Just curious about the accuracy of the Prometheus lab tests for IBD. I am taking a poll.

I was diagnosed with Crohn's in 2006 based on a colonoscopy (and biopsies). A colonoscopy (and biopsies) this September showed no signs of disease activity, so my GI ordered a Prometheus test. The results of the test showed patterns consistent with UC.
This really says nothing about the accuracy of the Prometheus test, however, as I still have no idea which (if any) diagnosis I have received is correct.

The blood test results always look great. I recently had a colonoscopy and MRI, that showed active inflammation. W-T-F.

I hope the pill test goes well for you. Do you have to take the same prep for that as for the colonoscopy? Keep us posted Dar. So did they think the inflammation was UC? I have my apt next week.

I'm the opposite. My blood tests were off the chart positive for crohns. My colonoscopy showed mild inflamation and nothing in the biopsies. I was diagnosed by symptoms and blood test. My blood test showed "severe" crohns, symptoms were moderate, colonoscopy showed mild if anything.

FitzyK, do you remember your numbers? My ASCA was 1:120. It was three times the cut off. My sed rate and crp have been high for years and nobody knew why....

I don't. I have my records somewhere. I just moved and wouldn't even know where to look. I know it gave the number and then to the right gave a percent. Mine was 320% on the field about crohns. I'm also lactose intollerant too which I hear can make your numbers higher.

Yea, I am lactose intolerant too. I didn't get a percentage, just the titer. I have an apt Wednesday and can't wait to hear what they have to say about the test. I sure hope they switch my meds to something that will work. Colazal is not working. I just hope they don't want to scope me again-:) Be well-:)

Try another serology solution, IBDX, manufactured by Glycominds, uses 4 markers, including a form of ASCA, that are glycan-based markers. Ask your doctor to order this serology test. It can be run at Labcorp or ARUP laboratories. It is a much better serology solution.

My docs say they don't use the lab tests much for adults. I guess because they feel it is ok to poke and prod us at will. Ha! I am having a repeat sigmoidoscopy in 3 weeks and a ct scan on monday, so I should have some more answers. The colazal is not keeping it under control. they did admit these diseases can evolve and change. I don't think they are ready to use the lab tests to diagnose me with crohn's yet but obviously with the test and my symptoms they want to look and biopsy.

You should ask for it. Some docs are reticent to use serology, but the tide is changing with top down therapies and markers that can assist in determining recurrent severe symptoms (prognostic testing). The nice part about the IBDX solution is that it is fully covered/reimbursable, using simple cpt codes. I wish you luck and don't let them prod, poke and cut you if you get answers using much less invasive means.

Mine came back negative for Crohn's and UC. However, all my other bloodwork points to active inflammation and Crohn's. Biopsies have been postive for focal active colitis. Right now I'm diagnosed as unspecified IBD.

Wow, at least they put you on some strong meds. I've had a year of misery and all they put me on was colazal and some rectal meds that I hate. So, now they want more tests after my serology was positive.

Mine was unsure - they don't know if it's Crohn's or Colitis. The Prometheus tests were ordered by my dr to help determine which, and he also said my insurance would cover them. Neither of those worked out for me, I had no new information and had to pay like $550. If I had the chance, however, to find out exactly what I had and to better treat it I probably would get it done. It's a big disappointment and expense when they tell you they just don't know though.

Sorry it didn't solve any problems for you. Yes, you are right, it is upsetting when when you are out so much money and still no answers. My medical bills this year were outrageous and I don't have a lot of answers yet either. Did you keep trying to get your insurance to pay for the tests and appeal the decision? Sometimes it is just too much of a hassle, so you just pay. I didn't even have that much done and my medical bills this year were almost 10k and that is my out of pocket cost. It was so much that I am almost at the point where my insurance picks up 100%. I might actually reach it with this next CT Scan, but it is too late in the year to help. Next year, we are changing to another insurance where our out of pocket won't be so much.
