Because it seems unfortunate that misunderstandings in some places have delayed the inauguration of screening programs for phenylketonuria (PKU) in newborns, I am sending this or a similar letter to the editors of five or six medical journals. It occurred to me that a preliminary published note regarding the 10-month experience of Massachusetts in the nation-wide PKU newborn screening project might be of value to physicians and health officers of other states, especially in states not presently participating or participating only on a limited basis.
