Three questions:

1. What is the correct(legal) way to dispose of dated surgical slides?
(dumpster or biohazard)


2. Is it possible to stain for her2neu on previously stained slides. Not
the blocks!


3. What is the general consensus out there on surgical slide and block
storage. Legally blocks must be kept 5 years and slides 10 years. I
understand keeping them over this required time increases your
liability, but I have some stubborn pathologists wanting to keep them
7-10 years. Any info would be helpful.

Thanks.
