This test only performed in conjunction with CFX (cell counts).

This test is a pathologist's examination of an air-dried wright-stained 
slide prepared on a cytospin.  The specific reason for the examination 
must be noted on the requisition.  A written interpretation by a 
pathologist is reported by computer.  Specimens suspicious for 
malignancy should be confirmed with pap stained millipore cytology or 
tissue biopsy.  These slides are held in a permanent file for future 
reference.

A CSF Cell Count is necessary to order this test.
