Tri-Iodothyronine Free (FT3)

Tri-Iodothyronine Free (FT3), in Bangalore
Measures the active free T3 hormone in blood to evaluate thyroid activity and guide diagnosis or treatment.
What is a Tri-Iodothyronine Free (FT3) Test in Bangalore ?
The Free Tri-Iodothyronine (FT3) test measures the portion of the thyroid hormone T3 that is not bound to proteins in the blood. Free T3 is the active hormone that helps control metabolism, energy, heart rate, and body temperature. Measuring FT3 helps detect overactive thyroid (hyperthyroidism) and can help evaluate treatment response. Doctors use FT3 together with TSH and free T4 to diagnose thyroid problems, to clarify unclear results, and to adjust medication doses. It can also help assess effects of illness, certain drugs, or pituitary disorders on thyroid function.

Why Take a Tri-Iodothyronine Free (FT3) Test in Bangalore ?
FT3 is often ordered as part of a thyroid function panel with TSH and free T4. Your doctor may request it if you have symptoms such as unexplained weight change, fatigue, palpitations, temperature sensitivity, or a neck lump. It helps diagnose and monitor thyroid conditions like hyperthyroidism and can guide medication dosing. Abnormal results may be caused by illness, pregnancy, medications, or autoimmune thyroid disease, and family history of thyroid problems can make testing more important.
