Background :SCT results from inheritance of one gene for haemoglobin S and one for normal haemoglobin A. The heterozygous inheritance of the gene for haemoglobin S results in sickle cell trait or AS haemoglobin. Hb A is most abundant and the amount of haemoglobin S averages only approximately 30% in each red cell. Individuals who are heterozygous for Hb S are carriers of the sickle cell trait (SCT). Methods :A retrospective randomised comparative study of pregnancy outcome in sickle cell trait vs sickle negative patients. Total sample size taken 150. Patients are compared in regard with antenatal , intrapartum and post natal complications.
