title: Elevated levels of maternal plasma alpha-fetoprotein after amniocentesis.
abstract: An elevation of maternal AFP levels was observed in 11 of 65 cases (17 per cent) after amniocentesis. It is suggested that blood samples in which AFP levels are to be measured should always be collected before and not after amniocentesis.
