Serum iron level in acute lymphoblastic leukaemia.

Serum iron level (SIL) was studied by atomicabs orption spectrophotometry in 57 children with acute lymphoblastic leukaemia. SIL depended on the activity of the disease. Mean SIL was highest in untreated children. Normalization of myelograms during treatment was accompanied by a decrease of SIL. A significant decrease was observed in organ localizations and in infections during remission of the leukaemia. SIL may be helpful as an auxiliary test in the management of leukaemic children.
