Nitroblue tetrazolium test (NBT) and bactericidal activity of polymorphonuclear leucocytes was studied in 40 patients with iron deficiency anaemia (aged 012 years). NBT test had a significant correlation with serum iron (P< 0.001) in all cases of iron deficiency anemia. Haemoglobin levels <4g/dl also correlated significantly with NBT score. Bactericidal activity with opsonin-coated Staphylococcus aureus was considerably decreased in severe anaemia, but no significant correlation was found with serum iron concentration (P<0.1). The phagocytic and bactericidal activity of polymorphonuclear leucocytes is dependent upon serum iron levels and is considerably reduced in iron deficient state in anaemic children.
