The body increases TSH to stimulate production of thyroglobulin which is
used to bind to the iodine in thyroid hormone production. Individuals can have TSH levels as
high as 75 for up to 6 months without clinical signs of hypothyroidism. The best values to check
with labs if there is a concern are the Free T3 and Free T4. You will find in most cases that the
“frees” are nicely within the ranges.
Basically they give TSH to patients to facilitate iodine absorption into the thyroid. So the iodine hungry thyroid is secreting more TSH to help uptake.
