Abstract:
All newborns in Sweden are screened for phenylketonuria (PKU), among other things, blood usually being sampled by heel lancing. Because it is unnecessarily painful, however, this form of sampling in newborns has recently been questioned. There is reason to recommend sampling from a dorsal hand vein as the method of choice for PKU screening purposes.
