We do not know all the ins and outs of interpretting lab data — so we don’t do it. The thyroid does make approximately 20% of the T3 that the body uses; the rest is created by the conversion of T4 into T3 in other body organs. Sometimes, an individual can have an overabundanc of T3, and be hyperthyroid as a result. I do not know the why of it, just that I’ve read that it occurs. Since T3 is the most potent form of thyroid hormone, however.

The TSH lags because it is sort of a “moving average” of our actual thyroid hormone levels. If your T3 is just moving into the normal zone, or still slightly higher than it should be, that might explain why your TSH is still in the “hyper” zone.

I hope this helps, sketchy though it is.

Hi all I was reading the lab results chapter in the Graves disease in our own words book and saw that your TSH level lags behind the T4 and T3 levels as far as normalizing which is exactly what mine show my tsh has stayed exactly the same but my other levels have come within normal range, my question is how long does it lag? Also even though my T4 and T3 totals showed normal range the T4 was bordeline too low now and the T3 was borderline too high how can that be? I thought T4 converted to T3 so how can it be almost too low and then the T3 be on high end of normal like 2 pts away from high? My Gp does not want to see me until december so that is why im asking. I just like to know what is going on with my body it somehow makes me feel better about all of this.

thanks all
