The urinary pregnanediol and creatinine excretions in females of menstrual age were correlated. The high degree of correlation found allows the use of the pregnanediol/creatinine ratio of the first-morning voided urinary specimen in calculating, with a fair degree of precision, the 24-hr. pregnanediol excretion.
处于月经年龄的女性尿液中孕二醇和肌酐的排泄量具有相关性。所发现的高度相关性使得可以利用首次晨尿样本中的孕二醇/肌酐比值,较为精确地计算出24小时孕二醇排泄量。
