The problems with TSH tests are; they are made for medication; type Synthyroid.
"Not only are patients with OBVIOUS hypothyroid symptoms being told they have no thyroid problem because of a “normal” TSH (i.e. a TSH number in range), they are being held hostage to the TSH range when on thyroid medications, EVEN THOUGH the patient continues to have typical hypothyroid symptoms while in the range.
WHAT IS THE TSH??? In your body, the Thyroid Stimulating Hormone (TSH) is synthesized and secreted by your pituitary gland…i.e. it’s a PITUITARY hormone, NOT a thyroid hormone. You can view the TSH like a messenger sent to knock on the door of the thyroid. And its purpose is to regulate your thyroid gland–to tell it to produce more, or to tell it to produce less. In a healthy individual, its message is based on whether your blood levels have too little thyroid hormones to meet the demands of your body, or too much.
When the thyroid gland becomes diseased or disabled and fails to do its job adequately (called hypothyroid), the TSH knocks and knocks on the door, and theoretically, the TSH lab will show a high number. Or, if the thyroid gland gets on its exercise bicycle and overproduces thyroid hormones (called hyperthyroid), the TSH lab will theoretically go low to show that the TSH in your body isn’t knocking."
An option is to do the Barnes test; this way you can easily monitor your body temperature, see the spikes, and downs, know when it feels good, and adjust the Iodine accordingly.
