Calculation of estrogen excretion rates from urinary estrogen to creatinine ratios.

摘要: 1. The excretion of estrogens by 42 menstruant and 7 pregnant (1st trimester) women ranged from 2 - 550 mug/24hr. 2. These changes were followed measuring estrogen to creatinine ratios in small samples urine. 3. Values the ratio changed little each 24 hr, correlated closely with daily output (r = 0.971; P less than 0.001; (mug/24hr) =(see article. 4. data suggests that ovarian activity women, including those given gonadotropins induce ovulation, may be urine; collection hr is unnecessary.
