High Igg Test - What Next?

[Pal Mom]

My daughter is 6 years old. She was born 8 weeks premature, but was born relatively healthy and has met all "normal" milestones throughout her six years.

She always complains of her tummy hurting and she suffers from constipation and occasional leg cramping (related?!). Her doctor ran several tests. The IgG test results came back high.

I have not heard from her doctor yet regarding these tests (they were emailed from the lab), so I am hoping to gather a little bit of information about them before she calls. Does the high IgG test mean she should have other tests done? I have read about a biopsy? Is it too soon to consider something like that or is that the next step? All the other tests were normal, with the exception of her free T4 test. The result for free T4 was slightly high. Two of her test results are below.

Antigliadin IgA Antibody = 3

Unit: U/mL

Reference Range:

NEGATIVE: <11

EQUIVOCAL: 11-17

POSITIVE: >17

Antigliadin IgG Antibody = 90

Unit: U/mL

Reference Range:

NEGATIVE: <11

EQUIVOCAL: 11-17

POSITIVE: >17

She should have been tested for total IgA and TTG IgA as part of a celiac panel. How did those look? Celiac is not diagnosed from anti-gliadin IgG unless the person is IgA deficient overall.

It does mean she might be sensitive to gluten, but don't try the diet until all the testing is done. The gluten-free diet makes the tests inaccurate.

Here are two of her other tests. They were both in the normal range. I had heard that IgA might be low in children. Is that correct?

TTG IgA Antibody = <3

Unit: U/mL

Reference Range:

NEGATIVE: <5

EQUIVOCAL: 5-8

POSITIVE: >8

IgA = 69

28-180 mg/dL

Here is information on the IgG with normal IgA. Basically it's not a celiac result.

Let your doctor finish ruling out other problems, and decide whether he wants to do an endoscopy. He may want to have a look anyway. Once the testing is done, you can try the gluten-free diet and also screen her for other food allergies.

Skylark,

Thank you for that link. One of my tests keeps coming back high dispite the gluten-free diet. Once I look back at my records, I'll be able to use that site to help me figure out what else to request testing for.

I realize this thread is old but I was wondering if you found out what was wrong with your child? My 2 year old has the same symptoms and high igg
