A newborn in Ohio is screened for homocystinuria. A newborn in Oregon is not, but is screened for biotinidase, something that isn't part of the screening panel in Ohio. Newborns in Massachusetts are screened for 11 congenital conditions; in South Dakota, for only three.
This is the crazy-quilt status of screening the estimated 4,000,000 infants born annually in the United States and a major reason a task force has published a report outlining the issues public health officials, parents, physicians, and politicians should resolve in this arena (Pediatrics. 2000;106(suppl):383-427).
