Total estrogen is a measurement of overall estrogen status. Clinically this is important in evaluating symptoms of menopause, cardiovascular risk, and bone health in aging women.
Because estrogen hormones such as E1 and E2 fluctuate during a woman’s cycle and even in menopause, some doctors believe that the total estrogen measurement is a more reliable test of estrogen status.
Fasting is not required for this test. Take all medications as prescribed. If you are supplementing with any hormones, we suggest taking them approximately 2 hours prior to having your blood drawn to see peak levels. Hormones are best drawn between 8-10 AM. Hormonal contraceptives can interfere with progesterone and estrogen results.
Pre-menopausal women: For a 28 day cycle, blood should be drawn on day 21 (day 1 is the day that bleeding begins). For longer or shorter cycles, count 8 days back from the day your next menstruation would start.
Post-menopausal women: Blood can be drawn any day of the month.
This test does not include a breakdown of each individual estrogen level. If you are interested in knowing the blood levels of estradiol (E2) and estrone (E1), we suggest ordering the following individual tests:
