Fifty Years of Newborn Screening for Sickle Cell Disease: A Call for Sickle Cell Trait Counseling

Lay Summary As we celebrate 50 years of newborn screening (NBS) for sickle cell disease (SCD), we must confront its hidden failure: the neglect of sickle cell trait (SCT). Identified in thousands of newborns annually, SCT status is often lost in a system with no clear owner for communicating its lifelong implications to families. This gap leads to missed opportunities for reproductive planning, widens health disparities, and undermines public trust. We present public health precedents that provide a pathway to integrating SCT counseling into routine care and urge stakeholders to move beyond identification to action and fulfill the original promise of NBS.
