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 biospy. These slides are held in a permanent file for future reference. A CSF Cell Count is necessary to order this test.
