A simple and accurate method for measurement of the hemoglobin content in blood by colorimetric iron determination.
A simple and accurate determination of iron in blood involving acid digestion in a heating block is described. The digestion requires little attention and permits the handling of large numbers of samples. The diluted digest is used for the colorimetric determination of iron using o-phenanthroline, and the equivalent hemoglobin in blood is calculated. There was a good correlation between the results of the present method and the cyanmethemoglobin method with 21 standard blood samples containing 4.9-26.8 g/dl of hemoglobin.
