[Histonet] Frozen sections

[Snyder, Wendy]

Hello,
  I was wondering about a policy for the length of time a frozen section
block can safely remain in a cryostat before it is taken out and routinely
processed.  I have a pathologist that wants to leave the frozen tissue block
in the cryostat for up to 3 days in case he wants to do immuno stains from
it.  I would be interested to here of other policys from other institutions
regarding this issue.

Thank you,
