Iodine, Serum/Plasma
Iodine (Serum/Plasma) measures the amount of iodine circulating in your blood at the time of your draw. Iodine is essential for making thyroid hormones (T4 and T3), so both low and high levels can affect energy, metabolism, temperature regulation, and overall thyroid function. This test is best interpreted alongside thyroid markers (like TSH, Free T4, and Free T3), symptoms, and supplement/diet history.
