Child with hypothyroid symptoms but blood work is fine?

[Nancie634]

My 10 year old male child has been exhibiting hypothyroid symptoms for about 4 years now.  He was a happy, active kid until he hit about age 7.  He began to become sluggish and was never really interested in doing anything active.  He sits around a lot and says that activities and exercise make him feel weak and his body aches when he tries to do these things.  He has frequent constipation.  His cholesterol is very high at 215.  He also has anxiety and concentration issues.  He has gained a significant amount of weight in the past 4 years, close to 65 pounds since 2012.  He has grown about 8 inches but has gained a large amount of weight in his belly and around his face mainly, under his chin.  He had thyroid blood work done in 2013 but everything came back normal.  He was just tested again and here are his results.  The reason I am posting these is because I want to make sure just because the lab says they are "normal", they actually are.  
His results:

Free Thyroxine Index: 2.4
T3 Uptake: 26
Thyroxine (T4): 9.4
Thyroid Peroxidase (Tpo) Ab: 7
Thyroglobulin Antibody <1.0

I do not see anything about a test for TSH.  All of the other blood work seems to be normal except his high cholesterol (215), Alkaline sulfates are low at 114 and his BUN/ Creatinine ratio is high at 28.  Not sure what is wrong but something is wrong with him and just trying to find answers.  Anyone who could let me know if these thyroid numbers look fine, please let me know.  Thank you.

In preparation for the appointment Tuesday, I am sending you a PM with some info that will be useful for you.  I highly recommend reading at least the first two pages of the paper linked within.  To access the PM, just click on your name and then from your personal page, click on messages.

I will also forward later any info on doctors in your area that have been recommended by other thyroid patients.

I currently live in Philadelphia very close to Bucks and Montgomery counties in Pennsylvania.  We are heading back to the doctor on Tuesday and we will be able to fully discuss the blood test results then.  I will see what the doctor says.  Child still sluggish and not losing any weight.

I would be very leery of a doctor that only ran those tests.  Free Thyroxine Index, T3 Uptake and Total T4 are outdated and not nearly as useful as those for the biologically active thyroid hormones, Free T4 and Free T3.   Although affected by many variables, TSH can help in the initial diagnosis, to distinguish between primary hypothyroidism, which was not present, and central hypothyroidism, which is a dysfunction in the hypothalamus/pituitary system.  You should go back and insist on testing for the latter three, and make sure they always test for Free T4 and Free T3 every time.  

As you proceed, keep in mind that a good thyroid doctor will treat a hypothyroid patient clinically by testing and adjusting Free T4 and free T3 as needed to relieve symptoms, without being constrained by resultant TSH levels.  Symptom relief should be all important, not just lab results.  

If you will tell us your location, perhaps we can suggest a doctor that has been recommended by other thyroid patients in the area.
