I've never seen a T4 level that high & would like to know the reference range for normal T4 in your laboratory. I have seen very high TSH levels though&this would raise cholesterol while overactivity of the thyroid ( hyperthyroidism) has the opposite effect. If she's not experiencing symptoms, I don't think she needs emergency room evaluation but should get instructions from her physician first
