4 year old with abnormal thyroid testing.

My daughter from birth has always had a low weight.  At birth she was 6.2lbs and struggled to gain weight.  Today at 4 1/2 years of age she is barely 35lbs.  I have always been concerned about her weight but her doctor said she is following her own curve.

Earlier this year from feb to june had severe diarrhea, vomiting and so on. In June I finally went and got a second opinion, because her first dr said it was just a stomach virus. I had taken her in a lot during those 4 months.  

Well the second opinion, took a stomach x-ray and A full thyroid panel TSH, Free T4, Free T3, TPO-Ab and Tg-Ab.  Her numbers came back low so they did the test again.  Still came back just under the norm, so they wanted her to repeat the test in three months.  The stomach x-ray showed a blockage of her bowels, so we used a softener and it did the trick.  She bounced back and has been healthy since.  

Saturday we went to the hospital to do the three month repeat.  One vial of blood they used to test the T4, it came back low.  The other vial of blood clotted before they could do the other tests so we are going back tonight to redo the whole panel again.  

My ? is what does it mean that the T4 test came back low again. Does this mean she has hyper or hypothyroidism.

Low T4 suggests hypo -- I would suggest a pediatric endocrine eval, esp with her relatively low weight and her symptoms.  Not sure I would want to wait 3 months if it were my family member, but I may not have all the details.

I would definitely get her into a *pediatric* endocrinologist.  I'm finding out with my son that there are a lot of metabolic things that can be caught early and treated more successfully - especially if there is something with her autoimmune system.  They can check for antibodies which may be affecting her thyroid, pancreas, etc.

Do you have a pediatric hospital nearby that you could get a referral from?  If not, call around and ask for recommendations.

Good luck.
