THANK YOU - You answered my question about if my 11 year old needed to see a pediatric endo for elevated T4 and T3 but normal TSH. In your response you said we should check using a different lab. We had done this about 18 months ago at the pediatric endo. Lab results:
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
No follow-up was recommended from this appointment. Since then she developed some new symptoms (lazy eye and IBS). This is why I took her back into our local Dr. they ran her labs again, showing the elevated FT4 and FT3 but normal TSH - Our local lab does NOT run via equilibrium dialysis, and results have been VERY similar to the latest labs each time they have been run:
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)
We were sent back out to the pediatric endo last month - no labs were taken at this appointment, and they sent us home with the information on testing for THR.
She is an 11 year female does well in school not ADHD she 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, 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.
The pediatric endo is giving us the feeling that they think her body just naturally has a higher T4 level and no treatment is needed, and our local Dr. should stop testing her thyroid levels.
Should we run the Free T4 test via Equillibrium Dialysis again? I welcome ANY insight or advice!
