Resistant RBC
Figure 5.37 Run Screen for Resistant RBC Counts
The
[RESISTANT RBC]
key is used to select the Resistant RBC specimen type. This
cycle is used to process samples containing RBCs that are resistant to lysis. The
sample is held in the WBC Mixing Chamber for approximately 15 seconds longer
than the normal mixing time. The extra time enhances the osmotic lysing effect of
the WBC lyse and reduces interference from the lyse-resistant RBCs. (The
interference caused by these RBCs frequently generates WBC and Differential
flags. The Resistant RBC mode reduces the number of flags generated.)
The
RESISTANT RBC
screen (refer to Figure 5.37) is similar to the Patient screen
except that “ResRBC” replaces “Name” in the Demographics Section.
