Chapter 3 Principles of Operation
Action:Review a stained smear for nucleated red blood cells, platelet
aggregates, sickle cells, or other abnormal cell types and follow
your laboratory's review criteria.
If NRBCs are present, they should be quantitated according to your
laboratory's procedure; correction of the WBC count is not required,
however.
When the NRBC and WBC flags are set concurrently, RBCs resistant to
the lytic action of the sheath reagent may be present. Repeat the sample
using the Resistant RBC specimen type.
