Robert Guthrie

Robert Guthrie was an American physician and biochemist renowned for his pioneering work in newborn screening. In the 1960s, he developed the Guthrie test, a simple blood test that detects phenylketonuria (PKU), a genetic disorder that can lead to intellectual disability if not treated early. His work significantly advanced public health measures, allowing for early diagnosis and intervention, thereby improving outcomes for affected infants. Guthrie’s contributions laid the foundation for expanded newborn screening programs worldwide, enhancing the health and quality of life for countless children. His legacy continues to influence pediatric healthcare today.
