Pregnancy-associated plasma protein A (PAPP-A) was measured throughout the menstrual cycle in eight women at daily intervals. The protein could be detected in all serum samples, and one patient showed consistently high PAPP-A values during the entire observation period. Twenty-six more women were tested by measuring a single serum specimen. No further high PAPP-A levels were discovered in these. There is no significant difference in PAPP-A concentration between the follicular and the luteal phase of the cycle.
对8名女性在整个月经周期中每天测量妊娠相关血浆蛋白A（PAPP-A）。在所有血清样本中均可检测到该蛋白，1名患者在整个观察期内PAPP-A值持续较高。另外对26名女性检测了单个血清标本，未发现更高的PAPP-A水平。月经周期的卵泡期和黄体期之间PAPP-A浓度无显著差异。
