Acute myeloid leukaemia: How to combine multiple tools.

abstract：INTRODUCTION:Capillary electrophoresis (CE) is a high-resolution method for detection of hemoglobin Constant Spring (Hb CS). METHODS:The levels of Hb CS quantified by CE were compared among three groups of samples including heterozygote and homozygote of Hb CS as well as Hb H-CS disease classified by DNA molecular dia...
