Performance Characteristics
Typical Precision
Within Sample
The pooled precision values (CVs) for the Hemogram parameters, shown in
Table 4.14, are based on the analysis of data from N = 20 replicate runs based on
the same sample.
NOTE: N=20 is based on one whole blood sample aliquotted into 4 tubes, with
each tube run 5 times.
The data was obtained from several CELL-DYN 3200 systems over a period of
weeks. These precision values represent the typical performance from instruments
that are maintained properly, are operating in acceptable environmental conditions
and are using only recommended reagents and supplies.
