Test In 2 Weeks, But I've Been gluten-free...

I've cut out gluten for the last few months. A couple of times I reintroduced it as a test, and since there was definitely noticeable digestive reactions (diarrhea, cramps, bloating, etc.) I want to get actually tested for celiac disease. I just got an appointment to go into my student health clinic in two weeks - since I haven't been eating gluten, is that too soon? The test itself may not happen that day, so I could postpone it. If I eat wheat-y, gluten-tastic food between now and then, will that be enough for my body to be producing "high levels of antibodies" or whatever it is that the test detects?

Should I only eat a little bit of gluten in that time? Should I eat more?

You really need to get back on a full gluten diet for at least 3 months before testing. The tests are for antibodies and if you haven't been eating gluten you are not producing enough antibodies for the test to have any chance of being positive. Even on a full gluten diet the tests may be a false negative. If your body rebels strongly to gluten that is pretty diagnostic in itself. One other option you have is Enterolab, they do not diagnose celiac but they can look for the antibodies in the stool, your body does not produce antibodies to something it wants in your body.

You need to be eating a normal gluten containing diet for the tests to be accurate. If you have been gluten free (generally), the tests decrease in accuracy.

You've been gluten free for a couple months, there is no reason to expect blood testing to be accurate.

As noted, you need to be eating plenty of gluten (~3 slices of bread a day, or the equivalent) for quite a while (3 months).

I'm currently in the same situation. I've been gluten-free for 7 years, and I'm having blood testing and an endoscopy done this Friday. I've been ordered by my doctor to eat gluten for the next three days. I had a bagel sandwich and chicken noodle soup. This resulted in severe bloating, constipation, vertigo, and severe fatigue. So I would say 2 weeks is enough if you eat a little bit of gluten everyday.

Clearly your gluten challenge is positive however you can fully expect to have negative blood work and endoscopy. You were fully healed and you must redamage yourself enough to destroy your villi for an endoscopic exam. Three days is definately not enough of a challenge for either positive blood work or biopsy if you have been gluten free for 7 years. Your doctor is not well educated about celiac, sorry to say.

I figured he wasn't very educated on Celiacs from when I met with him, but this is my only option in trying to prove I have it to live off-campus at my college.

If that is what you need to do I would ask the doctor to schedule the test for August and get back on a full gluten diet until then. If you have been gluten-free for years did you already get diagnosed as a child? Or did you have problems as a child that lead the doctor to advise the diet? If so perhaps your ped already diagnosed you, I would give them a call to find out.

      4.5 years into diagnosis, eating gluten-free and still struggling: would love support, tips, & stories

      Hi and thank you very much for your detailed response! I am so glad that the protocol worked so well for you and helped you to get your health back on track. I've heard of it helping other people too. One question I have is how did you maintain your weight on this diet? I really rely on nuts and rice to keep me at a steady weight because I tend to lose weight quickly and am having a hard time envisioning how to make it work, especially when not being able to eat things like nuts and avocados. In case you have any input, woud be great to hear it! Friendly greetings.

      Is this celiac?

      I was not taking any medications previous to this. I was a healthy 49 yo with some mild stomach discomfort. I noticed the onset of tinnitus earlier this year and I had Covid at the end of June. My first ‘flare-up’ with these symptoms was in August and I was eating gluten like normal. I had another flare-up in September and then got an upper endo at the end of September that showed possible celiac. My blood test came a week later. While I didn’t stop eating gluten before I had the blood test, I had cut back on food and gluten both. I had a flare-up with this symptoms after one week of gluten free but wasn’t being crazy careful. Then I had another flare-up this week. I think it might have been caused by Trader Joe’s baked tofu which I didn’t realize had wheat. But I don’t know if these flare-ups are caused by gluten or if there’s something else going on. I am food journaling and tracking all symptoms. I have lost 7 pounds in the last 10 days.

      Welcome to the forum, @Hmart! There are other medical conditions besides celiac disease that can cause villous atrophy as well as some medications and for some people, the dairy protein casein. So, your question is a valid one. Especially in view of the fact that your antibody testing was negative, though there are also some seronegative celiacs. So, do you get reactions every time you consume gluten? If you were to purposely consume a slice of bread would you be certain to develop the symptoms you describe?

      Does anyone here also have Afib

      I only went on the multi vitamin AFTER a couple of year of high dose, targeted supplementation resolved most of my deficiencies.  I was on quite a cocktail of vitamins that was changed every 6 months as my deficiencies resolved.  Those that were determined to be genetic are still addressed with specific doses of those vitamins, minerals and amino acids. I have an update on my husband and his A Fib.  He ended up in the hospital in August 2025 when his A Fib would not convert.  He took the maximum dose of Flecainide allowed within a 24 hour period.  It was a nightmare experience!  They took him into the ER immediately.  They put in a line, drew blood, did an EKG and chest Xray all within minutes.  Never saw another human for 6 hours.  Never got any results, but obviously we could see he was still in A fib by watching the monitor.  They have the family sign up for text alerts at the ER desk.  So glad I did.  That is the only way we found out that he was being admitted.  About an hour after that text someone came to take him to his room on an observation floor.  We were there two hours before we saw another human being and believe it or not that was by zoom on the TV in the room.  It was admissions wanting to know his vaccine status and confirming his insurance, which we provided at the ER desk.  They said someone would be in and finally a nurse arrived.  He was told a hospitalist was in charge of his case.  Finally the NP for the hospitalist showed up and my husband literally blew his stack.  He got so angry and yelled at this poor woman, but it was exactly what he needed to convert himself to sinus rhythm while she was there.  They got an EKG machine and confirmed it.  She told him that they wanted to keep him overnight and would do an echo in the morning and they were concerned about a wound on his leg and wanted to do a doppler to make sure he did not have a DVT.  He agreed.  The echo showed everything fine, just as it was at his annual check up in June and there was no DVT.  A cardiologist finally showed up to discharge him and after reviewing his history said the A Fib was due to the Amoxicillan prescribed for his leg wound.  It both triggers A Fib and prevents the Flecainide from working.  His conversion coincided with the last dose of antibiotic getting out of his system.  So, make sure your PCP understands what antibiotics you can or cannot take if susceptible to A Fib.  This cardiologist (not his regular) wanted him on Metoprolol 25 mg and Pradaxa.  My husband told him that his cardiologist axed the idea of a beta blocker because his heart rate is already low.  Sure enough, it dropped to 42 on the Metoprolol and my husband felt horrible.  The pradaxa gave him a full body rash!  He went back to his cardiologist for follow up and his BP was fine and heart rate in the mid 50's.  He also axed the Pradaxa since my husband has low platelets, bruises easily and gets bloody noses just from Fish Oil  He suggested he take Black Cumin Seed Oil for inflammation.  He discovered that by taking the Black Seed oil, he can eat carbs and not go into A Fib, since it does such a good job of reducing inflammation.   Oh and I forgot to say the hospital bill was over $26,000.  Houston Methodist!
