Special Instructions: To find the normals for other age brackets for the neutrophil, band, lymphocyte, monocyte, eosinophil and basophil cell lines, see their individual procedures. The differential is not part of the Hemogram and must be ordered as "CBCD," Hemogram and diff. Manual differentials will be performed when the results of the Instrument automated differential do not correlate with previous patient results or if there are instrument flags indicating questionable results that need visual confirmation/evaluation.
