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.

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 don

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

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 didn

      New (possible) celiac diagnosis

      By trents · Posted

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      New (possible) celiac diagnosis

      By Judy M · Posted

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.

      Gluten free beer ?

      By Scott Adams · Posted

      In this case the beer is excellent, but for those who are super sensitive it is likely better to go the full gluten-free beer route. Lakefront Brewery (another sponsor!) has good gluten-free beer made without any gluten ingredients.

      Welcome to the forum, @catsrlife! Celiac disease can be diagnosed without committing to a full-blown "gluten challenge" if you get a skin biopsy done during an active outbreak of dermatitis herpetiformis, assuming that is what is causing the rash. There is no other known cause for dermatitis herpetiformis so it is definitive for celiac disease. You would need to find a dermatologist who is familiar with doing the biopsy correctly, however. The samples need to be taken next to the pustules, not on them . . . a mistake many dermatologists make when biopsying for dermatitis herpetiformis.
