What is Thyroxine (T4)?
Thyroxine (T4) is one of the primary hormones produced by the thyroid gland. It contains four iodine atoms and is released in larger quantities than T3. Since T4 plays a key role in maintaining several essential body functions, monitoring its level is important. This test, either alone or along with T3 and TSH, helps in identifying thyroid-related conditions.
Free T4 (FT4) refers to the portion of T4 that is not attached to proteins and is directly involved in regulating thyroid activity. Low FT4 levels usually suggest hypothyroidism, while high FT4 levels may indicate hyperthyroidism. You can book a Free Thyroxine test at an affordable cost with convenient home sample collection.
