A sensitive method for assay of phosphate has been adapted for use with human amniotic fluid. The presence of an antibacterial factor in amniotic fluid inactivated by phosphate suggested that measurement of free phosphate may predict antibacterial activity and hence susceptibility to intrapartum infection. The intrinsic antibacterial activity of amniotic fluid was altered by addition of large amounts of phosphate, but the intrinsic concentration of free phosphate correlated poorly with antibacterial activity and organically combined phosphates did not appear to be related to the antibacterial property.
一种灵敏的磷酸盐测定方法已被适配用于检测人羊水。羊水中存在一种被磷酸盐灭活的抗菌因子，这表明游离磷酸盐的测量可能预测抗菌活性，进而预测对产时感染的易感性。通过添加大量磷酸盐可改变羊水的固有抗菌活性，但游离磷酸盐的固有浓度与抗菌活性的相关性较差，且有机结合的磷酸盐似乎与抗菌特性无关。
