[Neonatal screening for mucoviscidosis using the BM-test-meconium].

In the Federal Republic of Germany screening for cystic fibrosis by the albumin content of meconium (BM-test) is performed on most newborns. In this paper arguments for and against this test are discussed. Arguments in favour of BM-test-screening are the possibility of early diagnosis, early treatment and genetic counseling. Drawbacks of the test are false positive and false negative results. The authors conclude that this screening test should not be performed.
