In both clinical practice and clinical trials, remission in leukemia is determined by morphological assessment — a person counting cancer cells in a bone marrow sample under a microscope. But more sophisticated technologies, such as flow cytometry, could help overcome many of the limitations of morphological assessments.

But what happens when the morphological assessment indicates remission and the flow cytometry results suggest cancer?
