I can not get the lab to tell me if this is adult range or the results are based on her age of 14 years.
I am concerned that if I have further tests the fact that she is now on BCP will not give a clear answer.
O.k. Though her TSH is very normal and looks very optimal the other levels are indicating there may be a problem. The dr is most likely looking only at the TSH and the fact that the other levels with exception of the T3 uptake are "in range".
The TSH is a pituitary response. So when other levels are off it does indicate that the TSH is not yet caught up to the problem and is showing all to be well. The FT4 is low in the range. This is where most people will experience hypo type symptoms. The Ft4 should be more at 1.11 and above. The FTI which is the calculation is above the mid range, but again it is a calculation and not as accurate or telling as the actual Ft4 and FT3 would be. The T4 total is also below mid range. This does indicate as well that the FT4 would be low, which it is.
I would suggest that you get antibody tesing done. She may have an autoimmune condition called hashi's. It is very common and treatable.
Does she have any other symptoms other than the problems with her cycle? Problems with the cycle are associated with thyroid problems, but there are many many other symptoms as well. Is she experiencing any others? There are many that you wouldn't even think are thyroid related but can be.
