Is It Possible To Bypass The Blood Tests In Favor Of Immediate Endoscopy?

Hi everyone. I'm "officially" new here, though I've been haunting for a good while. 

 

Like SO very many of you lovely, helpful people, I've been sick in weird ways for as long as I can remember. After a very long journey into innumerable aspects of nutrition and holistic health, I finally realized that gluten is/has been the source of my sickness, and upon this realization, I immediately cut it out of my diet. That was almost 11 months ago. I've followed a strict gluten free diet since then, with the exception of cross contamination, which I didn't really take seriously until recently. 

 

When I first cut gluten out, I thought that I must just be sensitive. The possibility of celiac never occurred to me, though I was familiar with the disease at the time. But as time has gone on, I've thought more and more about my health history, it has become apparent to me that I've had MANY celiac symptoms through the years, and that these symptoms cleared up once on a gluten free diet. 

 

I would happily live the rest of my life without gluten, and I quite honestly don't want to be ANYWHERE near the stuff. I was delighted when I figured out that gluten makes me ill, and each time I turn it down, it makes me feel GOOD knowing that I'm turning down the substance that made me feel sick for so long. BUT (ha!) the big but...

 

I would like to pursue a diagnosis for a couple of reasons. The first is family: if I do indeed show evidence of celiac disease and can get a positive diagnosis, this might be the leverage needed to encourage my family to get tested. They are not the sort of people who think about nutrition or the source of their illnesses. They're more of the "give me a pill and send me on my way, doctor" types. But if I have a fancy, shiny diagnosis, I think they might get tested, and I KNOW that removing gluten from their diets (particularly my mom's) would be life changing for them. I suspect that the majority of my mother's strange healthy issues could be related to celiac disease. 

 

The second reason is because of the obvious lifestyle changes that one must implement. I'm already quite strict, as I said, but I haven't really enforced CC issues when eating with my family or in restaurants. I know it seems silly, because I DO value my health above all else, but if I'm going to be incredibly particular about cross contamination issues, I feel that I need to have a more valid reason than "I just feel better not eating it." It's a big thing to ask your family to completely change everything about the way they prep food just because you're coming over for lunch. It's a big thing to ask a restaurant to be so incredibly particular with your food prep if you don't have a completely legitimate (I guess in my mind that's an official diagnosis) reason for such a request. 

 

Anyway, the main question that I wanted to ask is this: If, after being on a gluten free diet for nearly a year, it will take months of suffering to MAYBE get a positive blood test, (and like I said, I absolutely DREAD being back on gluten,) would it not make more sense, given my history of symptoms, to just go straight for an endoscopy to check for damage after just a few weeks of ingesting gluten?

 

Or is it the case that doctors are generally unwilling to do the procedure without first having a positive CBP? 

 

Thanks so much for reading/listening to me share experiences/any advice you may have.

Ask the GI. Take this in for him/ her to see.

What is a gluten challenge?

A gluten challenge is the period of time when gluten is added back into a person’s diet to assist in the diagnosis of celiac disease. Antibodies take time to build into the blood stream before they can be detected through blood analysis. For a gluten challenge we recommend eating 1/2 slice of bread or a cracker each day for the duration of the challenge.

Prior to blood testing we recommend 12 weeks of eating gluten.

Prior to an endoscopic biopsy we recommend 2 weeks of eating gluten.

In the case of a severe reaction to gluten, a medical professional may opt to shorten the 12-week challenge and move immediately to an endoscopic biopsy.

      Exactly! Negative genetics can rule out celiac disease with close to 100% certainty. It takes tTg antibody testing and biopsy confirm the diagnosis in a genetically susceptible individual.

      What Dr. Gunn states is essentially true. It is a rule out measure. But be aware that to possess either of the two primary genes that have been identified with celiac disease (or both) doesn't necessarily mean that you have or will develop celiac disease. Almost 40% of the general population carries one or both but only about 1% of the general population will develop active celiac disease. It remains latent until triggered by some stress event which may or may not occur. So, there is a genetic component to celiac disease but there is also an epigenetic component. 
    • Dr. Gunn
      Have you had celiac genetic risk testing? A celiac genetic test is accurate with or without gluten in your diet. If you don't carry the celiac risk genes you can effectively rule out celiac disease for life.

      Based on those results alone, it’s not possible to say you have celiac disease. The test that is usually most specific for celiac, tTG-IgA, is negative in your results, and the endomysial antibody (EMA) is also negative, which generally argues against active celiac disease. However, your deamidated gliadin IgA is elevated, and your total IgA level is also high, which can sometimes affect how the other antibody tests behave. Another important factor is that you were reducing gluten before the test, which can lower antibody levels and make the results less reliable. Because of that, many doctors recommend a gluten challenge (eating gluten regularly for several weeks) before repeating blood tests or considering an endoscopy if symptoms and labs raise concern. It would be best to review these results with a gastroenterologist, who can interpret them in context and decide whether further testing is needed.

      Since you compromised the validity of the antibody testing by experimenting with gluten withdrawal ahead of the testing, you are faced with two options: 1. Reintroduce significant amounts of gluten into your diet for a period of weeks, i.e., undertake a "gluten challenge". The most recent guidelines are the daily consumption of at least 10g of gluten (about the amount found in 4-6 slices of wheat-based bread) for at least two weeks leading up to the day of testing. Note: I would certainly give it more than two weeks to be sure. 2. Be willing to live with the ambiguity of not knowing whether gluten causes you problems because you have celiac disease or NCGS (Non Celiac Gluten Sensitivity). There is no test for NCGS. Celiac disease must first be ruled out and we have tests for it. Celiac disease has an autoimmune base. NCGS does not. GI symptoms overlap. In the early stages of celiac disease, other body systems may not be showing stress or damage so, symptomatically, it would be difficult to distinguish between celiac disease and NCGS. Both conditions require elimination of gluten from the diet for symptom relief. Some experts feel that NCGS can be a precursor to celiac disease.
