its the total t4, but i have heard all different ranges
The lab that ran the test sets the range, and those can vary. A typical range for total T4 would be about 5-12 µ/dL. So, yours would be high. Ordinarily, high T4 indicates hypERthyroidism, not hypO. But your result means little, because that test has a considerable error rate and would be influenced by estrogen-containing birth control, among other things. Get your MD to run the free
T4 test instead of total T4.
Other valuable tests would be free
T3 and the thyroid antibodies against TPO and Tg.
