美国国家儿童健康与人类发展协会的理查德·莱文博士和他的同事通过对比120名最终出现子痫前症的妇女和118名没有出现子痫前症的妇女的尿样,结果发现,在前者的尿样中,一种被称为胎盘成长因子的蛋白质水平极低。研究者认为,通过分析这种蛋白质水平,有望提前几周甚至几个月的时间预知此妇女是否易发生子痫前症。 Dr. Richard Levine, of the National Association for Child Health and Human Development, and his colleagues compared urine samples from 120 women who eventually developed preeclampsia and 118 women who did not show preeclampsia. In the former urine sample, a protein known as placental growth factor is extremely low. The researchers believe that by analyzing this level of protein, it is expected a few weeks or even months ahead of time to predict whether this woman is prone to pre-eclampsia.
