Could an egg allergy cause a false positive on blood screening test?

Rate this topic

Recommended Posts

Hello. I am new here and am so appreciative to find this forum, I hope my question does not sound silly. We are currently waiting on a biopsy later in the month for my teenage daughter who tested positive on the blood screening test. She was tested only because she was in the Neurology ward being tested for decline in reading and verbal comprehension and finding herself zonning out. Her MRI and EEG were normal. They did a whole lot of bloods. They showed she was anemic and also tested a slight positive for the antibody test. I can understand the Iron levels being low as she mainly ate fish and chicken and not much red meat. She then went on Iron tablets for 4 months and ate red meat 4 times a week. She seemed to be abit better after that but still found herself with symptoms. The Gastroenterologist has ordered a biopsy to be done for Celiacs. She has no physical symptoms of stomach or bowel problems. She is being assessed soon for ADHD and is already diagnosed with annaphylaxis to Egg, Auditory Processing Disorder and Anxiety Disorder. My question is, is it anyway possible the egg allergy could interfere with the blood results causing a false positive? I guess I am just worried and hoping for anything and grasping at straws. I did read here on the forum someone mentioned that a milk allergy could affect the blood results. I should really make an app with her doctor to ask and will do. But just really worried and hoping someone can shed some light on this with past experience or knowledge and hoping there is a possibility it might be the case to alleviate abit of stress until I can see the doctor. Thank you for taking the time to read this.

I believe that anaphylaxis involves a different immune system pathway than does celiac disease or other food intolerances.

Very many people with celiac disease have few or no GI distress, at least in the beginning. We call that "silent" celiac disease.

Has your daughter been tested for "pernicious" anemia? This is where there is a lack of something called "intrinsic factor" necessary for the absorption of B12 by the gut which in turn results in anemia, since B12 is a necessary link in the chain of metabolic events responsible for the uptake of iron into the blood. It is extremely common for celiacs to be low in B12 and anemic and I believe the damage to the small bowel caused by celiac inflammation also may be partly responsible for substandard production of intrinsic factor.

Thank you Trents very much for providing this information. Im not sure if my daughter has been tested for pernicious anemia but the Gastroenterologist did say that her B12 is low aswell. I initially thought it could be because she was never a big red meat eater. After reading your reply I have looked up B12 foods. My daughter drinks loads of milk and loves cheese and fish so she shouldnt be low in B12 due to any lack of dietary foods. The Gastroenterologist app was a zoom meeting during our strict lockdown in Melbourne, it seemed so strange and new to me at the time because I had not done a zoom before. Due to this unfortunately I didn't ask very many questions and I wish I did. With the egg anaphylaxis I can also undertand what you are saying about the different immune pathway.  It all makes sense to me now. Also I should get out of my mind that her having no physical bowel symptoms means she won't have Celiacs.  I now feel better about her having this biopsy, and that it is really neccessary to go through with the procedure as she probably does have a high chance of having celiacs. If she does have Celiacs, and I can see now it is likely, and her bowel is damaged without symptoms, then it is lucky she has been tested without having bowel symptoms because I dont think the local gp would ever have done the test. Thank you Trents you have made me realise that having this biopsy is so important and definitely neccessary. All the best for your journey in this too. Much appreciated.

You are most welcome and I hope what I have shared will prove to be of help as you seek to get a handle on your daughter's health issues. Concerning the anaphylactic reaction to egg protein the same way as you would a bee sting in so far as how it engages the immune system.

Tracy66,

I'm concerned about the decline in your daughter's brain function!  

Celiac Disease causes malabsorption which results in malnutrition, vitamin and mineral deficiencies, which can have the same results, the decline in brain function your daughter exhibits.  I am not a doctor.  I have experienced severe vitamin and mineral deficiencies.   

Thiamine (Vitamin B1) deficiency can cause changes in brain function such as the ones you describe.  It's called Wernicke's Encephalopathy.  It's usually seen in alcoholism, which is why my doctors missed it in me.  When my doctors asked me if I drank alcohol, I explained alcohol makes me violently ill so I don't drink.  My doctors shrugged their shoulders and wrote me off as a hypochondriac.  My doctors had not recognized Wernicke's outside of alcoholism.  They were even more clueless about Celiac Disease.  

I'm a microbiologist.  I had learned about vitamins at university.  I researched and started supplementing with thiamine and the other B vitamins and minerals.  

Those things your daughter is experiencing could be due to Thiamine deficiency.  I had similar problems, ADHD, anxiety, problems understanding what was said to me, and more besides.  

 Your daughter improved slightly with inclusion of red meat in her diet.  Red meat is a good source of thiamine.  Thiamine is water soluble and can not be stored for long.  A deficiency can develop quickly if you're not getting enough thiamine.  

The best test for thiamine deficiency is the erythrocyte transketolase test.  

The treatment for thiamine deficiency is high dose Thiamine which is safe because thiamine has no toxicity.  An IV of high dose thiamine can be given by doctors or over the counter thiamine supplements can be used to correct a deficiency.

It's rare to have a single vitamin deficiency.  Deficiencies usually occur in several vitamins because they all work together.  Testing for vitamin deficiencies is part of proper follow up care for Celiacs.  

I want to express a sense of urgency because Wernicke's can progress to Korsakoff's syndrome which can cause permanent damage.

I'm not a doctor.  We can't give medical advice.  But I urge you to discuss this possibility with your doctor.

Tracy66, knitty kitty gives good advice. Many of the medical condition spinoffs from celiac disease are nutritional deficiency related. The damaged villi in the small bowel causes reduction in the ability to absorb vitamins and minerals. Also, I wanted to say that celiac disease is not an allergy. It is an autoimmune condition. That can be a little difficult to grasp at first since there is a food trigger involved like we normally would connect with an allergy.

Tracy,

Try have her take some Riboflavin....it has been shown to help Anemia.

It will turn her urine Yellow after a few days....

It is what is in a B-Complex that changes the color of your urine.

https://pubmed.ncbi.nlm.nih.gov/31318024/

Better yet jut take a B-complex.

IF she complains her urine is "glowing" then she has enough Riboflavin aka Vitamin B-2.

I hope this is helpful but it is not medical advice.

Knitty Kitty thank you! I have written the name of the test down. It is very concerning. Daughter has an app, first app with a new specialist, a devolpmental/behavioural Paediatrician this Monday. She is 13. I will definitely ask him to pursue this test. It must of been awful for you to have to pursue the issue of comprehension problems and other relating symptoms, and have doc shrugg you off. My daughter says cannot understand what her teachers are saying and if she does then she forgets it very quick. She forgets a lot of things said to her by anyone and also what she has done. She will not watch movies, read or listen to music at all. I think her motor function is ok. Her grades have fallen in the last 2 years. It's got to the stage where we have to say something using the least amount of words to her so that she understands what we are saying. She says her friends help her at school to get by, which is so lovely they care and I had no idea until she came to me all upset saying it started a couple of years ago and that its getting worse. I did think she wasnt listening and was trying to encourage her to listen. The positive Auditory Processing Disorder tests she had was thought to be the issue and also now ADHD is being considered. But now that Celiacs is possible and I can now see how it can cause these symptoms through vitamin esp thiamin deficiency I am definitely asking for this blood test and also a full vitamin blood test if that exists. Waiting for this biopsy Feb 18th, so have to keep eating gluten, but if in the meantime bloods do show deficiency then it would be much better for them to organise supplements she needs now. Thank you Knitty Kitty and thank you to Trents for your helpful information. I did think Celiac was an allergy and I thought it could cause autoimmune diseases, but I didn't know it was an autoimmune disease. I am much more on to this now knowing a lot of her symptoms are related to Celiacs. Only good thing is if my daughter can have relief from all these issues from diet and supplements then that's better than being medicated. She has in the past had fluoextine for severe anxiety and although it definitely helped it was a very last resort and I hated her being on such a drug.

Poster boy, thank you too! A B complex is a great idea!. It cannot hurt her and after learning more about Celiacs relating to her symptoms, I feel it's urgent to find out what vitamins she needs for supplements. I was going to wait for the biopsy to see what Gastroenterologist says but now I'm going to pursue this with her new Peadiatrician we see Monday and get the ball rolling with helping any deficiency. Thank you so much.

I would just like to say I am so grateful I have joined this forum. It's my first time I have ever joined a forum. The help I have received in understanding the nature of Celiacs has been invaluable to me. Due to all of your information you have helped me realise that something can be done even before she is diagnosed.  Having tests for vitamin deficiencies in the meantime before a diagnosis can help her get the right supplements she will need now. Knowing what to ask for helps so much. Also now I undertand more on Celiacs and how much her symptoms relate.

Before I joined I had convinced myself the biopsy was more of an annoyance, and was overwhelmed by one more thing to pursue. I thought the egg allergy could have changed the blood results to a positive. But if all her symptoms are related to Celiacs, and diet and supplements can be the answer to most of her problems then I don't feel so overwhelmed with having to purse this. Thanks so much. Will keep posted.

Tracy66,

I found one more article for you.

"Neurological, Psychiatric, and Biochemical Aspects of Thiamine Deficiency in Children and Adults"

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6459027/

 

Check into the Autoimmune Paleo diet so you'll be prepared when given permission to go gluten free after all testing is done.  This is my favorite book for newbies.

https://www.thepaleomom.com/books/the-paleo-approach/

And, remember, Celiac Disease is genetic.  All first degree relatives should be tested.  (Parents, daughter, siblings, etc.) So get tested yourself, too, Tracy! 

Hope this helps!

Tracy66, also be aware that serum vitamin and mineral level testing may not tell the whole story since they don't measure what is actually getting to the tissues. Deficiencies can also be masked in some cases by supplements. A case in point is a B12 deficiency being masked by folate supplementation. Really, it can be better to observe the effects on the body and on behavior when it comes to diagnosing deficiencies but most docs are not well versed in this kind of diagnosis and it is just easier for them to send a sample off to a lab and be done with it. When it doubt, supplement. The water soluble vitamins are safe so there isn't much concern for overdosing. Be more careful with fat soluble vitamins and with minerals. 

Another case in point is calcium. Serum calcium levels typically remain stable even when a diet is deficient in calcium since the body just takes it from the bones.

Trents I see what your saying about trying out the water soluble vitamins as they can't turn toxic and behaviour can be determined for success of supplement.. Thanks for that. Her Dad and I have just now decided to go out and get get her a good B Complex vitamin like Poster Boy suggested. I will also ask for the specific thiamin test Knitty Kitty suggested on Monday at Peads.

Also interesting you told me Celiacs is actually an autoimmune disease. I had endometriosis which can be linked to autoimmune diseases. It caused antiphospholipid syndrome for me which is an auto immune disease.. Interestingly after years of medical intervention endometriosis kept coming back aggressively and antiphoslolips remained.. 8 years of IVF on top of that and no pregnancy. I was to be on heparin if I ever did get pregnant due to the antiphospholipid disease.

I saw a Chinese medicine doctor. In one year of her therapy she reversed both the diseases which showed up on my annual laproscopy for Endometriosis and also showed up as negative on bloods for the antiphosoholiid syndrome. Doctor asked what had changed in that year. He dismissed the fact that Chinese medicine had anything to do with either of the results. I was pregnant with our daughter straight after that. The heamatology doctor told me there was no need for heparin as "for some reason" I am now negative. 

Knitty Kitty the Gastroenterologist did say for direct relatives to be tested. I was going to wait until a definifite diagnosis from Jade our daughter. But now I will book myself in for a test, her Dad said he will do one too. Monday will be ringing up for blood test.

I am also thinking of speaking to the Chinese medicine doctor to see if she can help with Celiacs if diagnosed. I cannot say enough how much she helped, particularly the auto immune disease that I had. If any of you are interested in giving it a try. It was accupuncture and Chinese herbs made up looking like it came out of a forest that I had to cook.

Tracy66, just be careful and get vitamins and supplements that are gluten free. Not sure where you live but Costco is a great source for gluten-free vitamins and supplements through their Nature Made line if your are in the USA and near one.

Thanks Trents. We are in Melbourne so have Costco. Hubby has already gone to get a B Complex and come back with Cenovis. It says no added gluten so hopefully ok.

Tracy,

Wait until after the test for vitamins on Monday.  If you start supplementing now, you will invalidate the tests.  The tests will measure the supplements in her system.

You should talk to your doctor before administering thiamine yourself.  The doctor may wish to administer an IV of high dose thiamine and witness the results.

Thanks Knitty Kitty. Hubby went out to get a B Complex vitamin already and we have given her a tablet. But its only one. Can hold off to Monday now and tell Paed what she has had.

Also Trents we are in Melbourne, Australia. Hubby pointed out there is also a Melbourne in USA. But we still have Costco in Australia. It's a good store.

Hi Tracy,

Here is an article listing the tests they can do for celiac disease.  The usual screening test is the ttg IgA.  But there are other tests for different types of antibodies also.  Some people's immune systems don't even make IgA antibodies so it is better to get all the different types of antibodies tested.

https://celiac.org/about-celiac-disease/screening-and-diagnosis/screening/

Allergies are an IgE reaction, not IgA or IgG like celiac is.

The antibody tests all have result ranges that vary by each lab.  So if you get her test results make sure and get the lab ranges too.


Proverbs 25:16 "Hast thou found honey? eat so much as is sufficient for thee, lest thou be filled therewith, and vomit it."

Job 30:27 My bowels boiled, and rested not: the days of affliction prevented me.

Thyroid cyst and nodules, Lactose / casein intolerant. Diet positive, gene test pos, symptoms confirmed by Dr-head. My current bad list is: gluten, dairy, sulfites, coffee (the devil's brew), tea, Bug's Bunnies carrots, garbanzo beans of pain, soy- no joy, terrible turnips, tomatoes, peppers, potatoes, eggplant, celery, strawberries, pistachios, and hard work. Have a good day! 🙂 Paul

Thank you GFinDC for the link. It describes the testing well.

Also I remembered allergies were Ig something that's why initially I thought it could alter the test result., Of course now you mention it allergies are IgE not IgA.  Thank you for clearing that up for me. Also I have since learned that Celiacs is an auto immune disease which, until I joined this forum was thinking it was an allergy. 

I am very intetrsted in getting the test results of all her bloods now. Will see if GP will send them to me,as the next time I'm seeing Gastroenterologist at the children's hospital will be when she gets her biopsy. Thanks again for posting helpful link and info.

Posterboy,

Lots of sound advice .The only caution I want to express is with taking a B- complex vitamin. Its better to have your B levels tested guest before taking, especially in young developing children as too much can be harmful. As an adult ( before being diagnosed with Celiacs) I thought a B- complex was a good idea as I was feeling tired all the time. The headaches and stomach aches from taking that vitamin were awful- I never had headaches before. I stopped and shared that with my Dr. She told me never to do that again, with any vitamin really as it could be harmful - even with Vitamin B. She tested my levels and I was only low in B-12. Her and my neurologist told me to only take a B-12 without any other vitamins or minerals added and the kind that is absorbed under the tongue. Since then no headaches, no stomach aches. Bottom line not all vitamins are treated equal and more is not always best.

It is always best to get a professional opinion before taking medications and supplements recommended on the Internet. We should be mindful of the things we put into our mouths, realizing there may be a cost that the kidneys or liver may (may) have to pay. Sound thinking, @Placey.


Diagnosed with Celiac in 2010. Diagnosed with sleep apnea 2018.

You are welcome Tracy.  You are not alone there, many people think that celiac is an allergy.  Sometimes people with celiac will tell their server at a restaurant that they have a gluten allergy.  That is far easier for people to understand than an auto-immune disease, especially people with no medical background like most restaurant workers.

The link below talks about supplements for celiacs.  I've had problems keeping my vitamin D levels up in the past.  I take a vitamin/mineral combo that includes boron and calcium and vitamin D.  Boron is important because it increases the length of time vitamin D is retained in the body.  It also helps in the storage of calcium in bones.  Your doctor can give advice based on the testing they do.

The good news is if it is celiac causing the issues, she has a fine chance of fully recovering.  It may take some time, but once her intestine heals and can absorb nutrients efficiently again, her body can recover.  Healing the gut can take months though as the immune system is slow about giving up a fight.  And any tiny bit of gluten can spark an immune system flare.
