The predictive values of plasma progesterone levels in 70 patients threatening to abort was investigated. It was found that no patient aborted whosed plasma progesterone level remanined above 35 nmol/l between 7 and 16 weeks of pregnancy, whereas if the plasma progesterone level was less than this, subsequent abortion always occurred. The predictive value of cornification index in vaginal smears was also examined: many smears were unsatisfactory for assessment and in patients with threatened abortion there was a 14 per cent incidence of falsely optimistic and 29 per cent of falsely pessimistic predictions.
对70例有流产先兆患者的血浆孕酮水平的预测价值进行了研究。结果发现，在妊娠7至16周期间，血浆孕酮水平保持在35 nmol/l以上的患者无一发生流产，而如果血浆孕酮水平低于此值，则随后总会发生流产。还检查了阴道涂片角化指数的预测价值：许多涂片评估不满意，在有流产先兆的患者中，假阳性预测发生率为14%，假阴性预测发生率为29%。
