title: [Optic density at 650 nm and phosphatidylglycerol in the evaluation of fetal pulmonary maturity].
abstract: The authors studied the correlation between optical density at 650 nm (OD650) and phosphatidylglycerol (PG) in 52 samples of amniotic fluid obtained by amniocentesis in which the shake test was negative 22 out of 52 samples (42.3%) had detectable amounts of PG (> or = 2%). Our results clearly demonstrate that OD650 is unable in predicting the presence of absence of PG in those immature samples of amniotic fluid according to the shake test.
