Guthrie card

A Guthrie card is a special card used to collect a small blood sample from a newborn's heel shortly after birth. This blood is dried on the card and sent to a laboratory for screening tests that can detect certain genetic, metabolic, and developmental disorders. Early detection allows for timely treatment, helping prevent serious health problems or developmental delays. Guthrie cards are a standard tool in newborn screening programs worldwide, ensuring infants receive necessary care from the start of life.
