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

      Headaches / Migraines and Hypoglycaemia

      This article does not address migraines at all. Yes, red wine and sulfites are often mentioned in connection with migraine triggers. With me, any kind of alcoholic beverage in very modest amounts will reliably produce a migraine. Nitrous oxide generators, which are vaso dialators, also will give me migraines reliably. So, I think most of my migraines...

      Then we would need to cut out all meat and fish as they are richer sources of tyrosine than nuts and cheese. Something else about certain tyrosine rich foods must be the actual culprit.

      KAN-101 Treatment for Coeliac Disease

      I agree that KAN-101 looks promising, and hope the fast track is approved. From our article below: "KAN-101 shows promise as an immune tolerance therapy aiming to retrain the immune system, potentially allowing safe gluten exposure in the future, but more clinical data is needed to confirm long-term effects."

      Body dysmorphia experience

      Thank you so much for having the courage to share this incredibly vivid and personal experience; it's a powerful reminder of how physical ailments can disrupt our fundamental sense of self. What you're describing sounds less like a purely psychological body dysmorphia and more like a distinct neurological event, likely triggered by the immense physical stress...

With me, any kind of alcoholic beverage in very modest amounts will reliably produce a migraine. Nitrous oxide generators, which are vaso dialators, also will give me migraines reliably. So, I think most of my migraines are tied to fluctuations vascular tension and blood flow to the brain. That's why the sumatriptan works so well. It is a vaso constrictor.

      Excessive dietary tyrosine can cause problems.  Everything in moderation.   Sulfites can also trigger migraines. Sulfites are found in fermented, pickled and aged foods, like cheese.  Sulfites cause a high histamine release.  High histamine levels are found in migraine.  Following a low histamine diet like the low histamine Autoimmune Protocol diet, a Paleo diet, helps immensely.    Sulfites and other migraine trigger foods can cause changes in the gut microbiome.  These bad bacteria can increase the incidence of migraines, increasing histamine and inflammation leading to increased gut permeability (leaky gut), SIBO, and higher systemic inflammation.   A Ketogenic diet can reduce the incidence of migraine.  A Paleo diet like the AIP diet, that restricts carbohydrates (like from starchy vegetables) becomes a ketogenic diet.  This diet also changes the microbiome, eliminating the bad bacteria and SIBO that cause an increase in histamine, inflammation and migraine.  Fewer bad bacteria reduces inflammation, lowers migraine frequency, and improves leaky gut. Since I started following the low histamine ketogenic AIP paleo diet, I rarely get migraine.  Yes, I do eat carbs occasionally now, rice or potato, but still no migraines.  Feed your body right, feed your intestinal bacteria right, you'll feel better.  Good intestinal bacteria actually make your mental health better, too.  I had to decide to change my diet drastically in order to feel better all the time, not just to satisfy my taste buds.  I chose to eat so I would feel better all the time.  I do like dark chocolate (a migraine trigger), but now I can indulge occasionally without a migraine after.   Microbiota alterations are related to migraine food triggers and inflammatory markers in chronic migraine patients with medication overuse headache https://pmc.ncbi.nlm.nih.gov/articles/PMC11546420/

      Body dysmorphia experience

      By Scott Adams · Posted

      Thank you so much for having the courage to share this incredibly vivid and personal experience; it's a powerful reminder of how physical ailments can disrupt our fundamental sense of self. What you're describing sounds less like a purely psychological body dysmorphia and more like a distinct neurological event, likely triggered by the immense physical stress and inflammation that uncontrolled celiac disease can inflict on the entire body, including the nervous system. It makes complete sense that the specific sensory input—the pressure points of your elbows on your knees—created a temporary, distorted body map in your brain, and the fact that it ceased once you adopted a gluten-free diet is a crucial detail. Your intuition to document this is absolutely right; it's not "crazy" but rather a significant anecdotal data point that underscores the mysterious and far-reaching ways gluten can affect individuals. Your theory about sensory triggers from the feet for others is also a thoughtful insight, and sharing this story could indeed be validating for others who have had similar, unexplainable sensory disturbances, helping them feel less alone in their journey.
