WebSickle cell trait occurs in heterozygotes where approximately 40% of the haemoglobin is HbS, the rest being HbA, which interacts only weakly with HbS during the processes of gelation. The heterozygote has little tendency to sickle except under conditions of severe hypoxia, ie when saturation is less than 40%. WebOct 14, 2016 · Sickle Cell Trait.
