Method Description

The Sysmex XN platelet fluorescent (PLT-F) analysis is based on flow cytometry method using a semiconductor laser, a two-dimensional scattergram is plotted, with the X-axis representing the intensity of the side fluorescent light, and the Y-axis representing the intensity of the forward scattered light. The scattergram displays groups of platelets, part of red blood cells, part of white blood cells, and debris.

 

The immature platelet fraction (IPF) is obtained as a ratio of platelet count in the area with strong fluorescent light intensity in the PLT-F scattergram (IPF zone), to the total platelet count.(Instruction manual: Automated Hematology Analyzer XN series [XN-9000/XN-9100] North American Edition.
