We did use freeze spray in the cryostat years ago. Then one fateful day we all
had to go on protocol for exposure to TB because a resident sprayed a lung with
the freeze spray and there you go. There is a turn around time for frozen
sections we are all working with, HOWEVER it is not worth

I have to agree with Terri. I also believe that CAP is going to be putting
in regulations forbidding the use of freeze sprays in cryostats soon (at
least I think I heard a rumor about this).
Anyway another useful item is liquid nitrogen if you really need a quick

Is the 30 seconds you save in using freezing spray worth the exposure to TB or
goodness-knows-what?
We use a simple metal heat extractor (comes standard in our Leicas) and
Our hospital has not allowed freezing spray to be used in the frozen section
lab for many years. We now have a new group of doctors who want to use the
spray. The docs think the frozen sections take too long to freeze. Yet, they
meet the frozen section TAT for more than 98% of our cases. I

RE: [Histonet] Freezing spray artifact
