Prometheus Celiac Serology
0

11 posts in this topic

Hi all! I'm new and would appreciate all your thoughts. Gastro dr sent me for cbc, crp and tsh blood tests and I'm to go for prometheus celiac serology test - is this a good, reliable indicator of celiac disease (the nurse warned me of which lab to use because she said lots of them "mess up" the test ?) How long until I get results and can be sure or not if this is my problem? Is there add'l testing after this test? Is heartburn a symptom? I feel like I've swallowed razor blades sometimes. Is swelling/bloating a symptom of celiac (abdomen, ankles, knees)? I look pregnant at times and the aching pain in back, under my ribs, middle and lower abdomen wakes me at night sometimes. This is going to sound weird, but when my abdomen is swollen, I can lay on my back and feel my intestines - hard and swollen, sticking out - it's painful! I think it's gas (which is way more than normal), altho I'm constipated often, taking laxatives (rx'd by dr, but which don't work so well all the time) - that doesn't sound like celiac from what I'm reading. My family does have a history of auto immune disease (diabetes and thyroid), but I personally do not. Can it really be something as seemingly simple as stress or a virus that can trigger this disease? I have been under crazy stress (divorce, raising my kid btn the x and I, other relationship issues, financial stresses.) Some things to consider: I have had eating disorder issues on and off for a long time (15+ yrs - binging, purging, restricting) but have not binged purged in yrs. My diet for the past several years is kind of unusual - mostly veggies, some fruit, no meat, no dairy, some starches. Sounds healthy, however, I love my condiments, vinegar, mustards, dressings and sauces (mostly low and fat free, but not natural, probably just full of preservatives). My weaknesses, in which I indulge often, include pretzels, beer, sugary snacks (like fruit jellies and twizzlers). I have NO energy, at all. My poor kid is suffering because his mom just can't keep up, my body feels old, I feel like I'm 60! All of this is not helping with my lack of a social life, all of which adds up to depression. Does this sound like celiac? Can you tell me about the testing and/or any other things you may know of that this may be (if not celiac?) Thanks so much in advance. I feel like I'm going crazy and any help is so appreciated!

Welcome to the board. You do sound like you could be one of us. Yes celiac does require a trigger and emotional as well as physical stress like an illness or in women childbirth can trigger it.

I can't answer about the particular lab your tests are going to but there is a chance of a false negative with blood screening. Even if tests are negative after all testing is done, including the endoscopsy if your doctors do one as a part of the diagnosis, then go ahead and give the diet a good try.

Thanks for the reply. I've been reading more and see how frustrating this whole process can be so I appreciate your advise. In my reading - holy cow - I can't believe some of the things I've been dealing with that I have assumed were unrelated to my digestive problems could actually be related! Panic attacks, anxiety, fatigue, brain fog - I assumed these were due to not getting enough sleep and stress - and they still very well could be, but I'd not considered the possibility of a link. My diet has become so limited because even the tiniest amount of anything seems to cause me to bloat up and stomach pain. This is odd - I'd run out of a probiotic supplement and B vitamins I was taking and I was nervous that not having these would make me feel even worse. I went about a week without either, and when I began taking them the other day, I started feeling bad again - could that be related - maybe they contain gluten? A few days later, I also indulged in one of my favorites - pretzels and beer, so that could be it too? I'm going for the blood test on Tuesday. I almost can't wait to begin to cut gluten out of my life so I can maybe begin to feel human again. I so appreciate all the information on this website and in this forum!

[snip]I'm to go for prometheus celiac serology test - is this a good, reliable indicator of celiac disease (the nurse warned me of which lab to use because she said lots of them "mess up" the test ?) [snip]

prometheus seems to put a lot of faith in their genetic testing... from their brochure:

Genetic testing detects genes specific to celiac

disease (DQ2/DQ8). The absence of these

genes may allow your physician to rule out

celiac disease for life.

i suppose using the words 'may allow' give them an out; but, the DQ-haplotype analyses are not absolutely predictive.

their serology tests generally includes:

o Anti-gliadin IgG ELISA: <3.5 EU/mL

o Anti-gliadin IgA ELISA: <4.0 EU/mL

o Anti-human tTG IgA ELISA: <3.0EU/mL

o Anti-endomysial(EMA) IgA IFA: Negative

o Total serum IgA: < 3 years: 8-220 mg/dL ; 3-13 years: 41-395 mg/dL ; >13 years: 44-441 mg/dL

i don't think their error rate is any better or worse than any other clinical lab.

It's probably not. Their advantage is that the standard serology tests are the complete panel; many doctors do not order the complete celiac panel. And it doesn't hurt that celiac testing is one of the areas they have 'specialized' in.

I had my genetic testing done through Prometheus, and their results just give you a risk factor, obviously it cannot diagnose. If you come back negative for both of the two genetic markers they are looking for, your results page says that you have a very low chance, but it's not 0%.

My doctor ordered one of Prometheus's other screening panels. I think it included Crohn's, etc. The results indicated a possible Celiac risk. He then performed an endoscopy which positively confirmed it. I think the test was $450. Money well spent IMO. He was the third doctor I tried. The first two knew nothing about nothing.

best regards, lm

I'm replying to this one, but thank all of you for your replies - they are really helping me understand this test and to manage my expectations. So this is not the end, this could be the first of a few more tests to positive celiac or possibly rule it out. And thanks for pointing out the "outs" (may be, less likely, low chance, etc.)

One last thing on the genetic testing. In the US there are only two out of 9 celiac related genes that are tested for. While the majority of celiacs do have DQ2 or DQ8 there are celiacs who carry genes that are recognized in other countries but not here. The genetic tests are one of the tools for diagnosis but they can not for sure tell you that you do or do not have the disorder.

altho I'm constipated often, taking laxatives (rx'd by dr, but which don't work so well all the time) - that doesn't sound like celiac from what I'm reading.

Constipation is common in celiacs. Laxatives don't work for me. I use the diet, juices and magnesium supplements.

Can it really be something as seemingly simple as stress or a virus that can trigger this disease?

My first round of celiacs was just after my divorce. I went undiagnosed. I restricted my eating enough that I "got better" for a couple years. The second round started when my oldest son was jailed and diagnosed with bi-polar disorder.

Some things to consider: I have had eating disorder issues on and off for a long time (15+ yrs - binging, purging, restricting) but have not binged purged in yrs.

Many of us have developed weird eating habits while trying to adapt to our symptoms.

include pretzels, beer

Pretzels and beer would make me really sick. :(

Does this sound like celiac? Could be.

Can you tell me about the testing and/or any other things you may know of that this may be (if not celiac?)

I'm not a fan of the tests. They are expensive and frequently wrong. The only way to know is to go gluten free and see if it helps. .

Could've been the pretzels and beer are what made me feel so crappy the past week, I'm just now feeling better today.

I went for the Prometheus test today and the dr should have results next week. I'll keep what y'all said in mind when I do get the results.

I did get my other results in, from the lab so they've not been read by the dr yet. It says my rbc is low (hmoglobin and hematocrit low) but mcv and mch are high. Everything else is in the normal range. So I think this means I'm anemic, which would explain why I am so weak and fatigued. Not sure if or how this relates to celiac - looks like I have some reading to do. Thanks again, really, you guys are so helpful!

So the dr didn't have results as of Friday. How long do the results usually take? With all the reading I decided to try to watch for any reactions. I have cut a lot out of my diet, basically been eating fruit and lettuces and stopped vitamins, supplements, laxatives and I felt so much better. End of this week I made a broccli and spinach dish (basically, just some canola oil, balsamic vinegar, pepper and garlic) and my stomach began to swell this moring. I had apples, lettuce and more broccli dish during the day and began to feel worse, in a lot of pain. Now I'm wondering if maybe it's the balsamic vinegar? What else could it be? The only thing I've done different if eat the broccli dish.

    • Did your doctor check for SIBO, H. pylori, ulcers, etc. when he was obtaining biopsies to check for celiac disease?  
    • Oh, and as I mentioned in my own post on pain, xanax. I swear. I tried it just to deal with the occasional panic I had at weird scary symptoms and clueless doctors. I am not a fan of long term use. But I recently found that .25 mg seems to aid with the neuropathic pain. It does not go away, but it helps. 
    • It does sound like a Glutening and you are just a few months into the diet.  It might help if you read our Newbie 101 thread under the "Coping" section.   Here is some information about rice milk: https://www.verywell.com/is-rice-dream-gluten-free-562354 Many, many celiacs are often lactose intolerant temorarily or permanently if you are naturally genetically inclined.  When I am glutened, I lose the ability to digest lactose for a while.   Salad?  Great but it can be rough on a sore gut!  Think soups, stews, easy-to-digest foods that you prepare yourself until you feel better.  Did your folks give you salad after a bout of flu?  Or did you stick with jello and broth?  I am intolerant still after three years to garlic and onions (the lactose resolved, thankfully).  You have a leaky gut (Google zonulin and Dr. Fasano who is a leading celiac researcher to verify that this is true) and that means you can become intolerant to anything (hopefully, just temporarily).   If you are 100% sure that you have had no access to gluten....did you eat out lately?.....then see your doctor.  Remember, celiac disease symptoms can change.  And here is the biggie.....it can take weeks, months or years to heal from celiac disease.  Two months in is nothing, really.  Why?  It takes time to figure out the diet and time for antibodies to come down.  celiac disease is an autoimmune disorder triggerEd by gluten.  once triggered it can go on and on damaging your gut especially with repeated glutenings (accidental or through cross contamination). I hope you feel better soon!  
    • I concur! I literally feel your pain as well. Like, at the moment, lol. Did you have an endo to see inflammation or damage? I am close to begging my GI for carafate or something to coat and protect. How about testing your antibodies to see if they are still rising? I read somewhere here rice milk may not be a good option.  Folks here have also suggested to me to stick with whole foods. Limit processed. Especially stuff that is not certified gluten-free, like chex. I think small amounts of gluten are in processed foids and can add up. I too reacted to lettuce the other day like I was ingesting glass. My sibling  had a food sensitivity panel done and it came back positive for a few things he had been eating a lot of. He can now eat them, but had to cut them out of his diet. Lettuce is probably on mine.  I have been drinking carrot and pomegranate juice,  dandelion root tea with hiney, aloe water, lots of squash, fish. Mild, no garlic, no onions or hot sauce. No coffee. It sucks.  Inflammation can tick off other organs, you mention a "Pain below". Not exactly sure which side, but certainly call your doc Monday. Sooner if the pain increases.
    • You should see a GI specialist before you go gluten free.  They should do a upper endoscopy to check for celiac damage.  Colonoscopy won't show anything related to celiac.  Also no you should not feel worse on gluten free, you should feel better.
