Lab order says Calprotectin, Fecal. I can't believe the lab notes say room temp and then refrigerate after 24 hours. When I called her Doctor to confirm they said freeze, the lab I'm using is closer to home than driving to the Hospital where she goes. I'll drive over to the lab as soon as they open tomorrow to drop off. I would have thought lab would say refrigerate immediately at a minimum.What test ?
We have done both
For fecal cal
We have frozen it and other times refrigerated it
They will ship
It frozen to the outside lab to be completed most times
I know, that's what is so odd to me! The fridge versus freezer I get, but up to 24 hours at room temp seems wrong to me!We've also received conflicting info in the past with regards to freezing or refrigerating, which leads me to think that probably both are OK. I've never heard of being able to keep a sample at room temp for 24 hours, though.
Thank you so much! Great info to know. I hope I allowed enough time for her results to come back before her appointment in 9 days.ahhh Fcp my favorite topic!!!
Actually for Fcp test the sample stays viable at room temp for up to 7 days. Problem is most labs have to ship it off for testing. It stays on bench for a few days. So, unless you are handing it in same day best to freeze or refrigerate it. They say it doesn't much matter which way you go but we always opt for freezing. Freezing or refrigerating will not affect the sample. But too many days at room temp will. So I always err on the side of caution.
