Thyroid Profile - III (FT3, FT4,
TSH)

What is a free T3 (FT3) test?
The free triiodothyronine (FT3) test, which is most commonly referred to as a T3 test, measures the level of a hormone called triiodothyronine in your blood. T3 is a hormone secreted by the thyroid glands and is very important for the metabolism of your body, including your heart rate and temperature. A T3 test is required in cases of symptoms like anxiety, weight loss, low tolerance for heat, and trouble sleeping. This test is often used to diagnose hyperthyroidism, a condition in which the body makes too many thyroid hormones. What is a free T4 test?
The free thyroxine test (FT4), often called a free T4 test, measures the quantity of free thyroxine in your blood. T4 circulates within the blood in two forms: free morpheme (FT4) and bound morpheme. Thyroxine (T4) is a hormone secreted by the thyroid and is important for growth and metabolism. The FT4 test helps to diagnose any suspected thyroid disease (hypothyroidism or hyperthyroidism) and check the treatment efficacy in people diagnosed with a thyroid condition.
A thyroid test in Bangalore is typically recommended if you have any conditions associated with thyroid gland dysfunction or to detect thyroid diseases such as hypothyroidism, hyperthyroidism, autoimmune disorders like Hashimoto's thyroiditis & Graves' disease, or goiter.
