Testing Questions....

I've been gluten free now for about 2 years. I had first asked my allergist about gluten intolerance/celiac and he said the best test was to eliminate it and see if I felt better. I did eliminate it and fairly quickly felt better than I had my whole life.

Then a new Celiac clinic opened up. And they were offereing Celiac screenings. So I contacted the nurse in charge, told her i wanted to be screened but that I was already eating gluten-free. She said to eat gluten the 2 weeks leading up to the test. I did that (and felt terrible) and was tested. They did 2 blood tests (I think it was Total IgA and Trans IgA...I have them at home) but the results were within the normal range. Since they were normal, the center didn't pursue any further testing.

Regardless of the results, I continued my gluten-free diet b/c I felt so much better off it. But to this day, I wonder if those results were right. Was 2 weeks enough to be eating gluten for? What I read now suggests that you should be eating gluten for 6 weeks for it to show up on a blood test....

I won't be going back to eating gluten to get tested again. But now I am thinking that I might get the gene test done. If I have the gene, then I know that there's a possibility of celiac vs a gluten intolerance. Plus I know that I may have passed it to my daughters.

I don't know why but I just feel like I need to know....like I feel like a hypochondriac if I don't have some kind of "answer".... stupid I know....

Any opinions/advice? Thanks!

Well I'm sort of in the same boat. I had been gluten free for 3 months (not nearly as long as you!), then I saw a GI doctor who wanted to run the bloodwork. [i'm hoping to get a diagnosis so that my kids, who have been gluten free since birth except for a few 2-3 day trials that yielded horrible results, can be diagnosed without having to ever go through the testing. No way would I have them eat gluten for weeks and weeks!]

Anyway, I don't have my results yet. They ran the Prometheus Celiac Plus test, which does the serum and the genes. The doctor and nurse both assured me that 2 weeks on gluten, as long as I "hit it hard", should be sufficient. I felt like garbage the whole time, but I really have my doubts whether it was long enough. We'll see I guess...

I don't think 2 weeks is long enough. I thought the standard gluten challenge was 3 months.

I don't know what to advise regarding how to proceed. The thought of eating gluten on purpose even for a week sounds awful to me. However, there are advantages to a definitive diagnosis. If it were me though, I don't think I'd eat the gluten.

I thought the bloodwork was independent of whether or not a person was eating gluten??? (My doctor thought so.) I was negative on my IGA & IGG tests (as below), but my blood was drawn after I'd stopped eating gluten. I'd been off for 6 weeks at that point.

I'm feeling miserable today after eating some oats yesterday, in Udi's gluten-free granola. I know not everybody with gluten intolerance has issues with oats, but (at least at this point) oh, I do! I think that's a better test than these labs.

The problem is that I'm still suffering from neuropathy, joint pain, fatigue, and, probably now, depression. Could this really be from gluten if I've been off it for 2 months? I know it's possible - statistical even - but I still find myself wondering ... it's hard not to have a definite diagnosis sometimes.

The blood tests can only tell you if you have a gluten problem, not if you don't. Your allergist was correct in the best form of "testing".

You need to be eating the equivelant of about 2 to 3 slices of bread for a good 2 to 3 MONTHS for the tests to show positive and even then you still may show negative. That is why for some people it can take up to 10 years or longer to get a diagnosis.

      Welcome to the celiac.com community, @Atl222! Yes, your increased lymphocytes could be in response to oats or it could possibly be cross contamination from gluten that is getting into your diet from some unexpected source but not enough to damage the villi. And I'm certain that increased lymphocytes can be caused by other things besides celiac disease or gluten/oats exposure. See attachment. But you might try eliminating oats to start with and possibly dairy for a few months and then seek another endoscopy/biopsy to see if there was a reduction in lymphocyte counts.

      This is a solid, well-reasoned approach. You’re right that “koji” by itself doesn’t indicate gluten status, and the risk really does come down to which grain is used to culture it. The fact that you directly contacted Eden Foods and received a clear statement that their koji is made from rice only, with no wheat or barley, is meaningful due diligence—especially since Eden has a long-standing reputation for transparency. While the lack of gluten labeling can understandably give pause, manufacturer confirmation like this is often what people rely on for traditionally fermented products. As always, trusting your body after trying it is reasonable, but based on the information you gathered, your conclusion makes sense.

      Seven months can still be early in celiac healing, especially if you were mostly asymptomatic to begin with—symptoms like low iron, vitamin D deficiency, nail changes, and hair issues often take much longer to improve because the gut needs time to recover before absorption normalizes. A tTG-IgA of 69 is not “low” in terms of immune activity, and it can take 12–24 months (sometimes longer) for antibodies and the intestinal lining to fully heal, particularly in teens and young adults. Eating gluten again to “test” things isn’t recommended and won’t give you clear answers—it’s far more likely to cause harm than clarity. Weight not changing is also very common in celiac and doesn’t rule anything out. Please know that your frustration and sadness matter; this adjustment is hard, and feeling stuck can really affect mental health. You deserve support, and if you can, reaching out to a GI dietitian or mental health professional familiar with chronic illness could really help you through this phase. This study indicates that a majority of celiacs don't recover until 5 years after diagnosis and starting a gluten-free diet: Mucosal recovery and mortality in adults with celiac disease after treatment with a gluten-free diet However, it's also possible that what the study really shows is the difficulty in maintaining a 100% gluten-free diet. I suspect that if you looked closely at the diets of those who did not recover within 2 years might be that their diets were not 100% gluten-free. Perhaps they ate out more often, or didn't understand all of the hidden ingredients where gluten can hide. Either way, it shows how difficult recovery from celiac disease can be for most people. According to this study: This article explores other causes of flattened villi:

      Gluten testing is normally reported in ppm (parts per million), which is equivalent to mg/kg, not micrograms by itself. A result of <0.025 mcg only becomes meaningful if you know the sample size tested (for example, mcg per gram or per kg). If that value represents <0.025 mcg per gram, that would equal <25 ppm, which is above the gluten-free threshold; if it’s <0.025 mcg per kilogram, it would be extremely low and well within GF limits. Without the denominator, the result is incomplete. It’s reasonable to follow up with the company and ask them to confirm the result in ppm using a validated method (like ELISA R5)—that’s the standard used to assess gluten safety.

      Medication sensitivity is very real for many people with celiac and other autoimmune conditions, and it’s frustrating when that’s brushed off. Even when a medication is technically gluten-free, fillers, dose changes, or how your nervous system reacts—especially with things like gabapentin—can cause paradoxical effects like feeling wired but exhausted. The fact that it helped bloating suggests it may be affecting gut–nerve signaling, which makes sense in the context of SIBO, but that doesn’t mean the side effects should be ignored. You’re carrying a heavy load right now with ongoing skin, eye, and neurological uncertainty, and living in that kind of limbo is exhausting on its own. It’s understandable to feel overwhelmed and discouraged when systems and providers don’t meet you where you are—your experience is valid, and continuing to advocate for yourself, even when it’s hard, really does matter. You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/
