Just curious if anyone here has had the ELISA testing done, and if it was helpful or not.
I keep getting so close to finding the answer to my health problems, and I am still convinced it is food related...just looking for a means to find some real answers.
Is it accurate? Is it helpful?
Also, is it something my GP could do or do I need to go to an allergy specialist?
Thanks!

I had the skin prick test for 98 foods. The test came back with no reactions. I clearly react badly to wheat(gluten) and soy, so my Dr. did a RAST (blood test) and I didn't have any reactions.

I was told there isn't any reliable test for food intolerances, other than your personal experience of symptoms when you consume something that doesn't agree with you. The best way of figuring those out is to keep a log of everything you eat, and note any symptoms you have. Unfortunately many food reactions are delayed, making it a bit tricky to figure out at first.

That being said, some people do food sensitivity testing through Enterolabs via mail order and feel it helps them know what foods to avoid or challenge later. It's been noted that there can be a lot of false positives with this test, which makes it a bit unreliable, which is why Dr.s don't usually order it.

Ya, that's what I was afraid of.
I am having the hardest time pinpointing anything...especially because I am almost positive whatever it is has a significant delay with reactions.
I recently started keeping a very detailed journal, so hopefully that will help

The main issue with testing is false positives. It's reasonable to get the test, eliminate everything that comes up, and see if you feel better. If so you challenge the foods one at a time. Problem is if you're reacting to a lot of stuff you may have so many ELISA reactions that the resulting diet is wildly impractical and/or doesn't help because you are sensitive to things other than the 96 that were tested.

Skin prick tests can only diagnose food allergies which produce skin reactions, like hives, eczema, etc. We don't put food under our skin when we eat, so allergies which produce other kinds of reactions are not reliably diagnosed with skin tests.

RAST tests look for IgE antibody mediate allergies, which cause immediate, often anaphylactic reactions. We hear about those kinds of allergies frequently, because they can be life threatening.

However most people have delayed reaction allergies (mediated by either IgA or IgG antibodies). Some 'experts' consider those kinds of delayed reactions 'intolerances', rather than allergies. However those reactions involve the immune system. So others consider those reactions allergies, unlike lactose intolerance, which doesn't involve the immune system. The ELISA test looks for all three kinds of reactions (IgE, IgG and more recently IgA antibody mediated). So ELISA can more often diagnose delayed reaction allergies, than RAST or skin prick tests.

Gluten, dairy, soy, egg, cane sugar, vanilla and nutmeg free. Enterolab diagnosed gluten/casein intolerant 7/04; soy intolerant 8/07. ELISA test diagnosed egg/cane sugar IgG allergies 8/06; vanilla/nutmeg 8/06. 2006-10 diagnosed by DNA Microbial stool tests and successfully treated: Klebsiella, Enterobacter Cloaecae, Cryptosporidia, Candida, C-diff, Achromobacter, H. Pylori and Dientamoeba Fragilis. 6/10 Heidelberg capsule test diagnosed hypochloridia. Vitamin D deficiency, hypothyroiditis, hypochloridia and low white blood cells caused vulnerability to infections. I now take Betaine HCl, probiotics, Vitamin D and T3 thyroid supplement to maintain immunity.

If you recognize that all these allergy/intolerance tests have a certain degree of unreliability, I did find that they were helpful for me.

My gluten responses are delayed by about three days. That makes it a little difficult to identify problems. I knew I was having problems with more than gluten. We have a gluten-free household and we donít eat out. I had identified raisins, dates, honey, agave and xylitol as problems but then was stumped. Last summer I did an IgG blood test for 96 food items and among a few other things came up with cane sugar as a sensitivity. Trial showed beet sugar (not included in the test) to also be a problem. There was moreóbut what? I went back to my very basic menuógrass-fed beef, brown rice, vegetables and dairy. Still a problem so I started going through all my supplements. When symptoms are delayed by three days, it takes a long time.

Soy? Corn? Fructose? Where to start? When I had done Enterolab testing a year and a half ago, I donít think they were offering any of the food testing they now have. Even though it is a bit expensive, I decided to do their 11 food fecal test and also the soy test add-on. Imagine my surprise with I found soy and corn to be OK but my problem foods were oats and rice. One day off of rice made a big difference. It cost me $450 for the test but it would have taken me years to suspect rice as a problem. That was one of my sonís basic foods (along with bananas and lamb) when on the celiac diet as a baby.

Thanks for the response Lori.
Were these all things that you talked to a food allergist with or general doctor?
An allergist is one doctor I haven't seen. Like I've said...at this point, I haven't really proven that food consumption is my problem but I have strong reason to think it is.
Thanks again

I heard from my ND that unreliable results from allergy blood tests often come from: (1) misinterpretation of results (assuming every reaction means an allergy, rather than considering the whole pattern of reactions, so that someone with many low reactions and a few moderate to high reactions should consider only the moderate to high reactions); and (2) lack of quality control standards within the lab processing the results (which can cause misreading of results or even overlooking valid results).

I suspect your 96 food IgG blood test was ELISA. I was also surprised by my results. One of my highest reaction allergies was cane sugar, which I never suspected. Unlike you, I'm fine with beet sugar, but react to cane. Also I took the herb and spice panel of ELISA and was diagnosed with vanilla and nutmeg allergies. Accidental consumption after I received those results corroborated (with painful gut symptoms) what the tests diagnosed.

When my frequent, loose bowel movements turned into diarrhea and I lost 15 pounds in two months, celiac was one of the first things I thought of. After two months of improvement on a gluten-free diet, I asked my doctor for celiac testing. I did not know you had to be eating gluten to get a positive test. Unfortunately, my doctor didnít know eitheróso, of course, my test was negative. He sent me to a GI. After telling him my experience and showing him my food diary, he simply told me to ďeat what you want and take Imodium.Ē So everything else has been on my ownótesting that I could find available, food diary, reading books, internetóbut of most importance, what I have learned from this forum. I really feel that anyone who has been on this forum for any length of time is more knowledgeable than my doctor.

But how/where did you get your blood testing and other testing done?
And I agree, the people here are very helpful.
