Early identification of sickle cell anemia (SCA) with newborn screening enables antibiotic prophylaxis for Streptococcus pneumoniae, which is one of the early life-threatening complications of untreated disease. Identifying newborns with SCA also facilitates the education of parents and caregivers about early treatment of crises and prevention of complications. Newborn screening might also detect other hemoglobin (Hb) variants in children, including HbC, HbD, and HbE; however, newborn screening does not test reliably for other hemoglobinopathies, such as β-thalassemia or HbH disease. Hemoglobinopathy screening should therefore still be offered to those parents from high-risk ethnic backgrounds, ideally before or early in pregnancy.

Bottom line

In some provinces, newborn screening for SCA is available, facilitating early interventions to prevent complications.
