreased but T3 and T4 are increased, it usually indicates hyperthyroidism. Grave’s disease, multi nodular goitre, toxic nodule are some of the common causes of hyperthyroidism
