Several lines of evidence support the view that premature rupture of the membranes and premature labor are associated with bacterial infection of the amniotic cavity. The standard method of diagnosing intraamniotic infection is amniotic fluid culture, but the results become available only after 72 hours. Methods for more rapid diagnosis of bacterial invasion are therefor needed. We examined leukocyte esterase activity for this purpose. Amniotic fluid obtained from 62 women in preterm labor was cultured for aerobic, anaerobic and mycoplasma species. Leukocyte esterase activity was measured with a Bio-dynamics test strip. The sensitivity of the test was 50.0% and its specificity 93.4%. It was found to be a simple and rapid method for the detection of intraamniotic infection.
有几条证据支持胎膜早破和早产与羊膜腔细菌感染有关这一观点。诊断羊膜腔内感染的标准方法是羊水培养，但结果要72小时后才可得。因此需要能更快速诊断细菌入侵的方法。我们为此检测了白细胞酯酶活性。从62名早产妇女获取的羊水进行了需氧菌、厌氧菌及支原体培养。用生物动力学测试条测量白细胞酯酶活性。该检测的灵敏度为50.0%，特异性为93.4%。它被发现是一种检测羊膜腔内感染的简单快速方法。
