Platelet Clumps (PLT-CLM, NW)
Definition
Presence of clumped platelets is suspected.
The Platelet Clumps flag is triggered if the Clumps Count in the PLT Clumps
region of the Perox cytogram is greater than 150. The PLT count is flagged to
alert the user that the platelet count may not be accurate due to the presence of
platelet clumps.
The PLT Clump area of the Perox cytogram originates in the Noise area and
extends upward to the right of the lymphocyte population. The number of events
obtained from this area is called the Clumps Count.
The Clumps Count is excluded from the WBCP and differential results.
There is no severity level associated with this flag.
