"Floaters represent a potential source of diagnostic error and occur in 0.01% to 1.2% of slides. Pick up of floaters from the water bath appears most common (∼60%). Floaters in only 1 level and mismatch with the specimen tissue type are clues to the extraneous nature of the floater."

I am posting this question for a colleague in our Cytology department.     How often do you see floaters on surgical or cytology specimens?    Obviously we would never want to see any type of carryover but is there a standard rate published somewhere that he can reference?

Thanks in advance for your help.
