Whoa! This is an old post. But I'm curious to find out if your test came out accurate after freezing? And if it was a EIA test or PCR. I've been reading so many different g info on freezING the sample. I'll be in the same situation next week as I can't see my doctor until next week, which means I'll be collecting my sample on a Friday and can't turn it in until Monday. Mine will be the EIA test.

Re: Collecting stool sample for c.difficile
Hi, NJoy! This post is indeed old so you might have better luck sending the original poster a private message. The EIA test is only about 60 percent accurate and isn't used as much anymore. Ask for a PCR or GDH test if you can. The PCR is about 96.9 percent accurate and detects active, as well as non-active infections (so you should only test if you have symptoms). The GDH is an antigen test and also very accurate. Hope you are negative and feel better soon!

Re: Collecting stool sample for c.difficile
There was no PCR tests in 2007.
Between Friday and Monday someone with c.diff would be able to produce 20+ samples.
C.diff toxins degrade at room temperature.
A fresh sample is best.
It has to be chilled if not tested within 4 hours or frozen if not tested within 24 hours.
