Chances Of False Positives? Newly Diagnosed.


LRM91

Recommended Posts

LRM91 Newbie

I've always had stomach issues and they have never been diagnosed. Doctors always thought it was something like colitis, even weather changes and so on or foods I eat (too much junk food?) but they could never find anything. I went to my doctor for a regular checkup and she did blood work on me and told me that I have celiac. I wasn't even sure what it was at the time. A lot of it makes sense to me on my sickness and maybe I'm in denial or can't think straight but I don't remember all gluten items making me feel sick? Unless I was naturally used to stomach cramping and it didn't hit me? But some foods like cereal made me feel hospital sick, but this gluten free cereal I'm eating is fine. But wouldn't all gluten make you feel sick with this disease? I'm really new to this. She said something I should be at a 3 and I'm going past 11 (something with my blood I think) and it's really really bad and I have vitamin deficiencies and says it caused me to be anemic. Does anyone know what those numbers mean? And if false positives are common? :/

no, sweetie, false positives are not common (false negatives, however, are maddeningly common) welcome to the best club you never wanted to join.  take a deep breath and read the newbie 101 thread in the 'coping with' section.  the good news is:  you are on the road to feeling better.  we have all been where you are now:  don't know what to eat, how could you have this and not know, etc...  but you will be ok.  welcome to the board.  good luck.  we are here to help if you need it :)

Not all gluten related items made me sick all the time. Before diagnosis I ate gluten all the time and wasn't sick all the time, a lot of it, but not like when I eat gluten now. I only had really bad stomach issues a few times a year, pain related that is. Other wise all it was was constipation for me. You will be in denial for a while, you're giving up something that you had no clue was making you sick. It's a grieving process.

We can better explain your labs if you have the testing and results in front of you and can post them. I was a lab tech for 16 years but I don't know what labs you had drawn to explain what the results mean.

Like Arlene said, read the newbie section. It gets easier and there are plenty of helpful people on here

Thanks (: I never got a copy of my papers for results I'll ask her again when I see her in a month. I was in shock so didn't really know what to say. But she said I'm highly intolerant and need to stop eating gluten asap. I'm glad there is a forum for it though. I was also told to go on the paleo diet the best I can. Ahh so many changes >_<

beth01 Enthusiast

I'm not sure really what they told you about Celiac, but you can't eat gluten at all, have to stick to a 100% gluten free diet. It isn't so much of intolerance as it cause an autoimmune reaction in your small intestines, gluten destroys the villi. A breadcrumb is enough to cause the autoimmune reaction. Sure it's an intolerance, it makes you sick, but it's so much more. I don't know much about paleo, but I would try and eat as clean/whole as possible ( the less processed foods, the better), cut out dairy initially ( most celiacs are lactose intolerant due to the enzyme to digest lactose is excreted from the villi that we don't have due to damaged intestines)and keep a food and symptom diary. Learn all you can. It seems so over whelming at first, but it get's easier.

False positives and negatives are rare, contrary to other's assumptions 1-3% of the time:

The false readings often come in when you have low IgA or IgG levels or haven't eaten gluten while testing from what the U of Chicago website says.

Welcome to the board.  :)  I hope you start feeling better fairly soon.

Based on what I have read and learned, false positives are rare (usually 5% or less of all positive results) but false negatives are not and can occur in 5 to 60% of test results depending on the test (most being below 25%).

Not only that Nicole, but people also don't produce the antibodies at the same rate or the same time of their illness. I often wonder since I was sick for 37 years and my tTg was only 37, would I have tested positive a few years ago? We will never know, unless they follow gene positive people from birth until diagnosis ( should they become celiac). I think it would be easier to find out how many licks it takes to get to the center of a tootsie roll tootsie pop.

LOL  No one can just lick those things.  ;)

 

The changing lab number phenomenon seems to be true of celiac disease, and true of other diseases too.  My thyroid tests were boarder line high for many years before finally going high enough for doctors to be concerned, even though I felt no worse when it was quite high compared to barely elevated.   :rolleyes:

Yeah, I know which makes the discrepancy confusing... I wonder where they got their numbers from because the medical journals and texts on celiac disease don't back up those low numbers. Especially their assertion that false negatives (1-2%) are more rare than false positives (1-3%) - that is the only place I have ever seen that stated.  I wonder if it was a typo or something...

 

Most studies on those tests will dispute those stats.  False positives are rare, but false negatives happen more than we'd like.  

 

I like to compare celiac disease tests to a pregnancy test. It is possible to get a false negative (when you test too early - like with early celiac disease) but it is very rare to get a false positive. A positive is generally a positive for celiac disease.

 I was also told to go on the paleo diet the best I can. Ahh so many changes >_<

 

I was working towards converting to paleo for the last year... slow process because there's a lot of foods I wasn't willing to give up yet... like dairy and nachos :) . Anyway, the kids started school and everyone was being so rude with my paleo choice, I started consuming grains again... including wheat, many pizza nights since my kids are in sports. Ended up with enough GI issues that I went to the ER one night because I couldn't sleep anyway. A month later, diagnosed with Celiac. Once my endoscopy is complete, I am going autoimmune paleo to help heal my gut. Though, I'm not sure I will remain paleo forever because of, well... dairy and nachos, lol

LRM91 Newbie

I didn't even know there was an autoimmune paleo diet, I just looked it up it sounds super interesting. Nachos and diary are the best! I haven't had any milk (besides when cooking and I had an upset stomach) so I've been using almond milk but I'm not sure if cheese is something I can give up. I literally feel like I live for cheese haha. I've found some good sites for recipes for paleo that don't make it seem TOO bad which is most likely better than all the processed gluten free stuff I've been eating. I'm usually super busy so never have time to meal prep. But I'm sure you can find a paleo version of nachos ;) I found one for Alfredo and it sounds super weird and interesting it's worth a try. It seems like you can make a paleo dish with anything.

In my situation I've had issues for 3 1/2 years but nobody could ever find anything. I've recently started getting blood when I go to the bathroom. I felt like none of my doctors ever took me seriously though and always acted like I had a stomach bug all the time or something seasonal, or they thought colitis but never did additional testing. But how I found this out was just doing my regular gyno exam and she drew blood, I met up with her a month later for my results she said levels were extremely high and I'm most likely all puffed up and I can never have gluten again, go on the paleo diet and see her in a month and that was that. Is there any additional testing I should be doing to see the damage? Or did that most likely show in my blood work?

Because I am soy and corn intolerant on top of Celiac, I don't follow The Paleo diet regularly but I get alot of recipes from Paleo , They are Grain free. They call it the Cave Man diet.

I love cheese too... It may or may not be the reason behind what sent me to the ER... that is assuming some of my problems are just constipation. I was on a nacho spree leading up to that visit, lol. I just ordered a book called the "Paleo Approach: Reverse Autoimmune Disease and Heal Your Body" and the "Paleo Approach" cookbook..  I have been following her on FB for awhile because I knew something was wrong with me, but any time I'd mention anything about it, it was brushed off. "There's no pill to fix <insert symptom>..." kind of responses. Or "you're probably just constipated, here is a prescription for lactulose". I had just intended to "heal" myself until I found a doctor who thought we should test for Celiac. I haven't tried too many paleo conversions, I made banana bread with almond flour and it was good, but definitely not the same as wheat flour banana bread. I attempted to use spaghetti squash in place of pasta, but it wasn't as satisfying. I guess now though, there won't be much reason not to try more recipes  :) .

"I don't remember all gluten items making me feel sick? "

 

stick with 100% gluten free. You will eventually feel better all the time. You will eventually realize that you are very used to being pretty sick a lot.

 

I have been doing this for 20 plus years. Right now my biggest pet peeve is the idea of needing to "feel sick" when gluten is consumed. People ask me this all the time, "So how do you feel?? Was there gluten in that?". It damages the intestine regardless of any symptoms. Depending on which part of the bowel get the damage, it could take weeks to months of damage before we notice.

      Hello all! My life in the last five years has been crazy. I got married in 2020 at the age of 27, pregnant with our first child almost two months later, gave birth in 2021. We had another baby in April of 2023 and our last baby this March of 2025. I had some issues after my second but nothing ever made me think, "I should see a doctor about this." After having my last baby this year, my body has finally started to find its new rhythm and balance...but things started to feel out of sorts. A lot of symptoms were convoluted with postpartum symptoms, and, to top it all off, my cycle came back about 4m postpartum. I was having reoccurring migraines, nausea, joint pain, numbness in my right arm, hand and fingers, tummy problems, hives. I finally went to my PCP in August just for a wellness check and I brought up my ailments. I'm so thankful for a doctor that listens and is thorough. He ended up running a food allergy panel, an environmental respiratory panel, and a celiac panel. I found out I was allergic to wheat, allergic to about every plant and dust mites, and I did have celiac. I had an endoscopy done on October 3 and my results confirmed celiac in the early stages! I am truly blessed to have an answer to my issues. When I eat gluten, my brain feels like it's on fire and like someone is squeezing it. I can't think straight and I zone out easily. My eyes can't focus. I get a super bad migraine and nausea. I get so tired and irritable and anxious. My body hurts sometimes and my gut gets bloated, gassy, constipated, and ends with bowel movements. All this time I thought I was just having mom brain or feeling the effects of postpartum, sleep deprivation, and the like (which I probably was having and the celiac disease just ramped it up!) I have yet to see a dietician but I've already been eating and shopping gluten-free. My husband and I have been working on turning our kitchen 100% gluten-free (we didn't think this would be so expensive but he assured me that my health is worth all the money in the world). There are still a few things to replace and clean. I'm already getting tired of reading labels. I even replaced some of my personal hygiene care for myself and the kids because they were either made with oats or not labeled gluten-free. I have already started feeling better but have made some mistakes along the way or have gotten contamination thrown into the mix. It's been hard! Today I joked that I got diagnosed at the worst time of the year with all the holidays coming up. I will just need to bring my own food to have and to share. It will be okay but different after years of eating "normally". Today I ordered in person at Chipotle and was trying not to feel self-conscious as the line got long because they were following food-allergy protocols. It's all worth it to be the healthiest version of myself for me and my family. I would be lying if I said I wasn't a little overwhelmed and a little overloaded!  I am thankful for this community and I look forward to learning more from you all. I need the help, that's for sure!

      On the AIP diet, all processed foods are eliminated.  This includes gluten-free bread.  You'll be eating meats and vegetables, mostly.  Meats that are processed, like sausages, sandwich meats, bacons, chicken nuggets, etc., are eliminated as well.  Veggies should be fresh, or frozen without other ingredients like sauces or seasonings.  Nightshade vegetables (eggplant, potatoes, tomatoes, peppers) are excluded.  They contain alkaloids that promote a leaky gut and inflammation.  Dairy and eggs are also eliminated.   I know it sounds really stark, but eating this way really improved my health.  The AIP diet can be low in nutrients, and, with malabsorption, it's important to supplement vitamins and minerals.

      Thank you for responding and for prayers.  So sorry for your struggles, I will keep you in mine.  You are so young to have so many struggles, mine are mild by comparison.  I didn't have Celiac Disease (celiac disease) until I had my gallbladder removed 13 years ago; at least nothing I was aware of.  Following surgery: multiple symptoms/oddities appeared including ridges on fingernails, eczema, hair falling out in patches, dry eyes, upset stomach constantly and other weird symptoms that I don't really remember.  Gastro did tests and endoscopy and verified celiac disease. Re heart: I was born with Mitral Valve Prolapse (MVP) and an irregular heartbeat, yet heart was extremely strong.  It was difficult to pick up the irregular heartbeat on the EKG per cardiologist.  I had Covid at 77, recovered in 10 days and 2 weeks later developed long Covid. What the doctors and nurses called the "kickoff to long Covid, was A-fib.  I didn't know what was going on with my heart and had ignored early symptoms as some kind of passing aftereffect stemming from Covid.  I was right about where it came from, but wrong on it being "passing".  I have A-fib as my permanent reminder of Covid and take Flecainide every morning and night and will for the rest of my life to stabilize my heartbeat.

      When I accidentally consume gluten it compromises the well-being of my heart and arteries. Last time I had a significant exposure, about six months ago, I had AFib for about ten days. It came on every day around dinner time. After the ten days or so it went away and hasn't come back.  My cardiologist offered me a collection of pharmaceuticals at the time.  But I passed on them. 
    • klmgarland
      So I should not eat my gluten free bread?  I will try the vitamins.  Thank you all so very much for your ideas and understanding.  I'm feeling better today and have gathered back my composure! Thank you kitty kitty   I am going to look this diet up right away.  And read the paleo diet and really see if I can make this a better situation then it currently is.
