Question About Celiac Panel

Does anyone know how long AFTER going gluten-free your tests will show up positive? I know that you have to be on gluten 1-3 months before testing to hope for the best from a test. I was about a month gluten-free before I had the bloodwork done. The PA ordered the test and when I asked her if I had to be eating gluten, she looked at me like I had two heads and said no, we just test for the antibody... WOW

So anyway, now I am going to a GI tomorrow for another problem, but I was going to mention this to him. Just wondering, I haven't read anywhere that states how quickly the antibodies disappear...

Anyone know?

it varies *GREATLY* from person to person. it entirely depends on how much damage you've had, how quickly you heal, and how long you've been gluten free, and those things are not entirely interdependent. after a month, you definitely run a risk of showing a false negative. I showed inconclusive after two weeks (but I don't think I had been gluten intolerant very long. (I think it had been triggered about nine months before I was tested), and I don't think I had much damage, and I heal fairly quickly.)

I agree----it can vary greatly, as tarnalberry noted.

The nutritionist at the Univ of MD Celiac Center has said that for some people, changes in the biopsy can be seen within one week of a gluten free diet. Some of the blood tests can correspond to the damage in the intestine.

You can also be in total end stage celiac and still show up negative on the blood tests. Waving both arms in the air vigorously here :D Do not base your need for the diet solely on blood or even endo. Judge by your response to the diet followed strictly. As mentioned the time for the antibodies to leave the body varies greatly. Are you getting any relief fromt the diet?

I have experienced tremendous results from the diet. My headaches are pretty much gone, and my fatigue is slowly going away. I can at least make it through the afternoon without napping now. :)

As for the appt with the GI:

When I told him that I did an elimination diet to determine if I was allergic to something, and found that it was wheat; whether an allergy or an intolerance, I don't know, nor at this point is it important. I was not going to undergo another month or so of feeling horrible just to find out. I wasn't in his office for that either. It was a follow up appt for a trip to the ED on account of my stomach feeling like it was on fire... which he really didn't talk about.

The ED Dr gave me pepcid, which constipated me... SO the GI's solution was to give me a laxative and another script, which I decided last night to not get filled. I just don't think that going on a laxative is a good idea. He didn't seem to care about the pepcid, so I am going to try it for a few days without.

However (and this is the kicker), he said: "What happened was this, when you went on your elimination diet and cut out a food group, you changed the motility of your bowels. You essentially did the Atkins diet, and changed everything. Now we have to get it regulated."

To which I replied... NO! I didn't do the Atkins diet, I made sure to get my carbs from alternative grains (Nutrition is what I want to do!) besides which I've already told you that several other family members have digestive problems, 3 of 4 of them with wheat/gluten.

Then he paid attention.

      Supplements for those Diagnosed with Celiac Disease

      Raising you vitamin D will increase absorption of calcium automatically without supplementation of calcium. A high PTH can be caused by low D causing poor calcium absorption; not insuffient calcium intake. With low D your body is not absorbing calcium from your food so it steals it from your bones.

      results from 13 day gluten challenge - does this mean I can't have celiac?

      @catnapt, Wheat germ has very little gluten in it. Gluten is the carbohydrate storage protein, what the flour is made from, the fluffy part. Just like with beans, there's the baby plant that will germinate ("germ"-inate) if sprouted, and the bean part is the carbohydrate storage protein. Wheat germ is the baby plant inside a kernel of wheat...

      Supplements for those Diagnosed with Celiac Disease

      Hello, @asaT, I'm curious to know whether you are taking other B vitamins like Thiamine B1 and Niacin B3. Malabsorption in Celiac disease affects all the water soluble B vitamins and Vitamin C. Thiamine and Niacin are required to produce energy for all the homocysteine lowering reactions provided by Folate, Cobalamine and Pyridoxine. Weight...

      Desperately need a vitamin D supplement. I've reacted to most brands I've tried.

      Hi Jane: You may want to try the D3 I now take. I have reactions to fillers and many additives. Sports Research, it is based in the USA and I have had no bad reactions with this brand. The D3 does have coconut oil but it is non GMO, it is Gluten free, Soy free, Soybean free and Safflower oil free. I have a cupboard full of supplements that did not agree...

      Raising you vitamin D will increase absorption of calcium automatically without supplementation of calcium.  A high PTH can be caused by low D causing poor calcium absorption; not insuffient calcium intake.  With low D your body is not absorbing calcium from your food so it steals it from your bones.  Heart has priority over bone. I've been taking 10,000 IU D3 a day since 2015.  My doctor says to continue. To fix my lactose intolerance, lots of lactobacillus from yogurts, and brine fermented pickles and saurkraut and olives.  We lose much of our ability to make lactase endogenosly with maturity but a healthy colony of lactobacillus in our gut excretes lactase in exchange for room and board. The milk protein in grass fed milk does not bother me. It tastes like the milk I grew up on.  If I drink commercial milk I get heartburn at night. Some experts estimate that 90% of us do not eat Adequite Intake of choline.  Beef and eggs are the principle source. Iodine deficiency is a growing concern.  I take 600 mcg a day of Liquid Iodine.  It and NAC have accelerated my healing all over.  Virtually blind in my right eye after starting antihypertensive medication and vision is slowly coming back.  I had to cut out starches because they drove my glucose up into the 200+ range.  I replaced them with Red Bull for the glucose intake with the vitamins, minerals and Taurine needed to process through the mitochodria Krebs Cycle to create ATP.  Went from A1c 13 down to 7.9.  Work in progress. Also take B1,B2,B3,B5,B6. Liquid Iodine, Phosphatidyl Choline, Q10, Selenium, D and DHEA.     Choline supplemented as phosphatidylcholine decreases fasting and postmethionine-loading plasma homocysteine concentrations in healthy men +

Luckily you still have time to do a proper gluten challenge (10 grams of gluten per day for a minimum of two weeks) before your next appointment when you can be retested.

      Hello, @asaT, I'm curious to know whether you are taking other B vitamins like Thiamine B1 and Niacin B3.  Malabsorption in Celiac disease affects all the water soluble B vitamins and Vitamin C.  Thiamine and Niacin are required to produce energy for all the homocysteine lowering reactions provided by Folate, Cobalamine and Pyridoxine.   Weight gain with a voracious appetite is something I experienced while malnourished.  It's symptomatic of Thiamine B1 deficiency.   Conversely, some people with thiamine deficiency lose their appetite altogether, and suffer from anorexia.  At different periods on my lifelong journey, I suffered this, too.   When the body doesn't have sufficient thiamine to turn food, especially carbohydrates, into energy (for growth and repair), the body rations what little thiamine it has available, and turns the carbs into fat, and stores it mostly in the abdomen.  Consuming a high carbohydrate diet requires additional thiamine to process the carbs into energy.  Simple carbohydrates (sugar, white rice, etc.) don't contain thiamine, so the body easily depletes its stores of Thiamine processing the carbs into fat.  The digestive system communicates with the brain to keep eating in order to consume more thiamine and other nutrients it's not absorbing.   One can have a subclinical thiamine insufficiency for years.  A twenty percent increase in dietary thiamine causes an eighty percent increase in brain function, so the symptoms can wax and wane mysteriously.  Symptoms of Thiamine insufficiency include stunted growth, chronic fatigue, and Gastrointestinal Beriberi (diarrhea, abdominal pain), heart attack, Alzheimer's, stroke, and cancer.   Thiamine improves bone turnover.  Thiamine insufficiency can also affect the thyroid.  The thyroid is important in bone metabolism.  The thyroid also influences hormones, like estrogen and progesterone, and menopause.  Vitamin D, at optimal levels, can act as a hormone and can influence the thyroid, as well as being important to bone health, and regulating the immune system.  Vitamin A is important to bone health, too, and is necessary for intestinal health, as well.   I don't do dairy because I react to Casein, the protein in dairy that resembles gluten and causes a reaction the same as if I'd been exposed to gluten, including high tTg IgA.  I found adding mineral water containing calcium and other minerals helpful in increasing my calcium intake.   Malabsorption of Celiac affects all the vitamins and minerals.  I do hope you'll talk to your doctor and dietician about supplementing all eight B vitamins and the four fat soluble vitamins because they all work together interconnectedly.

The D3 does have coconut oil but it is non GMO, it is Gluten free, Soy free, Soybean free and Safflower oil free.  I have a cupboard full of supplements that did not agree with me -  I just keep trying and have finally settled on Sports Research. I take NAKA Women's Multi full spectrum, and have not felt sick after taking 2 capsules per day -  it is a Canadian company. I buy both from Amazon. I wish you well in your searching, I know how discouraging it all is. Florence.

      highly unlikely  NOTHING and I mean NOTHING else has ever caused me these kinds of symptoms I have no problem with dates, they are a large part of my diet In fact, I eat a very high fiber, very high vegetable and bean diet and have for many years now. It's considered a whole foods plant based or plant forward diet (I do now eat some lean ground turkey but not much) I was off dairy for years but recently had to add back plain yogurt to meet calcium needs that I am not allowed to get from supplements (I have not had any problem with the yogurt)   I eat almost no processed foods. I don't eat out. almost everything I eat, I cook myself I am going to keep a food diary but to be honest, I already know that it's wheat products and also barley that are the problem, which is why I gradually stopped eating and buying them. When I was eating them, like back in early 2024, when I was in the middle of moving and ate out (always had bread or toast or rolls or a sub or pizza) I felt terrible but at that time was so busy and exhausted that I never stopped to think it was the food. Once I was in my new place, I continued to have bread from time to time and had such horrible joint pain that I was preparing for 2 total knee replacements as well as one hip! The surgery could not go forward as I was (and still am) actively losing calcium from my bones. That problem has yet to be properly diagnosed and treated   anyway over time I realized that I felt better when I stopped eating bread. Back at least 3 yrs ago I noticed that regular pasta made me sick so I switched to brown rice pasta and even though it costs a lot more, I really like it.   so gradually I just stopped buying and eating foods with gluten. I stopped getting raisin bran when I was constipated because it made me bloated and it didn't help the constipation any more (used to be a sure bet that it would in the past)   I made cookies and brownies using beans and rolled oats and dates and tahini and I LOVE them and have zero issues eating those I eat 1 or more cans of beans per day easily can eat a pound of broccoli - no problem! Brussels sprouts the same thing.   so yeh it's bread and related foods that are clearly the problem  there is zero doubt in my mind
