We use the ThinPrep method in our lab for all specimens.  On specimens
that will have a cell block we make one ThinPrep slide.  On all others
we make 2 slides and then spin down the remaining specimen and make a
judgement call as to cellblock or cytospin.  If the case or dx dictates
the possibility of IHC staining we will make additional TP's or
cytospins for possible IHC staining.

Any specimen coming up dilute we usually make a cytospin too.  The
exception is usually the spinal fluid that was acellular.
