Negative Blood Tests

Hello to all. Even if I don't have celiac disease, I have learned quite a lot about it and I understand how much frustrating (even health-threatening considering cc issues etc) the ignorance of other people (and doctors <_< ) about this condition can be to many of you.

I just got the following blood tests :

=========Test======= Result======Normal Values

Anti-endomysial IgG------Negative-------------Neg <1/10

Anti-endomysial IgA------Negative-------------Neg <1/10

Anti-gliadin-------IgG--------9.8----------------Neg <25

Anti-gliadin-------IgA--------7.9----------------Neg <25

I have no insurance at the moment (I live in Greece by the way, national insurance is mostly useless here,unless you have a traffic accident(they treat u first) or you have cancer :o = no insurance needed- free care), so I just asked a specialist for a celiac blood test (she did the above). I have gi issues for the last 3-4 years but my main concern is some neurological and muscle issues I have since I was a teenager ( I was told I was fine at the time?). I am going to visit both a GI and Neurology specialist, but I would like to ask you if the above tests are sufficient and definitive in ruling out celiac disease. Going gluten-free for a week certainly had an improvement, but I can't be sure If it was a placebo effect or not. Also, if there is possibility of wheat intolerance (never really liked pasta, just the sauce on top), are the above tests any useful at all? Thanks in advance :)

Did you go gluten free before or after tests? The blood tests could be false negatives if you went gluten free before testing. Also, if you want to get more testing (like a biospy) you need to keep eating gluten until the tests are done or the results could be wrong. Even if you keep eating gluten and have the tests and they all turn up negative you may still have gluten intolerance. Unfortunately, the tests are not very sensitive and many get false negatives. If you eat gluten free and your symptoms go away you have found your answer. You alone can decide if you really need a medical diagnosis to stick to the gluten free lifestyle. The only "follow-up" doctor visits a person eating gluten free needs are for other conditions that are common with celiac (thyroid issues, etc.) and to check for extreme vitamin and mineral deficiencies (Low iron, Vitamin D, Vitamin B, Vitamin K, etc). You can get those tests later even if you go gluten free. Also I don't know about Greece, but I know some countries give reimbursements for gluten free food if you have a medical diagnosis of celiac. So you will want to research that and take it in to consideration if it is important to you.

No tests are technically sufficient enough to rule out celiac disease, there are only tests that are capable of ruling in the disease.

I agree. There are many instances of false negatives with blood and biopsy. Even gene tests can't firmly rule it out.

Your body can give you the answer though. If you got relief after just a one week trial it is highly unlikely IMHO that was a placebo effect. After you have had all the testing you choose to do give the diet a good strict try for a couple of months. Then if you still have doubt do a gluten challenge. Start eating it again. If your body needs the gluten-free diet it will tell you in no uncertain terms that it doesn't want gluten by making you sick within a week at the most.

Thank you both for your advice, very helpful :D.

      Headaches / Migraines and Hypoglycaemia

      By trents · Posted

      My migraines generally have their onset during the early morning hours as well. Presently, I am under siege with them, having headaches all but two days so far this month. I have looked at all the things reported to be common triggers (foods, sleep patterns, weather patterns, stress, etc.). Every time I think I start to see a pattern it proves not to pan out in the long run. I'm not sure it's any one thing but may, instead, be a combination of things that coalesce at certain times. It's very frustrating. The medication (sumatriptan or "Imatrix") is effective and is the only thing that will quell the pain. NSAIDs, Tylenol, even hydrocodone doesn't touch it. But they only give you 9 does of sumatriptan a month. And it doesn't help that medical science doesn't really know what causes migraines. They know some things about it but the root cause is still a mystery.

      GI DX celiac despite neg serology and no biopsy

      By Wheatwacked · Posted

      Just a gluten free diet is not enough.  Now you have to identify and replenish your malnutrition.  Celiac disease is co-morbid with malabsorption syndrome.  Low vitamin D, Low Thiamine caused Gastointeston Beriberi, low choline, low iodine are common the general population, and in newly diagnosed Celiacs in the western culture its is more likely.  It takes time to heal and you need to focus on vitamins and minerals.  Gluten free foods are not fortified like regular processed foods.

      Headaches / Migraines and Hypoglycaemia

      By Sarah Grace · Posted

      Dear Kitty Since March I have been following your recommendations regarding vitamins to assist with various issues that I have been experiencing.  To recap, I am aged 68 and was late diagnosed with Celiac about 12 years ago.  I had been experiencing terrible early morning headaches which I had self diagnosed as hypoglycaemia.  I also mentioned that I had issues with insomnia, vertigo and brain fog.   It's now one year since I started on the Benfotiamine 600 mg/day.  I am still experiencing the hypoglycaemia and it's not really possible to say for sure whether the Benfotiamine is helpful.  In March this year, I added B-Complex Thiamine Hydrochloride and Magnesium L-Threonate on a daily basis, and I am now confident to report that the insomnia and vertigo and brain fog have all improved!!  So, very many thanks for your very helpful advice. I am now less confident that the early morning headaches are caused by hypoglycaemia, as even foods with a zero a GI rating (cheese, nuts, etc) can cause really server headaches, which sometimes require migraine medication in order to get rid off.  If you are able to suggest any other treatment I would definitely give it a try, as these headaches are a terrible burden.  Doctors in the UK have very limited knowledge concerning dietary issues, and I do not know how to get reliable advice from them. Best regards,

      @rei.b,  I understand how frustrating starting a new way of eating can be.  I tried all sorts of gluten-free processed foods and just kept feeling worse.  My health didn't improve until I started the low histamine AIP diet.  It makes a big difference.   Gluten fits into opioid receptors in our bodies.  So, removing gluten can cause withdrawal symptoms and reveals the underlying discomfort.  SIBO can cause digestive symptoms.  SIBO can prevent vitamins from being absorbed by the intestines.  Thiamine insufficiency causes Gastrointestinal Beriberi (bloating, abdominal pain, nausea, diarrhea or constipation).  Thiamine is the B vitamin that runs out first because it can only be stored for two weeks.  We need more thiamine when we're sick or under emotional stress.  Gastric Beriberi is under recognised by doctors.  An Erythrocyte Transketolace Activity test is more accurate than a blood test for thiamine deficiency, but the best way to see if you're low in thiamine is to take it and look for health improvement.  Don't take Thiamine Mononitrate because the body can't utilize it well.  Try Benfotiamine.  Thiamine is water soluble, nontoxic and safe even at high doses.  I thought it was crazy, too, but simple vitamins and minerals are important.  The eight B vitamins work together, so a B Complex, Benfotiamine,  magnesium and Vitamin D really helped get my body to start healing, along with the AIP diet.  Once you heal, you add foods back in, so the AIP diet is worth doing for a few months. I do hope you'll consider the AIP diet and Benfotiamine.
