Abstract
ALTHOUGH oxyhaemoglobin is oxidized by nitrite to methaemoglobin, carboxyhaemoglobin is not. This difference can be used to demonstrate the presence of carboxyhaemoglobin in single erythrocytes of a blood smear, simply by extending the methaemoglobin- (cyanmethaemoglobin-) elution technique of Kleihauer and Betke1.
