Serum ferritin levels in iron deficient children.

A group of 42 iron deficient children had serum ferritin levels in the range of 0-19 micrograms/l, with a mean figure of 7.2 micrograms/l. A control group had levels of 11 micrograms/l to 130 micrograms/l with a mean of 39.8 micrograms/l. The use of this assay has particular relevance whilst iron deficiency anaemia continues to be a common disorder in New Zealand children.
