[Histonet] Re: Tracking Floaters


We had the same problem at my previous job.  The PA was grossing  
smaller specimens and placing the cassettes into a large container  
with formalin.  Then the PA was grossing the placentas and adding  
these cassettes into the same holding container.  The problem was  
fixed by keeping the placenta cassettes in a separate container.  At  
the end of the day, everything was loaded into the processing basket  
and placed into the processor.  This seem to have eliminated any  
further contamination with placenta parts.  Please note that we did  
not at any time mix the formalin of the containers.
