Delayed reaction and immediate reaction

[CSP]

OK... my question is... If the IgE (immediate reaction) test came up with a reaction of Garbanzo bean, wouldn't the IgG (delayed reaction) have garbanzo bean as reactive too?

 

My son shows clinically insignificant on the IgG for GB, but a class 5 on the IgE for GB? How can he be reactive on the immediate and not the delayed?

 

I'm confussed beause he is off the charts for peanut on both tests.

 

If anyone has an answer for this let me know, I'm not sure if I can use GB for my son's new gluten free diet.

 

Thanks,

C.P.
