Perox No Valley (PX-NV, VX)
Definition
The Perox No Valley flag is triggered if there is no valid separation between the
noise and lymphocyte populations in the Perox cytogram.
The separation of the noise and lymphocyte populations along the y axis of the
Perox cytogram is evaluated by the relative depth of the valley (PEROX d/D)
between the two populations.
In normal samples, PEROX d/D is greater than 0.15. This flag is triggered if
PEROX d/D is less than 0.15.
