I asked a C. diff. expert these questions as many docs. disagree. I trust his answers above all others.
Q. How long to retest after Flagl/vanco/Dificid during active C. diff.?
A. 7 to l4 days and the longer the better. PCR is false positive for up to two weeks as bits of DNA from killed C. diff. are passed out, and if tested too soon gives a false positive result. Culture early is accurate but not easy to get done by labs.
This means completely off c diff meds.

Re: Testing
Thank you for this post. I am waiting to do my 3rd test after taking Dificid. Doctor said no sooner than 14 days after my last dose but I was wondering if I should wait even longer.

If you don't have symptoms you don't test.

Re: Testing
Roy is right ,testing without symptoms is pointless. If nothing bothers you and you end up with a positive test , would you treat?
