Biocard Celiac Test - Is It Accurate?

Hi,

I have just done the Biocard test and it resulted 'negative'. Can this be reliable?

I have long been suffering from GI problems and was diagnosed with IBS about 9 years ago. Since around 2007 I have also been diagnosed with sinusitis and asthma, for which I receive inhalers and steroid spray. I have also been diagnosed with iron deficiency anaemia and have been taking Ferrous Sulphate tablets for about 3 years (as level seems to be stable with them). I have had a rash on my back and abdomen for years. It is not like the pictures of DH that I have seen on the net nevertheless it is a permanent eczma, which is very itchy. I also suffer from dry eyes and mouth though I tested negative to rheumatoid arthritis blood tests this summer (but had higher than the indicated range of aspartate tranferase?).

As the above seem to be consistent with gluten intolerance and coeliac I decided to exclude gluten and started to feel better after a few days (though had a few accidents since). I was off gluten for at least 4 consecutive days last week, had an accident last Saturday (severe reaction including stubbing, open wound pains in my bowel) and again on Tuesday. I decided to eact gluten bread yesterday evening and this morning. I did the test this lunchtime.

Is it possible that the test result may not be accurate (I got the control line appear)? Is it still possible that I may be coeliac but either the test was faulty or the recent reduction in gluten intake caused it?

I look forward to hearing your opinion!

If you suspect gluten is the cause of your concerns. I suggest a full Serologic Celiac Panel. This is what you doctor should order:

Anti-gliadin antibodies (AGA) both IgA and IgG

Anti-endomysial antibodies (EMA) - IgA

Anti-tissue transglutaminase antibodies (tTG) - IgA

Total IgA level.

Biocard has its limitations. If you are IgA deficient, then a negative result on the Biocard test would be inconclusive. Best to have the full celiac panel run by a lab.

About your rash. sounds like DH, because of your other symptoms, and because it is itchy.

If you can get it biopsied during an outbreak, then you are celiac too, officially.

DH is caused by the ttg3 antibody, as opposed to ttg2 in celiac.

The ttg-test does not pick up ttg3, only ttg2.

Gluten ataxia is caused by ttg6, and I have not seen tests for that either.

The biopsy must be taken from halthy skin, as the IgA is used up in the lesions, and during an outbreak.

DH result as a response to gluten intake and develops on the skin . Celiac Disease results as an autoimmune response in the small intestines. They have many common denominators, but yet are different.

Hi Lisa,

I am so glad that I have found your post. I have spent countless hours trying to find the best test for gluten intolerance/sensitivity but they seem to be not very accurate.

Would you say that the full Serologic Celiac Panel is my best bet? If the results come back normal then does it mean that I am 100% OK or still there could be some issues that the test did not detect? Are there any other tests that I should take to get sure 100% that I do not have any gluten issues or full Serologic Celiac Panel is all that I need?

BTW is gluten intolerance and gluten sensitivity the same thing?

Thank you very much in advance.

Hi Lisa,

I did look at the link and the articles but I do not see any definitive, straightforward info there.

Does the fact that you directed me somewhere else mean that the full Serologic Celiac Panel is not a comprehensive test? What is the best test(s) then?

Also I am still confused if gluten intolerance, gluten sensitivity and celiac are the same thing and if the same test(s) are used for all of them.

I appreciate your help in that regard.

Thank you.

Alina

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      Clearly from what you've said the info on Dailymed is much more up to date than the other site, which hasn't been updated since 2017. The fact that some companies might be repackaging drugs does not mean the info on the ingredients is not correct.

      Waiting Gastroenterology review

      To evaluate the TTG antibody result we’d need to know the normal range for that lab.  Labs don’t all use the same units.  However, based on any normal ranges that I’ve seen and the listed result being greater than a number rather than a specific number, I’d say yes, that is high! Higher than the range where the test can give a quantitative result. You got good advice not to change your diet yet.  If you went gluten free your intestines would start to heal, confusing any further testing,

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Bev in Milw · Posted

      Scott is correct….Thank you for catching that!      Direct link for info  of fillers.    http://www.glutenfreedrugs.com/Excipients.htm Link is on 2nd page  of www.glutenfreedrugs.com   Site was started by a pharmacist (or 2) maybe 15-20 yrs ago with LAST updated in  2017.  This makes it’s Drug List so old that it’s no longer relevant. Companies & contacts, along with suppliers &  sources would need to be referenced, same amount effort  as starting with current data on DailyMed      That being said, Excipient List is still be relevant since major changes to product labeling occurred prior ’17.           List is the dictionary that sources the ‘foreign-to-us’ terms used on pharmaceutical labels, terms we need to rule out gluten.    Note on DailyMed INFO— When you look for a specific drug on DailyMed, notice that nearly all of companies (brands/labels) are flagged as a ‘Repackager’… This would seem to suggest the actual ‘pills’ are being mass produced by a limited number of wholesaler suppliers (esp for older meds out of  patent protection.).      If so, multiple repackager-get  bulk shipments  from same supplier will all  be selling identical meds —same formula/fillers. Others repackager-could be switching suppliers  frequently based on cost, or runs both gluten-free & non- items on same lines.  No way to know  without contacting company.     While some I know have  searched pharmacies chasing a specific brand, long-term  solution is to find (or teach) pharmacy staff who’s willing help.    When I got 1st Rx ~8 years ago, I went to Walgreens & said I needed gluten-free.  Walked  out when pharmacist said  ‘How am I supposed  to know…’  (ar least he as honest… ). Walmart pharmacists down the block were ‘No problem!’—Once, they wouldn’t release my Rx, still waiting on gluten-free status from a new supplier. Re: Timeliness of DailyMed info?   A serendipitous conversation with cousin in Mi was unexpectedly reassuring.  She works in office of Perrigo, major products of OTC meds (was 1st to add gluten-free labels).  I TOTALLY lucked out when I asked about her job: “TODAY I trained a new full-time employee to make entries to Daily Med.’  Task had grown to hours a day, time she needed for tasks that couldn’t be delegated….We can only hope majorities of companies are as  conscientious!   For the Newbies…. SOLE  purpose of  fillers (possible gluten) in meds is to  hold the active ingredients together in a doseable form.  Drugs  given by injection or as IV are always gluten-free!  (Sometimes drs can do antibiotics w/ one-time injection rather than 7-10 days of  pills .) Liquid meds (typically for kids)—still read labels, but  could be an a simpler option for some products…

      Food Allergies

      By Ginger38 · Posted

      So I recently had allergy testing for IGE antibodies in response to foods. My test results came back positive to corn, white potatoes, egg whites. Tomatoes, almonds and peanuts to name a few.  I have had obvious reactions to a few of these - particularly tomatoes and corn- both GI issues. I don’t really understand all this allergy versus celiac stuff. If the food allergies are mild do I have to avoid these foods entirely? I don’t know what I will eat if I can’t  have corn based gluten free products

      7yo struggling!

      By JForman · Posted

      We have four children (7-14 yo), and our 7 year old was diagnosed with NCGS (though all Celiac labs were positive, her scope at 4 years old was negative so docs in the US won't call it celiac). We have started her on a Gluten Free diet after 3 years of major digestive issues and ruling out just about everything under the sun. Our home and kitchen and myself are all gluten-free. But I have not asked my husband/her dad or her other siblings to go completely gluten-free with us. They are at home, but not out of the home. This has led to situations when we are eating out where she has to consistently see others eating things she can't have and she has begun to say "Well, I can't have <fill in the blank>...stupid gluten."  How have you supported your gluten-free kiddos in the mental health space of this journey, especially young ones like her. I know it's hard for me as an adult sometimes to miss out, so I can't imagine being 7 and dealing with it! Any tips or ideas to help with this?
