WebIn this method the hemoglobin determination is based upon a standard acid hematin solution, and it is quite definitely established that all blood hemoglobin contains the same hematin. The accuracy of the acid hematin method has again been established by the measurement of the oxygen capacity of rat blood. SUMMARY AND CONCLUSIONS 1. WebHemoglobin concentration was determined by the alkaline hematin method 66, and the absorbance at 580 nm determined in spectrophotometer (Ultrospec 3100 Pro, Amersham Biosciences, UK).
