I was dxed with UC back in May '06, reaffirmed by c-scope in January '07. I had a prmoetheus blood test done while I was in the midst of a full on flare in July...it came back as negative for either Crohn's or UC. A month later I had a c-scope done, and I had inflammation and scarring as well as pseudo-polyps in 70cm of my intestine..and proved once again that I really did have UC.
The prometheus test is not infallible, and only has an 80% accuracy rate. There are several members on the board who have had the test done and it came back negative despote a bundle of evidence to the contrary. One other member that I can think of, Emory, had been dxed via c-scope as UC, but the prometheus test showed negative for IBD.
Another drawback to the prometheus is that it usually not covered by insurance, which makes it a very expensive test to give a flase diagnosis (at least for me and others). The blood test for crohn's/UC wound up costing me $345 out of pocket, no insurance help.
The gold standard for diagnosing Crohn's and UC is through c-scope and biopsies. For sure, the blood test is less invasive, so go ahead and get it done. Just don't take the results as the gospel. If it comes back negative, do the old standard: c-scope, which will do a much better of giving you a concrete dx.
Good luck. I hope the prometheus test works for you, and I also hope for your sake that you only have UC. Crohn's, while similar to UC, has it's own challenges, and those with Crohn's tend to have more complications, and a harder time gaining remission. Hopefully this won't be the case for you.
Everyone who has gotten the test done, please keep us posted on what you test results came back as. I would love to be able to recommend the prometheus over c-scopes, but at this point, I can only let people know the failings of the prometheus. It would be great to say that the prometheus is very reliable. Please give me the info I need to sway my opinion.
