Erythroid Gate

Erythroid cells are agranular with round nuclei and low cytoplasmic complexity. As such, they have a low side scatter. They are CD45 negative.

Differentials for populations in the erythroid window include:

• Normal nucleated red blood cells.
• Pure erythroid leukaemia.
• Myelodysplastic syndrome.
• Plasma cells.
• Leukaemia cells (typically precursor B lymphoid leukaemia).
• Non-haematopoietic cells.
