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
