Placental protein 14 (PP14) can be measured in the serum by radioimmunoassay. The level rises from mid to late luteal phase in a manner similar to the endometrial biopsy. A study was initiated to determine if a clinical association could be found between the late luteal phase serum PP14 level and subsequent pregnancy and spontaneous abortion rate. No difference was found in the preconception PP14 level in patients conceiving versus those not conceiving, nor in those aborting versus those not aborting. A trend toward higher levels in conception versus non-conception cycles was noted, but a large patient group will be needed to demonstrate statistical significance.
胎盘蛋白14（PP14）可通过放射免疫测定法在血清中进行检测。其水平在黄体中期到晚期呈上升趋势，与子宫内膜活检的情况类似。启动了一项研究，以确定黄体晚期血清PP14水平与后续妊娠及自然流产率之间是否存在临床关联。在成功受孕的患者与未受孕的患者之间，以及发生流产的患者与未发生流产的患者之间，孕前PP14水平均未发现差异。虽然注意到受孕周期与未受孕周期相比有PP14水平更高的趋势，但需要大量患者群体才能证明其具有统计学意义。
