Thyroxine (Total T4)
T4 is the main hormone produced by the thyroid gland. It circulates in blood and gets converted to the active form T3 when needed.
Unit: mcg/dL
High T4 suggests hyperthyroidism. Can also be elevated during pregnancy or with birth control pills (due to increased binding proteins).
Low T4 confirms hypothyroidism. The thyroid isn't producing enough hormone. Common in India, especially in women.
