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.
瑞典所有新生儿都要进行苯丙酮尿症（PKU）筛查，除其他项目外，通常通过足跟采血进行血液采样。然而，由于这种采样方式会给新生儿带来不必要的痛苦，近来受到了质疑。有理由推荐从手背静脉采血作为苯丙酮尿症筛查的首选方法。
