Paper-Based Diagnostics: Rethinking Conventional Sickle Cell Screening to Improve Access to High-Quality Health Care in Resource-Limited Settings.

Every year, hundreds of thousands of children worldwide are born with sickle cell disease, a genetic disorder that impacts the hemoglobin molecules in blood. If left undiagnosed and untreated, most affected children will die before reaching the age of five. However, highly accurate diagnostic methods and effective treatment regimens for sickle cell disease have been known for many years, and children who receive early diagnosis and subsequent comprehensive care survive well into adulthood-as evidenced by the tremendous success of universal newborn screening programs in North America and Europe.
