Positive biopsy, carry gene variant but negative blood tests

Hello, i need some input. Two years ago I had an upper endoscopy with 6 biopsies showing some interepithelial lymphocytes and shortened villi so I was sent for blood work which came back negative but I had been on a gluten feee diet for 2-3 months prior to bloodwork.  What are the chances I had a false negative with the blood tests?  I’ve now been on a gluten free diet for 3 days and the change in my intestinal issues is remarkable.  Painful joints feel slightly better too. What should I do?  Oh, I also carry a gene which increases the likelihood of celiac.  Should I go back to eating gluten and ask for the blood tests to be repealed ???

thanks; Sarah

If you were gluten-free for months before the blood work, it should be negative.  It is meaningless as a test for Celaic at that point.  IF you have been eating gluten for the last 2 years, keep eating it and get a new blood test.

If you are going to get retested, ask for the complete celiac panel (EMA, TTG and DGP — both IgA and IgG versions.  Why?  I am one of the oddballs who has never tested positive (even in follow-up) on the popular and most commonly ordered TTG.  

If my GI had not ordered the complete panel, my diagnosis would not have been made.  I had a positive on the DGP IgA only.  My biopsies revealed a Marsh Stage IIIB.

Thanks,  Cycling Lady!  I’m going Thursday so that is helpful to know.

      I'm not saying this is what you have, but your description reminds me of Morgellons, which are not very well understood. Here is a review from a reputable source.

      Celiac flare years after diagnosis

      Hi Trent, no dairy. Other than good quality butter. I have been lactose free for years. No corn, sugar, even seasonings and spices. I don't eat out. I cook my own food.

      @nancydrewandtheceliacclue, are you consuming dairy? Not sure if dairy is part of the carnivore diet.

      Celiac flare years after diagnosis

      Hello Russ! Thank you so much for your reply. I have not had an antibody test done, ever, relating to gluten. Last year I had an allergy test done via blood draw (as my insurance wouldn't cover the skin test) but this was for pollen and grasses, not food. Even on the blood test I had extremely high levels of reactions to each allergen. Could this seasonal...

      Celiac flare years after diagnosis

      The sensitivity of people with coeliac disease varies greatly between individuals. The generally accepted as safe limit for most people is 10 milligrams per day. This equates to a piece of bread the size of a small pea. Some people report that they are more sensitive than this, but others can very occasionally eat a normal gluten containing meal without reacting...

      Hello Russ! Thank you so much for your reply.  I have not had an antibody test done, ever, relating to gluten. Last year I had an allergy test done via blood draw (as my insurance wouldn't cover the skin test) but this was for pollen and grasses, not food. Even on the blood test I had extremely high levels of reactions to each allergen. Could this seasonal allergy inflammation be contributing to my celiac inflammation? I am so careful, there is no way I could ingest gluten. For example, couple of months ago I tried a cough drop that says it was gluten free. I checked ingredients, it seemed fine. But just taking one of those caused me to have nausea, vomiting, and the same extreme abdominal pain. Have you ever heard of anyone else having symptoms like mine after being diagnosed celiac and strictly gluten free? The last episode I had like this was yesterday, after I ate a certified gluten-free coconut macaroon with a little chocolate on it. I have eaten coconut and chocolate before with no issue,  so I didn't see how I could all of a sudden have such a strong response.

      The sensitivity of people with coeliac disease varies greatly between individuals. The generally accepted as safe limit for most people is 10 milligrams per day. This equates to a piece of bread the size of a small pea. Some people report that they are more sensitive than this, but others can very occasionally eat a normal gluten containing meal without reacting. I don't think that touching or throwing bread around would lead to you ingesting enough to cause a reaction. There are case reports of farmers with coeliac disease reacting to the dust from gluten-containing animal feed but they were inhaling large amounts of dust over a long period of time in barns. Perhaps you episodes are caused by a reaction to something other than gluten? Have you had your antibody levels checked to see whether you are still being exposed to gluten?
