I was misdiagnosed with UC when I really had c-diff. I insisted on a c-diff test, though my doctor thought that was certainly not necessary as I was an otherwise healthy adult. I was put on pred and went on vacation, only to get a call that, yes, I was positive for c-diff, so I took Flagyl (and took Flagyl again, and finally got rid of the sucker with Vanco).
I would not at all be surprised that you still have c-diff. It is quite common to get a false negative, but you will never get a false positive. Since Vancomycin is so very expensive, and it is a drug of last resort, I would see how your symptoms are over the next few days to a week and/or insist on a stool test, and if you felt you still had your c-diff, I'd take the vanco. It will probably take care of the c-diff problem.
I was hoping that with this diagnosis, I did not have UC after all. Unfortunately, a year later or so, I was diagnosed with UC and now take Azathioprine every day to treat it (quite successfully, I might add).
Good luck to you!
