Free thyroxine (T4L)
Free thyroxine (T4L) is the unbound, active form of the T4 hormone produced by the thyroid gland. T4 is converted to T3 in tissues and regulates metabolism, growth, and development. Free T4 levels are essential for assessing thyroid function and monitoring thyroid balance.

Thyroid-Stimulating Hormone (TSH)
Thyroid-Stimulating Hormone (TSH) is a hormone produced by the pituitary gland that regulates the production of thyroid hormones (thyroxine [T4] and triiodothyronine [T3]) by the thyroid gland. It acts as a feedback mechanism to ensure proper thyroid function
Free triiodothyronine (T3L)
Free triiodothyronine (T3L) is the active, unbound form of T3 hormone available to tissues. T3 is the most metabolically active thyroid hormone, regulating metabolism, heart rate, and body temperature. Free T3 levels help assess thyroid function and hormonal balance.
Ioduria
Ioduria measures iodine levels in urine, reflecting recent iodine intake and thyroid function status. Adequate iodine is essential for thyroid hormone production. Low levels may indicate iodine deficiency and risk of thyroid dysfunction, while high levels can suggest excessive intake or thyroid disorders.
