My Son's Igg Is High And Iga Is Negative (or Deficient)?

Recommended Posts

Finally received blood test back from doc.

I posted earlier that my son has had gluten intolerance / celiac disease symptoms for over 6 mos. now

I've read about some people being IGA deficient. However, I can't find info. re: Total IgA values to determine deficiency.

In addtition, 2 IgA tests were performed by 2 different labs...why? Could one be the total IgA test?

Any information or advice would be helpful
