| | Complex Question obout TSH, T4, and T3 correlation
This is probably a complex question, but any oppinions I could get on it would be great. At age 12, I had a TSH of 7.45, low normal T4 and free t4, but high out of range T3, and free T3. I am now 20 years old, and have a TSH of 2.62, with low normal T4/t4free ( about the same as when I was 12) and my T3 and free T3 are now in the middle of the normal range. So my question is this, Why was my TSH so high when I was younger? I'm supposing it's because of the high T3, but if so, why haven't my T4 levels skyrocketed up since my TSH has gone back to normal levels now? I may be wrong, but isnt' T3 converted from T4 in other parts of the body other then the thyroid? could a problem lie there?
