Daughter's Anti Ttg Results - What Does This Mean?

[lovemyblessings]

My 7.5 year old daughter has been having stomach pain. She is quite tall for her age and very thin. She also has an IgG response to dairy, so our GI doc told me he was testing her for Celiac.

Here are the results as they pertain to Celiac:

Anti tTG IgA = 6

IgA (total?) = 92

What do these numbers make you think?

Every lab uses a different scale for measuring the results. It's hard to tell what those numbers mean without the reference ranges. Can you look at the results again and post the ranges? It will tell you what is positive, what is negative and what is in the equivocal range.

Unfortunately, the sheet faxed to me does not include the range. The tTG result does have an asterisk, indicating it is out of range. The IgA does not.

Makes me think some ding a ling office medical clerk didn't understand that you need the entire page of the lab report.

Try calling them back and sweet talking them into copying it the old fashioned way, or cutting and pasting it onto a file they can then copy, if they say they can't, tell them you paid for it, you own it, cough up the full results. Or go to the office and get a copy.

Anti tTG IgA = 6

IgA (total?) = 92

I called and was told that the reference range on the Anti tTG IgA is: less than 19=negative.

Based on that information, it doesn't seem likely that my daughter has Celiac, correct? I understand that only a biopsy can completely rule it out, but that number makes it unlikely, doesn't it?

Unfortunately, without knowing the reference ranges for the total IgA, you won't have a true picture of whether or not she is IgA deficient. If she is, the TtG IgA will not be accurate. In such a case, the doctor would have to rely on an IgG version of the TtG antibodies.

We can't say for sure if she has it or not (we are definitely not doctors). It is definitely possible to have celiac, but have a false negative bloodwork result. This becomes even more likely when the villi damage is less severe.
