This study confirms that the BC DURAClone ALB and CLB panels are suitable to provide additional second-line immunophenotypic workup of precursor B-ALL and mature B-cell lymphoproliferative disorders resepectively, at disease presentation and are suitable to supplement first-line ClearLLab 10C laboratory predicate method testing. This evidence concerns the gene ALB and precursor B-cell acute lymphoblastic leukemia.
