Need help with son's blood test results

[currier54]

My son just recently got tested for celiac disease - he's 12, but has dropped down to the 5th percentile for weight and has gotten frequent canker sores in his mouth for years, and the last few months has been getting little itchy rash-like patches on his arms, face, etc

I don't have an official diagnosis (long story, and seeing how gluten affects me I'm not willing to go through what's necessary to get one at this point), but the fact that I may have celiac disease has made me suspicious about my kids possibly having it. 

It looks like, from the results, that they tested his IgA and it was 173 (normal range = 81-252), and his TtG IgA and it was <2 U/mL (normal range = 0-3).  Is this sufficient to rule it out, then?

Thanks!

No, get the itchy rash biopsied.  It may be Dermatitis Herpetiformis, a skin rash the occurs with Celiac Disease.

Sores around the mouth can indicate deficiencies in several B vitamins.  Get his B vitamins and his Vitamin D level checked, too.

Hope this helps.
