When testing thyroid levels, it is important to run a blood test that includes a FULL thyroid panel of 9 or 10 different markers. Most conventional medicine doctors will only run a few thyroid markers to determine the type and dosage of thyroid replacement hormone prescribed. It is very important to maintain adequate thyroid hormone levels at all times. However, be aware that thyroid replacement hormone prescriptions do not address the root cause of Hashimoto’s Autoimmunity or Hypothyroidism, which is why dosages often have to be checked, modified and ultimately increased. In order to address the root cause of thyroid disturbances, a functional medicine specialist will order a full thyroid with up to 10 thyroid markers. These additional holistic markers help determine thyroid imbalances due to brain/thyroid signaling, gut or liver dysfunction, hormone under/over-conversion and more.
