Tested for IgG Antibody Food Allergies?

My 3 year old had a food allergy test specifically testing for IgG antibodies to foods. He came back with a long list of reactive foods. I am curious to hear if anybody else has had this specific test done for themselves or their children and what they noticed after eliminating these foods from their diets?

What can I do next?

So What Happened?

Went to the Allergist today and had the skin prick test done. Results were completely different and I'm more confused than ever. The only thing that showed up on the skin prick test was Walnuts. Walnuts didn't even register on the IgG test. Don't know what to do at this point. Thanks everyone for your thoughts.

I also had this test done on my son and he had quite a list of reactive foods as well - eggs, dairy, soy, wheat, and the odd thing like cantalope. I was told by the naturalpath that it can take up to 3 months for the body to entirely rid itself of the reactive food and the reaction it caused. I switched him from cow's milk to goat's milk and dramatically decreased the amount of dairy he consumed and his eczema was gone in two days. i've gradually been adding things back like different cheeses and yogurt and so far, no eczema. They can develop these allergies and outgrow them at any time so the only way to know is to do the elimination diet and then re-add. Due to the extensive list of foods and LONG time frame to cut them out, although it was recommended to cut out everything, we decided to only eliminate one reactive food at a time. He would have basically been on an Atkins diet with meat and fruits and vegetables and we didn't think that was healthy for a growing child. The reason I inially had the testing done was to try to figure out and deal with his chronic constipation after the medical testing road led no where. He didn't have any other symptoms or behavior issues, so honestly after all this, we didn't notice ANYTHING different with the constipation. The only thing that cleared up is the eczema. I think it totally depends on how its manifesting itself in the child and if the result isn't that severe then you have to take it with a grain of salt. As he gets older I think the constipation thing was more a holding issue because he didn't want to take the time to do it when he could be playing or whatever. Elimination diets are a hard thing for moms and kids to go through, so Good luck!

This might be a bit long, so bare with me.

My son right after his 1st birthday got sick and was not getting better. The doctor I had for him at the time would not listen so I switched doctors. They ran the allergy panel as well and it read that he was allergic to: Milk, Egg, Yolk, soy, peanuts, and dogs. He is now 4. We went to see an allergy specialist and had a skin test done, he was not allergic to Milk (he was lactose intolerent which we knew as soon as 1 week old) The skin test showed he was allergic to Egg whites and yolks, and dog was inconclusive due to his age. In conclusion he is not allergic to soy, peanuts, and out gre the intolerance to milk.

I hope my story has helped some.

IgE testing shows food allergies. IgG testing shows food sensitivities, these can be different. Removing foods that cause food sensitivities can make a huge difference for some kids. Defeat Autism Now doctors do IgG testing, Brain Balance does this testing, and typically chiropractors or nutritionists do IgG testing. I've never seen a mainstream doc do these tests though. Which lab did you use? Sometimes the results come with a sample diet. I'd suggest you remove the food for 2 weeks then introduce again and see the difference.

My granddaughter and my daughter both have had that test. They later both had skin prick tests to confirm the results. My granddaughter was a baby and only drinking formula. When my daughter switched her to a non-dairy formula, her eczema was better and she was less cranky. We never gave her the other foods to which she tested allergic. One was eggs, another peanuts. I don't remember the others.

When she was around 5 or so, her mother gave her scrambled eggs for breakfast and when there was no reaction continued to give her eggs. She had always eaten baked goods that contained eggs as well as cheese without having any sort of allergic reaction. She still eats eggs.

When my granddaughter was in the first grade the cafeteria gave her juice instead of milk. She took it upon herself to pick up the milk carton and started drinking the mild too. After several weeks she told her mother she was drinking the milk. Since she didn't have any obvious reaction we took her to the allergist who then used the skin prick test. Results were that the only food she was then allergic to was peanuts. She's still allergic to grasses and pollen. She had a severe reaction in the form of asthma to pollen this spring when she played in the piles of blossoms on the ground.

I strongly urge you to try removing, for several weeks, all the foods to which he tests allergic. What happens for him and what has happened for others may not be the same. Each of us has our own body chemical make up.

In an answer for a post asking about when to give peanut butter to their toddler, a mother answered that her daughter immediately reacted with major swelling including of her airway. They were fortunate to get her to the hospital in time to save her life.

I have numerous food allergies. My allergic reactions become increasingly more serious when I continue to eat a food to which I'm allergic. For example, I'm allergic to chocolate. I love chocolate and do eat it from time to time. The first day I have a few bites, I feel OK. The next day, my stomach feels a bit queasy. If I continue eating it I feel more and more nauseous to the point I have to stop eating it. I've never vomited but then I know when to stop. I do feel some concern every once in awhile because I could have a really serious reaction tho it's unlikely.

I'm also allergic to peanuts. I do not fool around with eating them. People have been known to go from a mild reaction one time to anaphylactic shock the next week or even year when they eat one peanut. Because I've lived for several decades with this allergy I'm not as conscientious about reading labels as perhaps I should be. We are conscientious to see that what we buy for my granddaughter does not contain peanuts.

Food allergies cause a lot of havoc in our bodies. They are not something to fool around with. What is wonderful is that often children outgrow their allergies when they start in early childhood. I do suspect, however, that if the child continues to eat the offending food it's possible that their body will build up an intolerance causing the allergy to continue. An allergist is the best person to ask about that.

My reaction to food allergies are two fold. Upset stomach and/or hives. I found that I feel noticeably better when I stay away from the foods to which I know I'm allergic and to the ones to which my body is intolerant. I'm no longer concerned about making a differentiation between the two. As an adult, I'm able to know how my body feels and judge the effects of certain foods. A toddler cannot do that tho you may notice a difference in the way he feels and thus behaves.

Also, it often takes several times of eating or not eating a food before you'll notice a difference. I hope the doctor told you how long you should wait before introducing or reintroducing the food.

A friend of mine had that issue with her little guy. He came back positive to almost everything. I remember there were only 4 foods he could eat for the longest time: green grapes & plain chicken and then pixie sticks and dumdum lollipops for snacks. It was heartbreaking. I believe he's now around 6 yrs old and is able to eat more foods, but he's still having a ton of issues :( Keeping you in prayers.
