Did you know:
The PKU test was the nation’s first newborn screening test. Developed with the help of March of Dimes, the test has been routinely administered since the 1960s, sparing thousands of children from mental retardation.
PKU (phenylketonuria) is an inherited disorder of body chemistry that, if untreated, causes mental retardation. Fortunately, through routine newborn screening, almost all affected newborns are diagnosed and treated early, allowing them to grow up with normal intelligence.
At least 1 baby in 25,000 is born with PKU in the United States.
