New Insights into Inflammatory Bowel Disease Serology Testing

Celiac.com 06/19/2009 - Specialty pharmaceutical and diagnostic company, Prometheus Laboratories Inc., announced results from two recent studies concerning the use of serologic testing to predict inflammatory bowel disease (IBD).

The first study assessed the consistency of biomarkers in patients who received multiple Prometheus IBD Serology 7 tests within a two-year period. Overall levels for repeat testing orders were just 2.2%.  Original and repeat tests showed a high degree of agreement. Average variation in biomarker serum concentrations ran between 2.2 EU/mL and 4.3 EU/mL.

Results agreed with prior studies suggesting biomarker stability over similar time periods. Further studies are needed to gauge the impact of therapy on biomarker stability over the long term.

A second, multi-center clinical study of 1,574 subject samples brought the total development cohort of the test to a more heterogeneous 3,626 patient samples.

Results with this large patient cohort further showed that combining multiple markers with Prometheus' Smart Diagnostic Algorithm permits clinicians to better distinguish IBD vs. non-IBD and Crohn's disease vs. ulcerative colitis, compared to standard cutoff value analysis of the individual markers alone.

Prometheus IBD Serology 7 combines multiple serologic markers with a proprietary Smart Diagnostic Algorithm, increasing test sensitivity by more than 25% over single marker sensitivity values.

That's good to know about Texas Children's, unfortunately I don't believe they accept our insurance. Our former pediatrician joined with one of their medical groups and we had to find a new one due to insurance. I'll check out their site though.

Texas children's hospital in the med center has a celiac center now. https://www.texaschildrens.org/departments/celiac-disease-clinic Good luck!

this is a very common subject on here. personally, most of my tests were negative, but i did the same thing you did (stopped eating gluten before the tests) my gi advised me to continue eating gluten free because i was so malnourished and when i stopped the gluten i actually began to gain weight. in other words, i think she was afraid for me to do the challenge bc it might kill me lolz. some people want a definite dx if they have kids that need to be tested in the future, some will not follow a strict g//f diet without a firm diagnosis (they think they can cheat just bc they were never formally diagnosed) what happened with my scope is the dr saw evidence of damage. that and my response to the diet were enough for me. she advised me to stay gluten-free and i agreed. it's been tough sometimes, but i never purposely cheated (that's how near death i was - swore i was dying of the big 'c'.......what a relief to not have that and my 'chemo' is 'impasta'. or fake bread. ) welcome to the forum and good luck with whatever you choose

I'm already noticing a difference after five days on the gluten-free diet...acid reflux is gone and stomach pain is getting better. I am glad you're going to try the gluten-free diet, Vanillabean, and get copies of all your results. I hope you find some relief from the pain soon! I'm still waiting for my biopsy results. I did call my doctor's office today and found out the genetic test was positive for a celiac gene (DQ8). My doctor was hoping to rule out celiac with that test, but now it's still up in the air. Still waiting.

meeeeeee!!!! i used to get pneumonia every single winter!!!! and all the flus and colds, etc - i am surrounded by kids and germs, but when they all get the flu, i do not. my husband (mr-play-through-the-pain) even got knocked down (spent 2-3 days in BED miserable) by the last round of virus, but not me. not to mention no headaches, no migraines, etc. hormones and the dreaded menopause, like hellodee2 said, is a whole 'nother ballgame lolz glad you are feeling better
