My mother has been suffering from recurring C-diff for over a year. They told her that this was the next step and want to test me as a donor. Of course I pointed out that when I was a teenager my dad regularly told me he’d had enough of my sh*t. Go figure.
My mother also fought C-Diff for a while. It ended up subsiding just as we were about to make arrangements for a fecal transplant.
I hope your mother recovers soon. Best Wishes
