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.
作者们研究了通过羊膜穿刺术获取的52份羊水样本中650纳米处光密度（OD650）与磷脂酰甘油（PG）之间的相关性。在这52份样本中，52份样本中有22份（42.3%）的震荡试验结果为阴性，且可检测到PG（≥2%）。我们的结果清楚地表明，根据震荡试验，OD650无法预测那些羊水未成熟样本中PG的有无。
