When you go for additional test
s be sure to insist on Free T3 and Free T4, the biologically active thyroid
hormones (not the same as Total T3 and
Total T4). As Free T3 and
Free T4 levels drop toward the lower part of their ranges, hypo symptoms begin to become noticeable. Are you having any hypo symptoms yet?
One thing further, is that hypo patients are frequently too low in the ranges for Vitamin D, B12 and ferritin. So it would be a good idea to test
those as well.
