The quantification of 'faint-positive' cholinesterases in amniotic fluid was performed in 40 patients with positive acetylcholinesterase (AchE) tests. Fetuses with anencephaly and open spina bifida presented an AchE/butyrylcholinesterase (A/B) ratio of more than 0.3 with clearly dense bands. Fetuses with gastroschisis showed a 'faint-positive' AchE band (A/B < 0.3). In 5 fetuses (1 teratoma, 3 open spina bifida, 1 unaffected) we found faint AchE and butyrylcholinesterase bands.
