re:[Histonet] Isopropyl (again)
|From:||"Stephen Peters M.D." |
I cannot help you with the isopropal question. But let me ask you are you trying to speed
up your turn around time on breasts or are you having trouble cutting under processed
If you are trying to speed up turn around time you picked a bad tissue to be in a
rush with! Reading a miserably processed breast specimen is a frustrating and risky
buisness frought with potential legal repercussions. I think your pathologists would
agree with this. I suggest a little patience. If the surgeons are busting their chops it is time
for a little histology lesson for the surgeons. I like to tell my surgeons I will be be happy to give a rush diagnosis, but if they would like the correct diagnosis that will take a bit longer!
If poorly processed tissue is the problem then it is a matter of all the things you already know. The sections should be cut no more than 3mm thick across the entire section
( not just the edge). Once cut sections should be give adequate fixation in clean
formalin before putting it in the processor. Over night if possible. Processor solutions should
be clean and changed at appropriate intervals. Baskets should not be overstuffed if possible especially with, cassettes filled with large samples. If you have multiple processors at your disposal you may want to sequester these cases an adjust the program and solution
changes until you are satisfied with the result.
If your grossing staff leaves intact specimen sit overnight in the fixative it arrived in and
then cuts it the next day, fixation will often not be adequate because inadequate amout
of formalin, formalin which has been weakened by dilution or inability of the formalin
to penetrate and fix a thick piece of tissue.
I am sure you already know this . Make sure your grossing staff do to.
