Questions About Lab Tests...

I saw a GI Dr today and I'm curious about some lab tests I'm getting done.

One is for Lactose Intollerance and it's a blood test. What does this entail and how does it work in comparison to the breath test?

How do they test for Bacterial Overgrowth?

Has anyone done an upper GI x-ray where you drink barium? What was this like?

Finally I'm getting a Dexa scan as well, what's this like?

I have a bunch of other tests, though I know about them.

Oh and it still seems like the GI Drs don't know much about Microscopic Colitis :( Still seem to be grasping at straws. Talked about high fiber, pepto bismol and endocort (sp). The usual. Seem to be even clueless about celiac/gluten sensitivity. Didn't seem very impressed with the stool testing other than the gene test, nor did they seem to care much about the IgG test. Talk about heads in the sand. :(

Well, I can help with a couple of your questions...I also had the lactose intolerance blood test. My understanding is that the blood test is for adults and the breath test for children (my daughter had the breath test). Also, while any lab can draw for the blood test, it is much more difficult to find a place that will do the breath test (we had to travel an hour to a major children's hospital to have it done). Anyway, you can't have anything to eat or drink after midnight the night before - they take blood and then you drink a solution of lactose mixed with water (tastes a bit chalky and like very watered down orange koolaid). Then, blood is drawn every half hour for, I think, two hours. It took a couple days to get the results. I had a mild stomach ache after. I've also had an upper GI with barium. They take a bunch of xrays at first and then take a bunch of xrays with you in different positions (standing, sitting, etc.) while drinking barium so they can watch it go down your esophagus and into your stomach. The drink is cherry flavored and definitely chalky tasting - it doesn't taste good but it wasn't as terrible as I was anticipating either. Good luck!

Thanks, I'll have a bit less anxiety about it all now.

I'm curious, what were the results of the lactose test?

I've never had the lactose test done...would be a little worried about it, knowing how I do with lactose (probably would be running for a bathroom before they could do a blood draw!) ;)

My Barium test involved no food or drink after a certain time the evening before. Right before the test I had to quickly injest a powder followed by water (the powder instantly fizzed while I swallowed.) Then I had to swallow the barium (they can add different flavours to it.) Didn't taste too bad. Then I was intructed to move into different positions on an xray table that moved from vertical to horizontal position...essentially the xray records the movement of the Barium through your system. Once the test was over I was instructed to drink lots of water throughout the day to help pass the barium out of my system.

The results of my lactose intolerance test were very abnormal - I had suspected it for a very, very long time but my doctor wanted the test just to make sure. I had a mild stomach ache after the test but it wasn't nearly as bad as, say, if I had a piece of cheese.

Oh man, the last time I had cheese I was miserable. I even went for an Aged Cheddar that supposedly wouldn't contain any lactose. I suppose it could have been some other ingredient in the cheese as I suspect the Anneto (sp) coloring, but I've had Milk Protein Isolate (basically all that's left is whey and casein) and didn't see any problems there. Lactaid milk also seemed ok, still felt a bit off, but nothing like the cheese incident.

What sucked even more was that the day I had cheese was the day my mom came up to visit, I was pretty much on the toilet the whole time she visited after eating the cheese. :(

I can't tolerate any cheese (not even soy cheese because of thyroid problems) or lactaid milk or any other dairy at all and, really, the stomach ache I got from the lactose test was minimal. It really wasn't horrible and I was able to continue my day as usual. I think it really is a minimal amount of lactose that they use for the test. I understand that you're hesitant but, honestly, all I can tell you is that I can't tolerate any amount of dairy (even if it supposedly contains no lactose and/or use Lactaid pills) and I really wasn't that uncomfortable after (or during) the test. By the way, the amount that you drink is fairly minimal, too - like 6 or 8 ounces.

      Opinions on my test results/symptoms

      By BIg Nodge · Posted

      Hi, I have recently embarked on the gluten-free journey. I have what to me seems like a somewhat confusing set of test results and symptoms. I have been impressed by the accumulated knowledge and thoughtfulness as I browse this forum, so I figured I'd make a post to see if anyone can offer any insight. I know there are many posts like this from new users, so I have tried to do my baseline research first and not ask super obvious questions.  I'm 43, overall very healthy. No history of gluten sensitivity or really any of the classic GI symptoms. About three years ago I started to experience intermittent bouts of fatigue, chills/cold intolerance, and shortness of breath/air hunger (sometimes feels like a hollowness in my chest, hard to describe). The symptoms over time have become fairly significant, though not debilitating, I am able to exercise regularly and am fairly physically active, continue to perform well at work. But for example I have gone from someone who consistently ran hot, was always cranking the a/c, to someone who wears a down vest inside at work in winter and get chills if the a/c even blows on me in summer. I get tired and lose energy even when getting decent amounts of sleep, and have to have my wife take over on long drives that I could previously handle with no problems. More generally when I am experiencing these symptoms they seem to crowd out space in my mind for focusing on my family, my hobbies/activities etc, I sort of withdraw into myself.   I happened to be experiencing these symptoms during an annual physical with my PCP a few years ago, he observed post nasal drip and suggested it was allergies and that I treat it with claritin. At first it seemed to respond to claritin (though not zyrtex), but over time I became unsatisfied with that answer. There didn't seem to be any seasonal rhyme or reason to my symptoms, and I felt like I was on an endless loop of taking claritin, then stopping, not being sure if it was even making a difference. I did eventually get allergy tests and found modest allergies to dust and pollen, which didn't feel like a smoking gun.  I then started seeing a natural medicine doctor who was much more willing to explore my symptoms via testing. The first thing that came back abnormal was elevated thyroid peroxidase antibodies/TPOs, 137 IU/mL vs a reference range of <9. At the same time my thyroid panel showed normal thyroid hormone levels. So it appears my immune system is attacking my thyroid even though it is working fine. I got a thyroid ultrasound at the time, it was clear, but with some abnormalities such that they suggested I get is scanned again in a year. These are certainly risk factors for a thyroid autoimmune disease, though my thyroid seems to be working fine for now.  From here my doctor considered celiac due to the murky thyroid/celiac links, so we did a panel. Results were as follows: TT IGA <1 U/ml, TT IGG <1 U/ml, deamidated gliadin IGA 24.6 U/ml, deamidated gliadin IGG <1 U/ml, IGAs 170 mg/dL. Readings greater than 15 considered high by my lab for the first four, my IGAs are within reference range. So basically just the deamidated IGA popped, but my IGAs are normal. I also notice on the tests that my thyroglobulin was high, 86.7 ng/ml vs a range of 2.8 - 40.9.  My doctor suggested that it certainly wasn't conclusive for celiac, but it was possible, and likely that I have some sort of gluten sensitivity. She suggested going gluten free and seeing how I felt as opposed to doing a biopsy. The best theory I can come up with is perhaps I am a silent celiac or just have a gluten sensitivity that doesn't produce immediate GI symptoms, but is still doing damage and over time has caused leaky gut. So now gluten is getting into my blood, and my immune system is attacking it but also mistakingly attacking my thyroid.  So that's what I did, went gluten free in October. It's been about four months, and I am really not feeling any difference. I still get the same symptoms that come and go. My bowel movements may be a bit more regular, but it was never a major issue before so I would consider that a minor improvement. I know that it can take a while to see improvements, and I am going to remain gluten-free and see how I feel. But I am definitely questioning whether I really understand what is going on, and am open to any thoughts or suggestions from the forum. Sometimes I wish I just went ahead with the biopsy before going gluten-free. While I would certainly be down to start drinking IPAs again ahead of a biopsy, you know, for science, I feel like at this point I would be throwing away four months of work and am better off staying the course and seeing what happens. But I'm really not sure.  I know there is a lot of thyroid knowledge on these boards, along with the celiac expertise, so I'm curious if this resonates with anyone's experience. And I'm interested in what sort of timelines people have experienced in terms of feeling improvements for some of these non-GI symptoms like chills, SOB, brain fog etc. Thanks in advance.

      Testing positive for antibodies, are there visible changes to the colon that could be seen without a biopsy?

      By cameo674 · Posted

      Does it taste like black licorice?  It said it was chewable.  I do not like that flavor.     Since the burn at the back of my throat is there everyday, I usually only take something when it is unbearable and keeping me from ADL especially sleep.

      Nandos improper preparion celiac childrens food

      By Scott Adams · Posted

      Your concerns about Nando's cross-contamination practices are valid and important for the celiac community. It's disappointing that Nando's does not have stricter protocols for children's portions, especially given the risk of cross-contact with gluten-containing items like garlic bread. Cooking gluten-free items on shared surfaces, even if cleaned, is not safe for individuals with celiac disease, as even trace amounts of gluten can cause harm. While the adult butterfly chicken may be a safer option, the inconsistency in practices for children's meals is concerning. It's frustrating that Nando's headquarters did not take responsibility, but sharing your experience raises awareness and may encourage them to improve their protocols. Consider reaching out to celiac advocacy organizations to amplify your concerns and push for better standards. Always double-check with staff and emphasize the importance of avoiding cross-contamination when dining out.

      Mucus discharge

      I had this symptom when I was diagnosed. Are you sure that your diet is 100% gluten-free?  Many people with celiac disease, especially those who are in the 0-2 year range of their recovery, have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy. The good news is that after your gut heals (for most people who are 100% gluten-free this will take several months to two years) you may be able to slowly add some these items back into your diet after the damaged villi heal. This article has some detailed information on how to be 100% gluten-free, so it may be helpful (be sure to also read the comments section.):

      Confused with test results

      By Scott Adams · Posted

      Based on your results, it seems unlikely that you have celiac disease. A negative endoscopy and the absence of HLA-DQ2/DQ8 genes (the primary genetic markers for celiac) strongly suggest you do not have the condition. However, the elevated TTG-IgA (22) could indicate a temporary immune response or another issue, such as a different autoimmune disorder, intestinal infection, or even a lab anomaly. The presence of DQA1*05 alone is not diagnostic for celiac. Meeting with an allergist and GI specialist is a good next step to explore other potential causes for the high antibodies, such as non-celiac gluten sensitivity or other immune-related conditions. Keep a detailed food and symptom diary to help guide further testing and discussions with your doctors. Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.
