Possible False Negative

I have been having stomach pains in my upper abdomen, feelings of fullness that sometimes lead to vomiting, distention, and headaches. I have been tested for celiac, lactose intolerance, gallbladder disease, etc... Everything has come back negative.

My question is whether anyone thinks I could have had a false negative test for celiac.

I recently had a genetics test done. It showed that I am three times more likely than average to have celiac. It also showed that I have a gene that is related to a significantly higher risk of having an Iga deficiency, which can sometimes cause a false negative. Also, I generally feel better when I am not eating wheat products.

Is this something I should tell my doctor? Could I have celiac disease even though my blood test was negative?

Thanks!

Yes yes Yes!

Do you have the lab results?

If they did not test you for IgA (total) and then tested you for the celiac antibodies that are also IgA, you could have a false negative if your IgA is deficient.

Definitely false negatives are common. You may also have a non-celiac form of gluten intolerance that causes similar symptoms but does NOT show up in blood work or biopsy...

Good luck! If they refuse to test you, you have nothing to lose by trying the gluten free diet and see if there is improvement.

I do not have the results. I actually called my doctor to get all of my medical records and they failed to send me the celiac test results. I am very curious to see what exactly they tested for and the results. My understanding is that you can be borderline and they may read your test as being negative, but you may actually have it.

I have been eating gluten free and it has definitely helped!

      Draft gluten-free ciders… can they be trusted ?

      By Rejoicephd · Posted

      @Scott Adams That's actually exactly what I ended up asking for— vodka tonic with Titos.  I saw on their website that Tito's is certified gluten-free (maybe many of the clear vodkas are, I don't know, I just happened to look up Tito's in advance). I should have actually specified the 'splash' though, because I think with the amount of tonic she put in there, it did still end up fairly sweet.  Anyway, I think I've almost got this drink order down!

      Be interesting to see the effects of dairy reintroduction with gluten. As well as milk protein sensitivity in and of itself the casein part particularly has been shown to mimic gluten in about 50% of celiacs. Keep us posted!

      She has been dairy free for six years, so she’d already been dairy free for two years at her last testing and was dairy free for the entire gluten challenge this year as well (that had positive results). However, now that we’re doing another biopsy in six weeks, we decided to do everything we can to try to “see” the effects, so we decided this past week to add back in dairy temporarily for breakfast (milk and cereal combo like you said).

      How Come Gluten Didnt Bother Me In Italy

      By Gigi2025 · Posted

      Hi Christiana, Many thanks for your response.  Interestingly, I too cannot eat wheat in France without feeling effects (much less than in the US, but won't indulge nonetheless).  I also understand children are screened for celiac in Italy prior to starting their education. Wise idea as it seems my grandson has the beginning symptoms (several celiacs in his dad's family), but parents continue to think he's just being difficult.  Argh.  There's a test I took that diagnosed gluten sensitivity in 2014 via Entero Labs, and am planning on having done again.  Truth be told, I'm hoping it's the bromine/additives/preservatives as I miss breads and pastas terribly when home here in the states!  Be well and here's to our guts healing ❤️

      Lol that’s so true! Hope you get clarity, it’s tough when there’s doubt. There’s so much known about celiac disease with all the scientific research that’s been done so far yet practically and clinically there’s also so much unknown, still. Out of curiosity what’s her dairy consumption like? Even compared to early years to now? Has that changed? Calcium is dependent in the mechanism of antigen presenting cells in the gut. High calcium foods with gluten grains can initiate inflammation greater.  This is why breakfast cereals and milk combo long term can be a ticking time bomb for genetically susceptible celiacs (not a scientific statement by any means but my current personal opinion based on reasoning at present). Milk and wheat are the top culprits for food sensitivity. Especially in childhood. There are also patient cases of antibodies normalising in celiac children who had milk protein intolerance/ delayed type allergy. Some asymptomatic. There were a couple of cases of suspected celiacs that turned out to have milk protein intolerance that normalised antibodies on a gluten containing diet. Then there were others that only normalised antibodies once gluten and milk was eliminated. Milk kept the antibodies positive. Celiac disease is complicated to say the least.
