Confusing symptoms

I’ve only just had a diagnosis of coeliac from a blood test and I am awaiting a referral for a biopsy presumably to ascertain the level of damage to my intestine. I don’t seem to have the usual symptoms which I have read about on this site. I’ve never had diarrhoea, but I’ve had constipation on and off for the last three years. Unfortunately, as I’ve had MS for 25 years and a faulty hip replacement, I take a low level painkillers and osteoporosis medication both of which can cause constipation so it never occurred to me I had coeliac. Especially as I don’t seem to have any of the other symptoms that people describe here although I do have dry eyes and I was amazed to read that that can be a symptom of coeliac. I’m seeing a doctor on Monday and I will ask for a copy of my blood test results.  Could somebody tell me what questions I should ask the doctor about my blood test results and what I should look for in the biopsy result as a lot of it is very confusing. Apparently my blood test was 8.9.  Is that an antibody score?  I know they call it a weak positive but only just. Hoping that that score is reasonably good news or is it meaningless without the biopsy?

Can you also provide the reference range that should be with your test result?

We've done some research summaries on MS and celiac disease that you may find interesting:
https://www.celiac.com/celiac-disease/celiac-disease-amp-related-diseases-and-disorders/multiple-sclerosis-and-celiac-disease/

This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.

Our wonderful NHS has become rather slow of late so I am still waiting to find out more about my test results. I have recently had more blood tests taken which seem to be for vitamin deficiencies and I have my endoscopy next Wednesday. I will definitely ask what scale is used and then I will post my results. I am very grateful for the advice I have been given on this site.

I hope you have been eating gluten daily, lots of it, for your endoscopy. Some people mistakenly go gluten-free before all testing for celiac disease is completed, and doing that can cause false-negative results.

I have been making sure my gluten intake is as high as possible eating loads of bread and pasta. The strange thing is, it’s not making me feel ill at all.  It never has. And yet I definitely tested positive positive for coeliac on my antibody test. Very strange.

Many people with celiac disease are asymptomatic, but unfortunately if they keep eating gluten they still run the same health risks as those who have symptoms.

      I had to rush to the hospital last week due to anaphylactic shock from taking a dose of an antibiotic. Received EpiPen, steroids, antihistamines, zofran (all injected/IV). When I woke up the next day, ALL of the rashes I've had that started since going gluten free were cleared up. EVEN THE dermatitis herpetiformis was gone. Has anyone else experienced this or happen to know why that would happen? The meds they gave me were all meds that I've taken to try to resolve the rashes, but they never worked in pill form. I'm wondering if it the addition of the epi that helped, it if injected steroids and antihistamines were what did the job.

      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. 
    • Scott Adams
      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.
