Am I Iga Deficient?

[LCL]

I just recently went to get tested for Celiac Disease. It looks as if my results are negative, but I want to know if I am IGA deficient.

Here are my results:

Endomysial Antibody IgA ----Negative

t-Transglutaminase (tTG) IgA--- <2 U/ml

Immunoglobulin A, Qn, Serum---- 133 mg/dL

Any help interpreting this would be greatly appreciated!

In order to correctly interpret test results, both the actual value and the reference range from the same lab are required.

As well as needing reference ranges to interpret the tests, usually abnormal results are marked as "low" on the lab slip. Was your total IgA marked as low?

Okay here is the lab's interpetation of the results:

Negative 0-3

Weak Positive 4-10

Positive >10

For the Immunoglobulin A, Qn, Serum Normal Range is 70-400

I also forgot to mention that I have Hashimoto's Thyroiditis Disease!

Thanks again for your help with the interpretation!

You are neither low IgA nor positive for celiac. Thing is, you can have negative test results and still have serious issues with gluten, plus the blood test only picks up celiac maybe 75% of the time. Hashimoto's is associated with gluten intolerance, so it's worth trying the diet.

For the Immunoglobulin G, just wondering, what is the Qn, Serum Normal Range?
