[Histonet] exhausting tissue blocks

[Dawn Cowie]

hello histonetters,
I was wondering what thoughts any of you have on the subject of cutting away and exhausting tissue blocks when doing recuts. We often get requests from our pathologists to cut deepers and exhaust the block ie: exhaust in 3 slides of deepers. Does anyone know of any reg's that cover this kind of thing? It really goes against the grain to cut away all the tissue. Plus, we are supposed to keep the blocks for 10 years. It defeats the purpose of doing so.
Any response would be appreciated.
Thanks,
Dawn Cowie, HT
