Prep For Blood Testing

6 posts in this topic

Hi everyone,

I have already written in about my son, and now it's for my husband that I have questions (questions about me will undoubtedly come soon!)

My husband is going to get himself tested for celiac because after we all went gluten-free due to our son's need, he, my husband, was amazed to find how much better he felt after a week or so. His chronic and sometimes severe fatigue disappeared.

He was gluten free for 5 weeks in total. Now he has gone back to consuming it in order to have the blood work done and it has been 3 weeks so far.

My question is this: how long is long enough to be back on gluten for valid test results? I have read various things and at the least it is clear that there are individual differences, so this is not an exact science I know. I have heard 4-6 weeks mentioned, but it is not clear how long people have been gluten-free prior to that, to make those number of weeks necessary to be back on gluten, if you see what I mean. Since he was only gluten-free for 5 weeks, perhaps it is not necessary to draw the ordeal out? The bottom line is, although he hates being back on the stuff he is also concerned that the test results be as accurate as possible.

ANy insight would be highly appreciated. Thanks,

Kaylee

I have the same question. I have been totally gluten free for about a month, and sporadically gluten free since the beginning of the year. I am now dreading the weeks that I will need to eat gluten. Worse yet, if I don't eat enough, they could misdiagnose me as non-celiac.

I have been told that you must eat wheat from 2 weeks to 4 months. However, I have also been told that 2 weeks is not enough and could give false negatives. I had planned to go 5 weeks, but would welcome input from others.

I don't know if I can take it. I get severe IBS, can't do my work and have even had heart palpitaitons and shortness of breath. Some threads have indicated that the symptoms will be worse if you have been off gluten for a while and go back on. This is not going to be fun.

Any suggestions? Jala.

After 5 days of eating wheat - so far so good. I am enjoying all the wheat items I had been avoiding for so long - pizza, bagels, oriental noodles, petit fors and french rolls (I'm doing pancakes, chips & dips and chicken fried steak w/ cream gravy this weekend). I figure if this is a last hurrah I'm going to do it big, plus this will help to assure my tests get some additional reinforcement.

All these forbidden foods were fun at first, but I was already constipated after only 2 days (but no severe pain or diarrhea yet). I have also inflated like a balloon and have gained a lot of weight. I am hoping to stay on wheat for 5 weeks only. For those of you avoiding wheat and longing for it, let me tell you. It is not all I hoped for. You are not missing anything. Wheat free food tastes way better, and I feel better eating it. I can't wait until this is over.

I believe I am also probably sensitive to soy. When I went gluten-free and ate the soy waffles, I immediately got diarrhea and severe acne clusters. Anyone know what all the GI can test for during the colonoscopy? Soy, peanuts, lactose, etc.?

Also, I was wondering if most peoples' symptoms after not eating wheat and then eating lots of wheat is this subtle. I expected power diarrhea right away, but feel pretty good so far. Is this typical of celiacs?

Hi Jala,

Don't worry the diarrhea will come. :blink: I had to do a gluten challenge over the holidays last winter. It made the eating part of the holidays much simpler, but I did not enjoy it because I felt so bad. I was like you, I started with the bloating and constipation, but the diarrhea did eventually happen. I was back on gluten for 8 weeks, and I still tested negative on the biopsy.

Make sure your doctor checks the cellular level of the samples, and not just the villi. If the villi are not flattened or just look slightly abnormal, then they need to count the number of intraepithelial lymphocytes. Most doctors do not do this. It has to be specifically ordered at the time the biopsies are sent to the lab, but without it, if the villi are not damaged enough then the test is not going to give you accurate answers. I found this out too late to help me, but hopefully it will help you. It is called a CD3 stain and anything over 20 intraepithelial T-lymphocytes / 100 mucosal cells is damage consistent with Celiac. Please ask your doctor to do this before the biopsy, so that they have time to find out what to order if this is not standard procedure for them. And then make sure they do it! Other wise you are suffering for no reason right now.

God bless,

Mariann

Yes - the more input the better! And, the more I read the more it appears that there is no one description of someone with celiac disease. That must also be why there are such varying suggestions from the technical and medical professions about how much gluten is sufficient for valid test results. Like you, Jala, my husband had decided to do 5 weeks (which, in his case, was a crafty compromise between the 4 and 6 week suggestions he'd heard - but still pretty arbitrary), and that may just not be good enough from what others have experienced. Obviously, a personal decision has ti be made at some point!

Best,

Kaylee

    • WOW.  That looks eerily familiar.  Last December the temporary provider here at my local (rural) clinic gave me doxycycline to experiment with, but it was a mere ten milligrams.  Lol, no wonder it didn't help!  I'm glad you're feeling better.
    • I got cross contaminated some time ago & the rash came back pretty badly. I've attached a photo taken on June 11th of my back. It was also in my scalp, around my neck, on my front, shoulders, inner wrists and more.   Tonight I am not itching at all! I haven't itched all day long!!!! I can't take Dapsone because I'm allergic to sulfa drugs & Dapsone is a sulfa drug. Obviously that means I also can't take any of the other sulfa drugs that are used to treat dh after Dapsone is not an option. After those comes tetracycline. I really needed some relief! I began researching the dosage & particulars on tetracycline for dh. Extensive & exhaustive research did not pan out. The best I could find was treating Bullous phemphigoid. That said something like 500mg of tetracycline 4 times per day and about an equal amount of niacinimide. I really didn't want to take that much medication and in such strong doses. So my doctor (my PC doc) & I began experimenting. We tried Doxycycline 100mg twice a day. It seemed to be helping some but it just wasn't enough. Then we upped it to 200mg Doxycycline twice per day. It has taken about 5 days of that & I sit here not itching all day for the first time in a long, long time! This may not work for everyone. I did want to post it though as it is, at present, working for me. I am not thrilled at taking it but I have toughed this rash out before for years with no meds and I just couldn't do it again.
    • I laughed out loud at the 'little notebook' comment!😂 It has been interesting to see how much progress has actually been made over the past 10 years that there is even a notebook to be offered or a restaurant to eat in that will accommodate our 'allergy'. 10 years ago I feared that I would never eat in a restaurant again.  But the notebook comment is spot on.  Hopefully within the next 10 years restaurants will evolve enough to offer us a menu that clearly lists the delicious and extensive offerings that they have lovingly prepared just for us...and not just an ingredient list with nutritional values that take longer to read than War and Peace.   I am grateful that there are places to go that at least make the effort.  Who knows?  Eventually there may be restaurants which will have to offer menus with GLUTEN options available!
    • Thanks for posting this Adrien, it's a great list and I and others will appreciate the effort and the thought behind it. I loved my time in Malaysia and I'm glad I sampled all the food I could whilst I was still on an unrestricted diet. The good thing is that, like you say, some of the nice Malay foods are still ok. As a backpacker I survived on a lot of nasi goreng and laksa, nice to think if I return there I could still do the same Terima kasih!
    • I have posted on here before. DQ2, brother with celiac, DGP iGA was the only mildly elevated test. Was gluten-free so did 6 week challenge last winter. Negative biopsy. I am gluten-free now but do go out to eat. Prior to the challenge my health was good. Since then I have: Chest pain, pain between shoulder blades, periods of shortness of breath, heart palpitations, one instance of a heart arrythmia episode, neck is tender to touch on one side (they kept saying sinuses or TMJ which my dentist vetoed) ear ache, bowels never sink. Numbness and tingling. Blood pressure variations. Could be doing chores and feel dizzy and it might be 84/52.  not super low, but not typical for me if I'm running around the house.While other days I am mildly hypertensive. Recently lost 5 lbs in 8 days without trying. Recently electrolytes were low, alkaline phosphatese was low. Ferritin started dropping so started liquid iron 2-3 times per day 4 months ago. Primary watching that, I am not anemic but we are nowhere near iron overload either.  GI doc was a dick. Did not even know DGP replaced older tests and he was very condescending When I begged him for help recently and told me to get a second opinion which is exactly what I plan on doing.  I now have pain in my upper GI area. It is tender to touch. I had my gallbladder out in 97 along with a stone and infection in my bile duct. It hurts in this area. Pancreatic enzymes look fine, liver enzymes fine. Pancreatic ultrasound fine. I will now be doing a EUS Soon to look at bile duct, pancreas and liver.   so a typical day for me is that I might feel fine for a while and then suddenly feel like I'm going to pass out. really dizzy, numbness in odd places, like my body has been hijacked. I will typically eat a bunch of food something high protein and in about an hour or so I start to feel better. However, then my upper stomach starts to hurt in place of the passing out feeling. blood sugars are also normal. After getting the " it must be panic attacks" and condescending looks a million times my primary finally ordered an ultrasound of my sore neck and there is an abnormality in my thyroid which she says looks like possibly Hashti's. Except for one time, all my serum TSH tests were normal. We have more blood work on Monday. As I have not put on any weight and there are other symptoms that are closer to Graves.  Has anyone else had any thyroid issues that followed doing a gluten challenge?  where is your stomach pain? Do you have it above or below your belly button? Mine feels like it's in the pancreas area, like 2-3 inches above the belly button and when I push on it it's tender, but not all the time. sometimes i feel it in my back.
