Objectives: To describe the immunophenotypic and laboratory features of a cohort of Sri Lankan children and adults with ALL and to compare them with those reported in other series.
Methods: Records of 229 patients who were suspected of having acute leukaemia and referred for flow cytometry to the Asiri Hospital Sri Lanka, between August 2009 and October 2013 were reviewed.
