I understand there is a blood test to test for UC?  How accurate is it?  My 17 yr old worries she may have it since I do.  But should we bother finding out?  She has no symptoms.  So finding out may just be depressing.  Would there be a benefit to knowing??

I believe you're thinking of the Promethius test, which is expensive and probably wouldn't be covered by insurance. It's usually used to differentiate between UC and Crohn's. The reliability isn't very good, in fact a lot of GI's never use it as part of their diagnosis.

The only suggestion I can make is for your daughter to eat a colon-healthy diet with plenty of fiber and fluids. She also could be taking probiotics daily to help maintain healthy intestinal bacteria.

If your daughter has no symptoms, I wouldn't get tested. She shouldn't live in fear of getting it. It can be genetic but not always. No one in my family has UC, I'm one of 22 cousins and I'm the only lucky one with UC..lol. I'm not sure if a test can say that you have UC if you're not having symptoms anyway and even if it can, what is she going to do about it? You can't prevent the disease from happening.

I took the Prometheus test; I think it was $500. It said I didn't have IBD, when my UC had already been confirmed by sigmoidoscopy and biopsy. (Then why did I take the test? I've never had a full colonoscopy thanks to a weird bend at my hepatic flexure, so I wanted to try to rule out Crohn's.) I know of at least one other person on here (beartooth) who also got a negative result.

The Prometheus printout claimed about 90% accuracy for my results. My GI said he thought it was more like 80% at best. I worry about my own daughter, who's 5, but if she were 17, I don't think I'd invest in this test. I think Judilyn's advice is right on target.

I'd have to agree with all. If your daughter isn't showing any symptoms, why do the test? It really is expensive, and not completely accurate. UC can be/is genetic, but no one else in my family has it. Just because you have UC doesn't mean your daughter will. Let her live life and be happy, and if she one day shows symptoms, then start thinking about getting her tested.
