Well, LEAP made the "dubious" list at Quackwatch.

http://www.quackwatch.org/01QuackeryRelatedTopics/Tests/allergytests.html

Another abstract with a similar conclusion. The author notes that information on mediator release testing is only found on consumer sites.

http://www.ncbi.nlm.nih.gov/pubmed/20413700

There are a lot of scams right now with diagnostic tests, to the point that FDA is looking hard at companies like this. The other big scam allergy test is IgG4.

:) Thanks, I was aware of the paper on PubMed. Their philosophy seems to be different than mainstream medicine, but I wonder if part of the poor review is because their MRT test is proprietary. I don't know how their lab test is performed. Maybe useful to hear from folks who may have used it to their benefit, or even otherwise. LEAP claims to have helped thousands of patients successfully. Dr. Scot Lewey (who wrote pretty informative articles on celiac disease and celiac disease testing available here on celiac.com) seems to recommend it for his patients. However, there doesn't seem to be much consumer input available. Interesting.

I'm so suspicious of testing services that refuse to establish (or at least provide) sensitivity and specificity measures for their tests.

You do realize allergists say the gold standard for food allergies is elimination, right? None of these tests "diagnose" food allergies or sensitivities. They can only guide what foods might be problematic if you're not willing to do lamb/rice/pears.

I personally think MRT, IgG4, Enterolab, and other consumer "diagnostic" services are creative ways to separate consumers from their $$ because Western medicine has people confused and overly attached to diagnostic test results.

Lol. I don't disagree with you regarding LEAP. I just looked up their patents, interesting. Not "state of the art" as they advertise. I'm just surprised there has been so little commentary about it, controversial as it is.

A word of caution ; I spent hours researching The owner of the website QUACKWATCH ; Do it on Google and you will find that he is a physician whom license is revoked and tied big-time to large pharmaceutical industry with a lot of suspicion about his income and whom supporting his website since he is out of business . His business is to discredit everything that gives answer to disease other than mainstream medicine that is hooked on giving lifetime drugs. Do not take my word for it checj it out yourselves. Signet MRT follows strict testing procedures and is used by Functional Medicine , Anti-Aging medicine all over the US and abroad ( ask someone who used it ) ; also used by metabolic typing . Do your homework . research and get well informed. A lot of websites are out-there to discredit money making drug companies and their allied health care providers. I do not do forums a lot but happened to see this part . Good luck .

Yeah, that quackwatch guy, Stephen Barrett, is no more reliable as a source of information than Glenn Beck. In one case that Quackwatch and the "National Council Against Health Fraud" tried to file against an alternative health company, the judge found National Council Against Health Fraud to be "biased and unworthy of credibility".

I haven't tried the LEAP test with any patients, but have used a combined IgE/IgG4 with a lot of people and it usually helps find things that people feel better when they don't eat, so the idea that it is necessarily "a scam" isn't supported by my experience. However, it is not diagnostic for celiac disease.

In my experience, no test is 100%. An elimination diet with careful re-challenging after 2w off all common allergens is the best bet for finding food sensitivities. The blood tests give a short-cut so people can do a smaller challenge.

Interesting. Your experience directly contradicts this peer-reviewed evaluation of IgG4.

http://www.ncbi.nlm.nih.gov/pubmed/18489614

"In conclusion, food-specific IgG4 does not indicate (imminent) food allergy or intolerance, but rather a physiological response of the immune system after exposition to food components. Therefore, testing of IgG4 to foods is considered as irrelevant for the laboratory work-up of food allergy or intolerance and should not be performed in case of food-related complaints."

As for Quackwatch, have you actually read the website? It's common sense stuff, largely based on peer-reviewed research and not all written by Barrett. Try this classic one on homeopathy. It's a wonderful read. http://www.quackwatch.org/01QuackeryRelatedTopics/homeo.html

    • Did your doctor check for SIBO, H. pylori, ulcers, etc. when he was obtaining biopsies to check for celiac disease?  
    • Oh, and as I mentioned in my own post on pain, xanax. I swear. I tried it just to deal with the occasional panic I had at weird scary symptoms and clueless doctors. I am not a fan of long term use. But I recently found that .25 mg seems to aid with the neuropathic pain. It does not go away, but it helps. 
    • It does sound like a Glutening and you are just a few months into the diet.  It might help if you read our Newbie 101 thread under the "Coping" section.   Here is some information about rice milk: https://www.verywell.com/is-rice-dream-gluten-free-562354 Many, many celiacs are often lactose intolerant temorarily or permanently if you are naturally genetically inclined.  When I am glutened, I lose the ability to digest lactose for a while.   Salad?  Great but it can be rough on a sore gut!  Think soups, stews, easy-to-digest foods that you prepare yourself until you feel better.  Did your folks give you salad after a bout of flu?  Or did you stick with jello and broth?  I am intolerant still after three years to garlic and onions (the lactose resolved, thankfully).  You have a leaky gut (Google zonulin and Dr. Fasano who is a leading celiac researcher to verify that this is true) and that means you can become intolerant to anything (hopefully, just temporarily).   If you are 100% sure that you have had no access to gluten....did you eat out lately?.....then see your doctor.  Remember, celiac disease symptoms can change.  And here is the biggie.....it can take weeks, months or years to heal from celiac disease.  Two months in is nothing, really.  Why?  It takes time to figure out the diet and time for antibodies to come down.  celiac disease is an autoimmune disorder triggerEd by gluten.  once triggered it can go on and on damaging your gut especially with repeated glutenings (accidental or through cross contamination). I hope you feel better soon!  
    • I concur! I literally feel your pain as well. Like, at the moment, lol. Did you have an endo to see inflammation or damage? I am close to begging my GI for carafate or something to coat and protect. How about testing your antibodies to see if they are still rising? I read somewhere here rice milk may not be a good option.  Folks here have also suggested to me to stick with whole foods. Limit processed. Especially stuff that is not certified gluten-free, like chex. I think small amounts of gluten are in processed foids and can add up. I too reacted to lettuce the other day like I was ingesting glass. My sibling  had a food sensitivity panel done and it came back positive for a few things he had been eating a lot of. He can now eat them, but had to cut them out of his diet. Lettuce is probably on mine.  I have been drinking carrot and pomegranate juice,  dandelion root tea with hiney, aloe water, lots of squash, fish. Mild, no garlic, no onions or hot sauce. No coffee. It sucks.  Inflammation can tick off other organs, you mention a "Pain below". Not exactly sure which side, but certainly call your doc Monday. Sooner if the pain increases.
    • You should see a GI specialist before you go gluten free.  They should do a upper endoscopy to check for celiac damage.  Colonoscopy won't show anything related to celiac.  Also no you should not feel worse on gluten free, you should feel better.
