Panel proposal for the immunophenotypic diagnosis of hematological malignancies. A collaborative consensus from the groupe d'Etude Immunologique des Leucémies (GEIL).

After a cycle of meetings and discussions, members of the French Groupe d'Etude Immunologique des Leucémies obtained consensus on a series of immunophenotyping panels for hematological malignancies. The rationale of the markers chosen is depicted for each of them. This proposal comes for instruments with 8 or 10 colors. Care was taken to minimize the fluorochromes attached to any given specificity and to leave, whenever possible, some free slots for the cytometrist's choice.
