I have a quick question about allergies and intolerances.
We did the Nutriscan test for food sensitivities. What I’m wondering is, if my dog showed a negative reaction/no sensitivity (both lgA and lgM) to a particular protein, could he still have an allergy to that protein? Or does the negative reaction basically rule out an allergy as well?
Thank you for all your help!
Dr. Steve's Advice - the test looks for antibodies to particular proteins. If they are lacking, it means that a reaction to that food is less likely.
That being said, dogs can have sensitivities seemingly in response to foods, without having antibodies against them. The most common example of this (I believe) is a leaky gut situation, where a food may just change the mix of bacteria in the gut, by feeding one species more than another. If that species was more pathogenic, it can create a leaky gut. The immune system on the other side of the gut wall responds, not necessarily by targeting the food that was eaten, but instead it targets the pathogenic gut bug. It panics and primes the entire system to be ready to respond in anticipation of a full scale breach of the intestinal tract (which won't happen, but it doesn't know that). It's the wholesale priming of the immune system that then revs up any inflammation already in progress, such as what might have been a low-grade yeast or bacterial skin infection becomes highly noticeable.
Along comes the vet, and they do a food allergy test. Finding no antibodies, they assure the owner that food is not an issue, even though the owner may have been wondering because they saw a ramping up in inflammation when they changed to a new food. Instead, the vet cultures a skin swab or does some cytology, finds the yeast overgrowth, and diagnoses it as a yeast infection, or a Staph infection or allergy. In this scenario, though, the problem would not resolve in response to antimicrobials or would come back quickly when they were discontinued, leaving the owner frustrated. Meanwhile, the antimicrobials potentially unbalance the microbiome even more.
This is likely an extremely common scenario and is why I harangue people to change the diet to one that uses real food, and then add in a Lactobacillus probiotic. This is why people are finding Cessorex works so well and so often - because it likewise targets the microbiome and then fans out from there. Cessorex doesn't kill the yeast or bacteria on the skin, but they are actually red herrings. Instead, it just fixes the original problem.
Now sometimes, it is a yeast or bacterial infection, and that's why I counsel people to add in Lift the Qi or Galvanex from Gold Standard Herbs next. Lift the Qi helps with the original microbiome issue AND targets the skin infection.
Hope that all makes sense. It's probably a much longer answer than you wanted!
