Screening for sickle cell disease in newborns: a systematic review

open access: yesSystematic Reviews, 2020
Background Sickle cell disease (SCD) is an inherited autosomal recessive disorder caused by the replacement of normal haemoglobin (HbA) by mutant Hb (sickle Hb, HbS). The sickle-shaped red blood cells lead to haemolysis and vaso-occlusion.
