    What Is a Free T4 (FT4) Test?

    The Free T4 (FT4) test measures the level of unbound thyroxine (T4) hormone in the blood. T4 is produced by the thyroid gland and plays a vital role in regulating metabolism and growth.

    This test specifically evaluates the free (biologically active) form of thyroxine, which is not bound to proteins and can directly affect body cells. It helps in diagnosing thyroid disorders such as hypothyroidism and hyperthyroidism, and in monitoring treatment effectiveness in patients with known thyroid conditions.

    Orange Health Labs provides convenient at-home sample collection for Free T4 tests across multiple cities, with rapid report delivery.

    Free T4 (FT4) Test Price

    The cost of the Free T4 test is generally around ₹350, though it may vary depending on the city where the order is placed. Prices include home collection.

    • Had an e-consultation at 8 pm, Doctor has prescribed few blood tests (incl Dengue). Orange Health Lab to the rescue. I found a 9:30 pm slot and surprisingly the phlebotomist reached much earlier at 8:45 pm, samples were collected & he left by 9, I got my CBC-Hemogram by 11:30 pm & Dengue report by 3 am. THEY ARE SO FAST & EFFICIENT. Also got a good discount on the otherwise expensive Dengue test. A BIG THANK YOU FROM THE DEPTH OF THE HEART šŸ™ Their whatsapp support is also quick & responsive.
