As a result of the multilineage nature of erythroleukemia, [13] the leukemic cells often express both erythroid and myeloid markers. They are often positive for myeloid markers, such as CD117, CD13, CD33, and MOP, whereas the expression of HLA-DR and CD34 is often decreased or absent. The megakaryocytes antigens CD41 and CD61 can be positive in some cases.

Erythroid markers such as glycophorin A and transferrin receptor (CD71 and CD45) may be increased, but they are negative in many patients with erythroleukemia. Therefore, whereas the expression of glycophorin A and/or transferrin receptor may be helpful, the absence of erythroid antigens does not exclude erythroleukemia.
