The Identification of Five Haemoglobin Variants in Bloodstains

Using a technique derived from work by Robinson et al. (1957) the differentiation of haemoglobin A/S (Hb A/S) from haemoglobin A/D (Hb A/D) and also haemoglobin A/C (Hb A/C)from haemoglobin A/E (Hb A/E) in bloodstains is reported. This method can also be used to obtain an improved separation of haemoglobin F (Hb F) from haemoglobin A (Hb A).
