We evaluated the reproducibility of plasma hormone levels over time in 79 healthy postmenopausal women, ages 51-69 years at baseline, who were not using postmenopausal hormones.

We assessed plasma levels of estradiol, free estradiol, percentage of free estradiol, bioavailable estradiol, percentage of bioavailable estradiol, estrone, estrone sulfate, sex hormone-binding globulin (SHBG), androstenedione… CONTINUE READING
