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:
Life Extension® also offers a 24 hour urine test for the three major estrogens (estrone, estradiol and estriol) and their metabolites:
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 estradiol and estrone 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.
