TSI Present - So called "Negative"
I had posted previous about my 11 year old daughter and strange lab results. As I learn more about Thyroid Tests the more frustrated I'm getting with her Dr's.
Symptoms: She is an 11 year female does well in school not ADHD she is in the 18% - 19% for height and weight, has symptoms: Excessive sweating on the hands and feet, thicker arm hair, Irritable, sensitive (cries about EVERYTHING), Anxiety, very low pain tolerance, recent changes in vision one "Lazy Eye" - This eye is also slightly larger than the other, IBS, Frequent Bowel movements (3x/day), headaches, and shortness of breath. Thyroid does NOT appear to be enlarged.
Labs from ped endo aug 2011:
TSH: 3.53 ( .4 - 5.0 ),
FT4: 0.51 (1.1 -2.0) - Measured via Equilibrium Dialysis
Total T3: 166 (83 - 213),
Total T4: 15 (5.0 - 11.0),
thyroglobulin antibody was negative
thyroglobulin normal 22.8
Test results from our local Clinic Nov 2012:
Elevated FT4 1.89 (.58 - 1.64 ng/dl)
Normal FT3 4.02 (2.50 - 3.90 pg/mL)
Normal TSH 2.03; (.34 - 5.60 mIu/mL)
Thyroid binding globulin was normal at 21 (13-30)
Sorry for the lab re-post just wanted all the information together. In my last post it was suggested that I have her TSI and TPO also tested. The nurse called me back today and informed me that they DID run these tests back in June 2011:
TSI: 83 (<123)
TPO: .4 (0 - 9.0)
From my research I'm gathering that ANY TSI present suggests Hyper. They want to run a test on her for Thyroid Hormone Resistance. However I'm not sure now that this is needed. I think it would be hands down Hyper, but because the TSH isn't surpressed they want to call her thyroid function "normal", and suggested that we stop testing her thyroid.
So do I proceed with the test for THR, or is this the time to find a new Dr. for her and start over? Is it possible that the TSI present is blocking something that is preventing the TSH from being surpressed?
