Diagrammatic representation of atypical haemoglobin cellulose acetate electrophoresis patterns at alkaline pH 8.4 to 8.6 showing some haemoglobin variants, including HbH and Hb Bart’s as fast-moving alpha thalassaemia bands. Others include: HbAA (Adult normal haemoglobin band), HbSS (sickle cell anaemia bands), Hb F (foetal haemoglobin bands), Hb SC (Sickle cell disease bands) and carrier traits (Hb E, D, C, S, O, G,CS etc). Hb CS, particularly, can only be identified when cellulose gel electrophoresis with heavy application is used
