If you already have the cell block you can put it in the tissue processor. You do not need to re-fix it, but it will when going through the formalin stations in the tissue processor, and that OK and enough.

Good Morning-
Scenario:  a specimen is received and has been in cytology fixative overnight - a cell block is made from (very small) tissue picked out.

1.        Can this be run on a program without formalin?

2.      Does this need to be in formalin before going on the processor - if so how long?
I appreciate any thoughts you may have,
Nancy
