Formalin time is no less than 6 and no more than 48 hours. You need to document time from excision to time in formalin - cold ischemic time - and time in formalin. 

New regs extended fixation time for ER/PR to 72 hours, but since it's all in there together, you can't go by that yet. And for patient's to be eligible for many clinical trials, 10% NBF is the only fixative that should be used. j

  What is the appropriate time it should be in formalin?  Do you start your time when it is initially put into formalin, or the start from the time it was dissected?
