Flow cytometry

Flow cytometry analysis of peripheral blood.  The blasts (red) represent approximately 43% of the WBC and are dim to negative for CD45; positive for CD19, CD34, CD10(bright), CD22, HLA-DR, and CD58; and negative for CD20, CD117, CD13, CD33, and surface light chains.   This immunophenotype is typical for B lymphoblastic leukemia (B-ALL).
