Thyroid Panel-3 (Reflex) in Amritsar

Thyroid gland is an endocrine gland that produces thyroid hormones which carry out various energy related functions in the body. Normal production of these hormones is of utmost importance for the smooth  functioning of the body. TSH or thyroid stimulating hormone  signals the thyroid gland to produce the thyroid hormones. T3 and T4 are the thyroid hormones produced by these glands. Thyroid panel-3 is a comprehensive test that measures the functioning of the thyroid gland using the FT4 levels when the TSH levels are abnormal (Reflex testing)

The thyroid gland is an endocrine organ which produces vital hormones necessary for growth, metabolism, sleep, and sexual function. It is also responsible for your mood. Hormones, produced by the thyroid gland include triiodothyronine (T3) and thyroxine (T4), which are released in response to thyroid stimulating hormone (TSH), produced by the pituitary gland. TSH is what tells your thyroid gland to make more or less of T3 and T4. When insufficient TSH hormone is produced by the body, it indicates hyperthyroidism and when too much TSH is produced it indicates hypothyroidism. The interplay between T3, T4 and TSH is complex and varies between individuals. Thus, monitoring the levels of all three helps your doctor understand your thyroid function better. Here is all you need to know about the Thyroid Panel-3 (Reflex) test

What is the Thyroid Panel-3 (Reflex) test?

When a patient's TSH levels appear abnormal, a Thyroid Panel-3 reflex test is employed which further checks for free T4 (FT4) and free T3 (FT3) levels. Such a comprehensive test enables accurate measurement of thyroid gland activity. The results of these tests can help to diagnose or rule out hypothyroidism or hyperthyroidism.
