Human placental lactogen (hPL) is commonly used in surveying the placental function during normal and pathologic pregnancies. This report describes a pregnancy where hPL could not be found in maternal serum or placental tissue. The pregnancy was in all other respects completely normal, ending with the birth of a normal baby. Some possible reasons and consequences of this unique event are discussed.
人胎盘催乳素（hPL）常用于评估正常和病理妊娠期间的胎盘功能。本报告描述了一例在母体血清或胎盘组织中未检测到人胎盘催乳素的妊娠病例。该妊娠在其他方面完全正常，最终产下一名健康婴儿。本文讨论了这一独特事件的一些可能原因及后果。
