How is a TSH level different from a thyroid level?

TSH. Tsh- thyroid stimulating hormone is released by the pituitary in response to low thyroid (t4) hormone levels. Tsh then causes more T4 to be released from the thyroid. High levels of T4 turn off the release of TSH in what is called a negative feedback loop. This process keeps thyroid levels relatively constant.
TSH vs T4 . Tsh stands for thyroid stimulating hormone. Tsh is secreted by the brain to cause the thyroid to secrete thyroid hormone (t4).

Not quite what it means! Some normal people have results outside the reference range. Some abnormal people have results inside the reference range. Numbers are just numbers, thus the doctor looks at the whole picture. Read more...
