WBC Reclassification for Peripheral Blood
Besides the cell classes mentioned above, the operator can reclassify cells into the
following classes: Immature eosinophils, Immature basophils, Promonocytes,
Prolymphocytes, Large granular lymphocytes, Hairy cells, Sézary cells, Other,
Megakaryocytes, Not classed and 15 user defined cell classes.
Other should be used for cells which the operator identifies as a WBC, but of a
type other than those listed. WBCs put here will be included in the differential
count.
Not classed should be used for cells and objects which the operator cannot identify
and wants to exclude from the differential count.
RBC Precharacterization
The system precharacterizes the following RBC morphology characteristics in an
overview image: Polychromasia, Hypochromasia, Anisocytosis, Microcytosis,
Macrocytosis and Poikilocytosis.
RBC characterization
The operator can characterize to Target cells, Schistocytosis, Helmet cells, Sickle
cells, Spherocytosis, Elliptocytosis, Ovalocytosis, Tear drop cells, Stomatocytosis,
Acanthocytosis, Echinocytosis, Howell-Jolly bodies, Pappenheimer bodies,
Basophilic stippling, Parasites and 10 user defined characteristics.
Platelet Estimation
The operator counts or estimates platelets in an overview image.
Sample Preparation
To perform a peripheral blood differential count a thin blood film is wedged on a
glass slide (a blood smear) from a peripheral blood sample and stained with
Romanowsky stain (see Appendix G — Slide Preparation Guidelines
) for
recommended staining recipes).
