In reply to Rekha Shah regarding a differential count using flow
cytometry. There is an excellent article by Lauralynn Lebeck in the
1993 Sysmex Journal International, Vol. 3 No 1, p 61-69.

In a nutshell, this looks at CD45, CD13, CD14, FSC and SSC. This
correlates well with the traditional manual dif for neutrophils,
lymphocytes, and eosinophils. Monos are slightly higher, owing
largely to a preferential loss of monos in the traditional wedge
smear. Monos (by flow) correlate well with the "spun blood film prep"
method, which is less hazardous to their health.

A slightly adapted version of this has become our method of choice.
