TSH – RT3 -T4- T3 Contradictions
Depending upon the combinations of several factors, TSH can be an accurate or inaccurate measure of the body’s true need for thyroid hormones. TSH can only be interpreted when the T4, T3 and RT3 are considered. Therefore TSH is a secondary value and can/should not be used to adjust thyroid hormone levels. However, it can serve as a subjective measure of iodine intake, stress, and pituitary and hypothalamic function.
