Newborn Screening for Sickle Cell Disease and Thalassemia.

Importance: Hemoglobin disorders are a considerable public health issue with more than 500 000 affected infants born annually worldwide. First introduced in the 1970s, newborn screening (NBS) for sickle cell disease (SCD) was included in the Recommended Uniform Screening Panel (RUSP) in 2006, a successful public health promotion and prevention practice that has led to improved childhood survival. Although SCD is the primary target, the screening process also detects many other hemoglobinopathies.
