Measles Antibodies

A number of years ago I worked for a few months in our hospital pharmacy. I had to show proof of measles vaccination. I had never been vaccinated for measles because when the vaccine came out and the rest of my family had their shots, I was recovering from chicken pox. Even though I felt fine the dr felt I should wait another week as this was a live vaccine. The next week was spring break and we drove Missouri where my dad was on a job. By the second day, I had the measles. I was very sick.

Anyway, I explained this to the hospital and they drew blood and said they were checking my antibodies to verify my illness. The test came back positive and that was that.

Now I'm wondering how they know what antibodies show measles. Does anyone know that? I tried to look it up but had no luck. How do they know what are measles and could have been celiac disease? I haven't had any tests for celiac disease and have gluten-free for more than a year. I started to wonder if that old test could show I had celiac disease way back when...is this possible?

They look for the measles antibody in your serum. They do this by screening for antibodies using the measles antigen, such as measles protein. The measles antigen is usually immobilized on a surface, such as a plate or well. Then your serum is added and any measles antibody you might have in your serum will bind to the measles antigen on the plate. Then the plate is washed and another conjugated antibody is added that binds to your antibody This second antibody is capable of fluorescing or producing a color change which is measured. This indicates a positive result. They can also perform this test on dilutions of your serum to achieve a quantitative result. There are variations on the testing methods, but this is a common and basic method. I hope this helps. Basically it is a specific reaction between a measles component and your measles antibody.

Thanks for the answer. I really never knew how that worked. I wondered if there was that test out there that might have shown the beginnings of celiac disease way back then. It doesn't sound like it.

      Draft gluten-free ciders… can they be trusted ?

      By Rejoicephd · Posted

      That and my nutritionist also said that drinking cider is one of the worst drink choices for me, given that I have candida overgrowth.  She said the combination of the alcohol and sugar would be very likely to worsen my candida problem.  She suggested that if I drink, I go for clear vodka, either neat or with a splash of cranberry.   So in summary, I am giving ciders a rest.  Whether it's a gluten risk or sugars and yeast overgrowth, its just not worth it.

      Tea Bags and Gluten

      By Scott Adams · Posted

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      Inconclusive results

      By Scott Adams · Posted

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. 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.

      Medication

      By Scott Adams · Posted

      Welcome to the community! Generally, for a gluten challenge before celiac disease blood tests, Tylenol (acetaminophen) is considered safe and should not interfere with your antibody results. The medications you typically need to avoid are those like ibuprofen (Advil, Motrin) or naproxen (Aleve) that can cause intestinal irritation, which could potentially complicate the interpretation of an endoscopy if you were to have one. However, it is absolutely crucial that you confirm this with either your gastroenterologist or your surgeon before your procedure. They know the specifics of your case and can give you the definitive green light, ensuring your surgery is comfortable and your celiac testing remains accurate. Best of luck with your surgery tomorrow
