Abstract
The date of delivery in 62 normal pregnant women was predicted by last menstrual period, by ultrasound scan and by the serum concentration of Schwangerschaftsprotein 1 (SP1). It was found that SP1 concentration in the first trimester gave as reliable an indication of when labour would occur as did the last menstrual period or ultrasound scan.
摘要
通过末次月经、超声扫描以及妊娠相关蛋白1（SP1）的血清浓度，对62名正常孕妇的分娩日期进行了预测。结果发现，孕早期的SP1浓度与末次月经或超声扫描一样，能可靠地指示分娩时间。
