ClearLLab LS CaseBook

This CD20/CD19 dot plot is gated on Lymphocytes. A small population of unremarkable B lymphocytes is present.

This CD34/CD10 dot plot is gated on Lymphocytes. These cells are essentially negative for both markers, as expected for both normal mature peripheral blood lymphocytes as well as mature lymphoproliferative disorders.

This CD19/CD10 dot plot is gated on Lymphocytes. A small population of unremarkable B lymphocytes is present.

This CD5/CD19 dot plot is gated on Lymphocytes. Two populations of CD5 positive T lymphocytes can be seen, with the higher density CD5 corresponding to normal cells and the lower density CD5 corresponding to the aberrant population.
