Hi all, I am a relatively new supervisor making my way through reviewing all SOPs.

I came across one policy concerning storage of patient samples, it says, " all samples are stored at 1-6C when not in use. ....Do not use a speciment for testing that has remained at room temperature for 8 hours."

I understand this in theory of extended time at room temp increases likelihood of bacterial growth if present. What I am trying to locate is a standard from either AABB or CAP that states this. Does such a standard exist or was it likely this was written based on common sense?

thanks for any thoughts......debbie

I've never seen any reg for how long it can be at room temp.

I agree with Terri. I think you can get rid of that statement. You may want to check on the 1-6 C requirement too. I think the standard is 2-8 C.

Debbie it sounds like were I just took over. Random things in procedures that you can find no reason for...

Yes PAWHITTECAR, I have made a number of revisions to bring policies in line with the way things are actually done. Thanks for your comment, always nice to know I am not in this boat alone!

I don't remember CAP or AABB regs either but you should check your reagent manufacturer's instructions.

Phil's right. A lot of times things like that come from the reagent manufacturers not the regulatory agencies.
