Author information: (1)Paediatric Haematology and Oncology, University Hospital Münster, Albert-Schweitzer-Str. What is acute lymphoblastic leukemia? In order to determine whether or not leukemia cells have spread to this area, a sample of the CSF is tested. The cells are then passed through a laser beam.

Acute lymphoblastic leukemia (ALL) is a clonal expansion of the lymphoid blasts in bone marrow, blood or other tissues. The hallmark of ALL is chromosomal abnormalities and genetic alterations involved in differentiation and proliferation of lymphoid precursor cells.
