Possible False Negative Test?

Hi! I was tested for Celiac about a year ago, and got a negative result. Before that, I had been in and out of the doctor's office for a couple other different things. I had been having stomach pain for a while, and was tested for appendicitis. During the required blood tests, the doctor found that I was very, very anemic. Also, it turned out that the stomach pain was being caused by various ovarian cysts. I was put on iron supplements for the anemia and birth control pills to control the cysts. However, I was still having stomach pain, and my hemoglobin and ferratin levels weren't returning to normal. My doctor tested for celiac disease after about six months of this. The test came back negative.

Now, a year later, I am still on high-dosage iron pills and birth control. The doctor says that the anemia is from my heavy periods, but if that was the case, I would think that my lighter periods (due to the birth control) would help my anemia. I believe that the pill is helping the ovarian cyst pain, but I still have random stomach pains. I'm always tired, and I sometimes feel like I'm going to throw up. There are some days when I just can't eat. Another thing that makes me think celiac is a possibility is that five members of my family have autoimmune diseases. (Crohns, ITP, rheumatoid arthritis, autoimmune hepititis, psoratic arthritis.)

So, I'm basically asking if I should be retested. I have to get my blood drawn anyways thanks to the anemia, and with the relatively high false negative rate, I was wondering if it was even possible that I got a false-negative test result.

Sorry for such a huge post... it's been an interesting year and a half. :/ Thank you for reading!

Hi cassthedancer and welcome! :D

You have quite a few indicators of celiac disease (at least four, five with family history). I'd get retested, and if the results were negative, I'd give gluten-free a whirl.

Wish I had way back when...versus letting my diet snap me practically lifeless. (Dumb thing I did even when symptomatic because doctors didn't tell me what to do.)

Retesting can't hurt and absolutely try the diet once you're done with the testing. There are plenty of folks who get very sick from gluten and never have any sort of positive lab test or biopsy.

Thanks to both of you! :) I guess I just needed some reassurance before I asked the doc to retest.

I've been anemic off and on forever. The hematologist said it was either gyn or GI in nature... The gyn said it was heavy periods but that didn't explain my anemia when I was on bc before! The funny part is that when my iron went up with IV infusions, my periods got heavier and more regular! Anemic again, my periods stop almost totally. I really think my lousy periods are a result of malnutrition.

Now I'm going the GI route and have a biopsy in a month. I'm mad I didn't do this sooner. I had a ttg test that was negative 2 yrs ago, and I didn't question it or go gluten-free because my GP insisted ttg was "accurate enough." Sadly, this is the best doc I've ever had.

Anyhow, retesting can't hurt if you're in a position to do it, but I think regardless, it can't hurt to try gluten-free life you know? That's where I'm at, anyway.

      Welcome to the celiac.com community, @ThomasA55! Before I give my opinion on your question about whether or not you should undergo a gluten challenge, I would like to know how you react when you get a good dose of gluten? Are you largely asymptomatic or do you experience significant illness such as nausea and diarrhea? You mentioned intermittent joint pain before you began experimenting with a low gluten diet. Anything else?

      This is way past due for your post.  I have Celiac and have been recovering for more than a year.  Doing well.  Used Essential oil to day to fry some chicken.  Read the label all good.  Then ate some chicken.  Here comes the gluten reaction.  I haven't had a gluten reaction since year.  I am angry.   I have been so careful with this crap and don't wan't any set backs!!!!! Good luck to you with your post.   Celiac is HELL!

      Hey everyone. I'm a young adult who had very high iron in 2024. 64% saturation 160 ferritin. In 2025 I had far lower iron. 26% saturation and 130 ferritin. I know this is still in range but it seems to be a large drop. That combined with the fact that I developed some intermittent joint pain between the two years makes me wonder if I could be celiac. My dietary intake of iron was pretty steady (mostly in the form of red meat). I did carnivore (therby eliminating gluten) for a bit after the second test and felt improvements in my joints and digestion. I still consume gluten occasionally socially, for religious reasons, and through cross contamination/food sharing. For these reasons, I would need to know if I had it, because although my lifestyle is low gluten its not at the strict level it should be if it turned out I was celiac. I will get a gene test first and hope I don't have DQ2.5,DQ2.2, or DQ8, but if I had any combination of those do you guys think I need proper screening through a gluten challenge / blood test? Other context. From 2024-2025, my b12 stayed about the same in the mid 600s folate went up slightly, but I heard it takes longer for celiac to affect the absorption of these. ANA negative, CRP low, ESR low.  I don't know how much noise exists around the saturation and ferritin, but it caught my eye and Celiac seemed like a possibility. I'm under no illusion that it is probable that I have celiac, only that it may be worth screening given my overall profile.

      Sigh. I posted this yesterday based on the Safeway website. I went back again today to their website to double check. On the page where they are selling Vanilla Bean flavor, it has a distinct Certified Gluten Free label. Other flavors on the Safeway website didn't have the gluten-free statement. Today I went into the store. None of the flavors I looked at, including Vanilla Bean, have a Gluten Free statement. Is it safe? Who knows. The ingredients are either safe or nearly safe (some have "natural flavor"). There are warnings about "contains milk and soy" but not about wheat - this implies they are safe, but again, who knows. On the other hand, every flavor I checked of their Slow Churn line of ice creams has wheat as an ingredient. 100% not safe.

      Do keep in mind that many of the newly diagnosed have lactose intolerance.  This is because the villi lining the intestinal tract are damaged, and can no longer make the enzyme lactAse which breaks down the milk sugar lactOse.  When the villi grow back (six months to two years), they can again produce the enzyme lactAse, and lactose intolerance is resolved.  However, some people (both those with and without Celiac Disease) are genetically programmed to stop producing lactase as they age.   Do be aware that many processed foods, including ice cream, use Microbial Transglutaminase, a food additive commonly called "meat glue," used to enhance texture and flavor.  This microbial transglutaminase has the same immunogenicity as tissue transglutaminase which the body produces in response to gluten in people with Celiac Disease.  Tissue Transglutaminase (tTg IgA) is measured to diagnose Celiac Disease in blood tests.  Microbial Transglutaminase acts the same as Tissue Transglutaminase, causing increased intestinal permeability and inflammation.   New findings show that microbial transglutaminase may be able to trigger Celiac Disease and other autoimmune and neurodegenerative diseases.   Microbial Transglutaminase is not required to be listed on ingredients labels as it's considered a processing aid, not an ingredient in the U.S.  Microbial Transglutaminase has been GRAS for many years, but that GRAS standing is being questioned more and more as the immunogenicity of microbial transglutaminase is being discovered. Interesting Reading:  Microbial Transglutaminase Is a Very Frequently Used Food Additive and Is a Potential Inducer of Autoimmune/Neurodegenerative Diseases https://pmc.ncbi.nlm.nih.gov/articles/PMC8537092/
