Guest guest Posted August 24, 2010 Report Share Posted August 24, 2010 My insight – I don’t think I have much faith in the ‘immunologist’ testing and theories…… My understanding is that IgG’s register when the body is starting to build an allergy to a certain food/substance etc (but at the moment may be an intolerance). The IgA is when the immune system recognizes is building the antibodies and now responds to it as an allergy (most likely a permanent response to that food substance). ly I had all the celiac responses to wheat, and similar violent responses to soy and dairy – yet, apparently I registered a -0- IgA for soy, dairy, wheat, gluten (tested about 5 yrs ago), but did show high total IgG. My lame allergist said that the IgG really does not mean anything ….last time I saw him. It made no sense to me except that I was highly intolerant to these foods and was likely building a permanent allergy for all these. I really don’t think I am going to pay another $1200 out of pocket for an allergist to tell me that their tests are not accurate enough. I did genetic testing and I do not have the HLA’s for celiac, and I am not willing to go through a challenge to find out how sick I need to be to prove I should not eat these foods. Sound jaded?…..yeah. After years of MD’s failing to diagnose properly, all I really need to know is if it makes me ache, get a migraine, throw up, bloat or explode….don’t eat it!

Confusing?! The doctor who performed the IgG blood test which was positive said these are ‘latent’ allergies and because we have them there is a ‘leaky gut’. The immunologist who performed the skin test said the IgG test is not considered credible and that the skin testing and IgA allergy testing is actually more sensitive. Any insights on all of this???

Guest guest Posted August 24, 2010 Report Share Posted August 24, 2010 I'd go with the immunologist on this.

Guest guest Posted August 24, 2010 Report Share Posted August 24, 2010 Allergies are IgE mediated, not IgG.IgG pertains to autoimmune responses.Patients with IgA deficiency may not give accurate readings when performing autoimmune tests, therefore IgA levels are typically tested as well as IgG.This is a very complicated topic, and I certainly agree that if it makes you sick, don't eat it!On Aug 23, 2010, at 8:25 PM, Groff wrote: My insight – I don’t think I have much faith in the ‘immunologist’ testing and theories…… My understanding is that IgG’s register when the body is starting to build an allergy to a certain food/substance etc (but at the moment may be an intolerance).
