Baso No Valley (B-NV, VB)
Definition
The Baso No Valley flag is triggered if there is no valid separation between the
mononuclear (MN) and polymorphonuclear (PMN) populations in the Baso
cytogram. The B-NV (VB) flag is not triggered if agreement between the baso
and perox results is indicated by both the following conditions:
•
WBCB and WBCP agree within specified limits (No WBC-CE flag)
•
[(%NEUT + %EOS) - %PMN] is between 0 and 7.5
Separation of the MN and PMN populations along the x axis of the Baso
cytogram is evaluated by the relative depth of the valley between the two
populations.
In normal samples, the relative Baso d/D is greater than 0.15. The B-NV flag is
triggered if the relative depth is less than 0.15 and there is no agreement between
perox and baso results.
