Positives that were highest (over the amount they bother to count) were Candidas, Cladosporium (have a colony out on the porch of those), Fusarium, and Stemphylium(?). Aspergillus was positive but not high positive...happy about that! However I had equally high number of antibodies to egg whites and other foods to a lesser extent, due to leaky gut!!! Weird. I did have some doubt as to whether leaky gut actually existed but now that I see my blood has antibodies to food in it, it's a little more real. --------------------------------- gets better.

Guest guest Posted June 25, 2006 Report Share Posted June 25, 2006 I've heard the blood test for allergies can reveal some allergic reactions that don't show up right away, delayed, as opposed to skin tests that ONLY show immediate response. Perhaps that is what you are thinking of, but that is the IgE portion of the test. The IgG is definately not allergy but antibody. I have Epstein Barr Virus. I get retested every six months. My tests are IgG and IgM. My IgG are very high. I'm sure it doesn't mean I'm allergic to EBV. IgE is not done. IgM is negative. IgM is a first responder antibody, that attacks new infections, and so negative IgM means it is not new infection and I'm not in acute, contagious stage. Other things are tested too, an NA/AB and EA/AB which are both high also. Anyway, point is that IgG is not an allergy test. None of the IgG and IgE were the same probably because one was testing allergens and other was testing antibodies. Antibodies to food would mean you have undigested food seeping into your blood stream that shouldn't be there. Allergens indicate you are allergic to that food. If sometimes you have allergens and sometimes you don't could be because you have avoided food and so allergens present. Same with antibodies, except you would probably still have 'some' just not high I would imagine since your body usually keeps antibodies to protect you in future. > > The igg shows delayed sensitivies and the ige type shows more immediate allergen response.

Guest guest Posted June 25, 2006 Report Share Posted June 25, 2006 Leigh, after rereading your post there is some confusion as to what test you are describing. IgG and IgE are blood tests so skill of skin testor wouldn't be a factor. Skin tests I have heard show only immediate response to allergen but blood tests should show both things your body react to immediately and also delayed, so skin tests don't show things that you may react to in delayed fashion. My doctor said skin test also react to many things that are not the allergen being tested. Some people just have sensitive skin and react to being pricked or punctured, some are reacting to the other substances in the test material, there is more than just allergens being put on skin. Some places go to great lengths to make sure allergen is pure and there is nothing else that a person could react to, are sterile, etc too. I know Dallas Center does that. So were you having skin tests or blood tests? Skin tests show only immediate response, blood test is only way to include in things that may have a delayed response. According to doctor I went to skin tests shouldn't be used at all to test for allergies as there are too many false positives. Blood tests should show everything (you have been exposed to in the recent past). If you have never been exposed to it, you won't have allergen to it present. You could argue then that since skin tests introduces allergen, it would detect an allergy to something you have not come in contact with. However skin allergy tests only test 'common' allergens so it is extremely unlikely you would not have recently exposed to most allergens used in skin tests (i.e. peanuts, milk, corn, molds, grass, trees, cat, dog, etc), but it's possible. > > The igg shows delayed sensitivies and the ige type shows more immediate allergen response.

Guest guest Posted June 25, 2006 Report Share Posted June 25, 2006 Leigh, as unbelievable as this may sound, many doctors including allergist don't understand leaky gut so they assume IgG is some sort of 'autoimmune' response to food, but I'd ask your doctor again, are IgG antibodies or allergens. I think he will say they are antibodies. Here is quote from link 'who' just posted today on MCS and it mentions IgE as indicating allergies. It says nothing about an allergy connection to IgG. A good allergist will run IgE and IgG so as to separate an allergic response from an immune response. For example if you are having trouble with mold, is it allergy problem= IgE response or mold/fungal infection= IgG response. They do this to figure that out. Here is quote from 'who's article on MCS/ Multiple Chemical Sensitivity syndrome: " Nor is MCS a true allergy because there are no IgE-mediated reactions involved, so allergists don't know what to make of it. " From> http://www.cqs.com/mcs.htm > > barb--lack of consistent skin testing led me to get ige and igg blood tests for food, inhalants, and molds. leigh > Quote Link to comment Share on other sites More sharing options...
