CD9, CD19, CD34, CD38, CD45, CD90, CD117, CD133, HLA-DR
This tube is added whenever >20% myeloid blasts are identified by flow cytometry (often when >10% blasts are identified), in order to provide additional characterization of the blasts. This tube can also be helpful in distinguishing benign regenerating myeloid blasts from leukemic myeloid blasts in the setting of post therapy bone marrows. This tube includes antibodies to CD45, CD9, CD133, CD34, CD90, HLA-DR, CD117, CD19, and CD38. Because of recent reports suggesting the prognostic significance of CD25 in AML, we are considering swapping the CD25 for the CD90.
