Platelet Aggregation


This sample was a more distinct example of platelet aggregation. The NWBC flag was set and was accompanied by an URI flag, indicating interference in the region between the PLT and RBC populations. This interference was clearly visible in the 0º/RBC 10º scatterplot as a cluster of black events above the platelets and was strongly suggestive for the presence of platelet aggregation.


When a low platelet count is detected in combination with the NWBC and URI flag, it is advised to check the sample for the presence of platelet aggregation.
