Good Afternoon Listers,

Thanks to all who answered my question about retention of unstained
slides.  I had several people weigh in on the topic and we have created an
unstained slide policy based on their advice and the literature that was
kindly sent to me.

The consensus is antigenicity degrades depending on storage conditions,
among other things, which can lead to false negative results (antibody
dependent - but not worth the risk).  We now will keep unstained slides
which have been stored at room temperature no longer than 12 weeks.  One
really good suggestion that will are implementing is if a pathologist wants
the slides kept longer than 12 weeks, they get to keep the slides in their
possession.  We will enter a note in our LIS stating who has the unstained

The wisdom of my electronic colleagues comes through once again.
