Evaluation of the use of the Hemalog D in acute lymphoblastic leukaemia and disseminated non-Hodgkin's lymphoma in children.

In 79 children with acute lymphoblastic leukaemia and in 18 children with disseminated non-Hodgkin's lymphoma we investigated whether the automated cytochemical differential leucocyte count (Hemalog D) gives more accurate information than the manual differential count. We concluded that the manual count is superior to the Hemalog-D count with regard to the recognition of blast cells. Furthermore, Hemalog D is not helpful for the differentiation between acute lymphoblastic leukaemia and disseminated non-Hodgkin's lymphoma.
