title: Diagnosis of decreased cholinesterase activity by amniocentesis.
abstract: We report a case in which amniocentesis, performed in order to exclude a fetal chromosomal abnormality, led to a diagnosis of decreased cholinesterase activity. This is a rare but clinically useful application of the amniotic fluid cholinesterase assay.
