    What is T3 - Free Test?

    The free triiodothyronine (Free T3) test measures the level of free T3 hormone in your blood, which is the active form of the hormone T3 that regulates important functions. T3 is produced by the thyroid gland and plays a crucial role in controlling energy use, metabolism, weight, heart rate, and even mood. Unlike total T3 tests that measure both bound and free T3, the free T3 test focuses solely on the hormone that is available for your body to use. This test is particularly helpful for diagnosing thyroid disorders and assessing how well your thyroid is functioning, as abnormal levels of free T3 can indicate issues such as hyperthyroidism (overactive thyroid) or other thyroid-related conditions.

    By opting for a Free T3 test in Bangalore, you can gain valuable insights into your thyroid health.

    T3 - Free Test Parameters

    An FT3 test measures only one parameter: the level of free T3 hormone present in the blood. T3 is a key thyroid hormone, which is crucial for regulating metabolism. Approximately 99.7% of T3 in the blood is bound to proteins, with only a small fraction remaining free and biologically active. The free T3 (FT3) test measures this unbound, active portion to assess thyroid function. There is a feedback loop between the pituitary gland, which produces TSH, and the thyroid hormones. When thyroid hormone (T3 and T4) levels drop, TSH rises to stimulate their production, and if thyroid hormone levels are too high, TSH decreases. The FT3 test is especially useful in diagnosing hyperthyroidism.

    T3 - Free Test Preparation

    There are several important factors you should consider before getting the Free T3 test in Bangalore:

    • Prerequisites: Fasting is not required before taking an FT3 test.

    • Best Time to Get Tested: You can get this test done at any time of the day.

    • Who Should Get a Free T3 Test: You may need an FT3 test if you show symptoms of hyperthyroidism. If you're on thyroid medication, you may need the FT3 test to check the effectiveness of the medicine. If you have abnormal TSH or T4, this test may be needed to check if you have hyperthyroidism.

    • Cautions Before Taking a Free T3 test: No special preparation is needed for the FT3 blood test. However, certain medications and supplements may affect test results. Your doctor will advise if any of these should be paused beforehand.
