My son was diagnosed with Celiac a few months ago (both bloodwork and biopsy positive). I have have bowel issues all of my life and the symptoms seemed to have gotten much worse after the birth of my daughter 9 months ago. I thought I had found my answer and was fully expecting a positive dx. I had bloodwork done and everything came back negative. My TTG antibody was <3 (<5 negative, 5-8 equivocal, >8 positve reference range) and my IGA Serum is 179 (81-463 reference range). Can anyone tell me more about my results? I am not sure if I should drop it or pursue more tests. Thank you for your help!

Welcome to the forum!!

Have you tried the gluten free diet? The number of people on here with negative bloodwork but either a diagnosis or positive results is pretty high. My bloodwork was negative, but I have Celiac.

It really is up to you at this point if you want to pursue it. If you try the diet, you skew your chances of an accurate result. But if you decide to pursue it, don't quit eating gluten for any length of time.

Are those two tests the only ones they did?

The blood tests, especially ttg and EMA are really calibrated to be positive only in th most severe cases and are negative in 20% even then.

I would pursue more testing. You were only tested for one antibody (tTG). Also, some people will have a positive biopsy despite negative bloodwork. I would request the Celiac panel.

The IgA Serum is to make sure that you're not IgA deficient.

As previously mentioned you could try the diet to find out if gluten is your problem....just be sure that you do not wish to pursue testing before you start the diet.

Genetic testing could also be useful as your son may have gotten his Celiac gene from his father.

After my son was dx I stocked the kitchen with gluten-free food and that's what I was eating too, it was just easier for all of us to eat the same things. I did have some gluten each day, but for the most part I was gluten-free. I am afraid my gluten-free diet for those 10 weeks resulted in negative tests. Is that possible? I was not aware that cutting gluten before testing could result in negative tests until I started really reading posts from this website and others. By then it was too late. My family dr has referred me to a GI. I will talk to him about the pros and cons of more testing. Thank you for your help! I truly appreciate it.

Yes...you would have to be eating gluten in order for the tests to be accurate. If you take gluten out of your diet antibody levels go down. 10 weeks gluten-free can definately result in a false negative.

      Bitters for digestion?

      This sounds to me like histamine intolerance. Some foods have more or less histamine. processed or aged meats, fermented food like yoghurt or kimchi and bread (yeast), spinach, eggplant and mushroom are high in histamine. Other foods like tomatoes are histamine liberators, they encourage your mast cells to release histamine, which can also trigger the reactions...

      Why Bananas No Longer Cure Celiac Disease

      I missed this article when it was first put up. It is interesting to read, as my old neighbour who sadly passed away a few years ago was a trainee midwife during WWII. Bananas disappeared from the shops in Britain during the war, but she told me that those that did get to the UK were kept back for infants with coeliac disease. I didn't realise that...

      @GeoPeanut, milk is one of the better sources of iodine. Iodine is known to exacerbate dermatitis herpetiformis. Many people find that a low iodine diet helps them avoid dermatitis herpetiformis outbreaks. So, maybe the fact that you have limited your dairy intake of late is helping with that.

      Celiac or Addison's complications? Can someone share their experience?

      This sounds to me like histamine intolerance. Some foods have more or less histamine. processed or aged meats, fermented food like yoghurt or kimchi and bread (yeast), spinach, eggplant and mushroom are high in histamine. Other foods like tomatoes are histamine liberators, they encourage your mast cells to release histamine, which can also trigger the reactions you describe, flu like symptoms, joint pain, urinary tract irritation, rash, stomach upset, nausea, diarrhoea & fatigue. I had liver pain like you describe, as part of the intolerance is usually a sluggish liver that makes processing all the histamine difficult. There are multiple possible root causes of histamine intolerance, usually it’s a symptom of something else. In my case, leaky gut (damaged gut wall)caused by undiagnosed celiac, but for others it’s leaky gut caused by other things like dysbiosis. Some people also experience histamine intolerance due to mould exposure or low levels of DAO (the enzyme that breaks down histamine in the gut). I’d try a low histamine diet & if that doesn’t improve symptoms fully, try low oxalate too. As others have suggested, supplements like vitamin d, b, l-glutamine to support a healthy gut & a good liver support supplement too. If you’re in a histamine flare take vitamin c to bowel tolerance & your symptoms will calm down (avoid if you find you have oxalate intolerance though). Best of luck

      Welcome to the forum, @KRipple! Sorry to hear of all your husband's health problems. I can only imagine how anxious this makes you as when our spouse suffers we hurt right along with them. Can you post the results from the Celiac blood testing for us to look at? We would need the names of the tests run, the numeric results and (this is important) the reference ranges for each test used to establish high/low/negative/positive. Different labs use different rating scales so this is why I ask for this. There aren't industry standards. Has your husband seen any improvement from eliminating gluten from his diet? If your husband had any positive results from his celiac blood antibody testing, this is likely what triggered the consult with a  GI doc for an endoscopy. During the endoscopy, the GI doc will likely biopsy the lining of the small bowel lining to check for the damage caused by celiac disease. This would be for confirmation of the results of the blood tests and is considered the gold standard of celiac disease diagnosis. But here is some difficult information I have for you. If your husband has been gluten free already for months leading up to the endoscopy/biopsy, it will likely invalidate the biopsy and result in a false negative. Starting the gluten free diet now will allow the lining of the small bowel to begin healing and if enough healing takes place before the biopsy happens, there will be no damage to see. How far out is the endoscopy scheduled for? There still may be time for your husband to go back on gluten, what we call a "gluten challenge" to ensure valid test results.

      Are they close to a drug that will help celiacs with cross contamination

      By kate g · Posted

      Ive read articles that there is stage 2 research being conducted for drugs that will limit damage to celiacs through cross contamination- how close are they to this will there be enough funding to create a mainstream drug?
