IgA Deficiency?

[Jms60014]

I am in the process of getting tested for celiac and received my Immunoglobulin A blood test results back through my online chart.  I have not spoken with my doctor yet.  Those results are:

 

Immunoglobulin A 79 mg/dL, standard range 100 - 490 mg/dL

 

This is the second IgA test that came back slightly under the standard range.  Does this mean I am IgA deficient?

I am not a doctor, it yes, it appears that you are IGA deficient.  In terms of diagnosing celiac disease, that means that the IGA celiac tests that were run would be invalid.   Your doctor would need to run the IGG versions (hopefully he ran them all or you have to go back in for another draw).  So, if you get a negative on the celiac IGA tests   (TTg and DGP), you could still have celiac disease.

Ditto.  That's a low IgA, more commonly found among celiacs, so make sure the doctor uses IgG basaed tests (DGP IgG, tTG IgG, EMA IgG, and maybe the older AGA IgG.

Best wishes.

Thank you for the replies.  My doctor did run a full panel,  but wasn't expecting anything stellar since I have been gluten free since July.  She is waiting to get the genetic testing results back before we take the next step in testing,  possibly a gluten challenge. I have full faith in her, as she is at the University of Chicago Celiac Center.

I am very new to this and still learning.  I wasn't sure if the result had to be a certain amount below the standard range to be considered iga deficient.

You are in good hands at the University of Chicago!
