NBT tests performed on simultaneously drawn venous and capillary blood from 56 patients showed a considerably lower proportion of NBT positive neutrophils in capillary blood than in venous blood. The presence of serum was necessary for the NBT test to function and fresh serum was more efficient than inactivated serum. Haemolysed blood reduced the proportion of NBT positive neutrophils and this may explain, at least in part, the observed difference between venous and capillary blood.
