    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.

He ensured that all the medical kits are new and even showed it to me before using. I would definitely recommend my family and friends for any future tests. Thank you Dhanraj for making sample collection easy and professional.

    • My experience with Orange labs have been excellent so far. Have relied on their home visit for regular blood tests given that it is a case of dengue, and close monitoring of the blood count is essential. They are prompt as promised and the results too are available within committed time lines. As to accuracy of results, I rely on the lab certifications to give me confidence. Would have wanted a voice interface ( a number to call ) for a first time experience, and an ability to order for quicker reports (2 hours) for a differential charge. For the service delivered as published, it is a 5-star
