Estradiol is the strongest of the three estrogen hormones and is one of the most important hormones in a woman for a healthy and normal menstrual cycle, ovulation, and fertility. Estradiol is naturally produced in both genders with much higher levels in females. It is predominantly produced within the ovarian follicles, but also in other tissues, such as the adrenal glands, fat, liver, breasts, brain, testes, and placenta (during pregnancy) (1).
Abnormal estradiol levels can lead to health issues in both males and females. Symptoms of high estradiol can include:
- Diminished sex drive
- Weight gain
- Fertility issues
- Increased cancer risks (e.g., breast and uterine cancers)
- Development of breast tissue in males
Symptoms of low estradiol can include:
- Skeletal issues (e.g., osteoporosis)
- Delayed puberty in females
- Mood swings
Testing your estradiol levels is quick and easy
We offer several different tests to measure your estradiol levels. These tests just require a small blood sample collected from a simple finger prick in the privacy of your own home. Test results are available through our online portal, thereby avoiding the need to make any doctor or lab appointments. Of course, you may also wish to discuss your results with your healthcare professional, and this is highly recommended if you receive any results that fall outside the normal range.
The Estradiol (E2) test measures just your estradiol levels. For females of reproductive age, it is helpful to know what stage of your menstrual cycle your sample was collected at, as normal levels vary throughout each cycle.
There are various combination tests available for females that include estradiol along with other important hormones:
- Women’s Fertility Panel (5 biomarkers)
- Women’s Health Hormone Panel (12 biomarkers)
- Women’s Hormone Panel (E2, FSH, LH, Prolactin)
- Women’s Perimenopause Panel (E2, FSH, LH)
- Women’s Postmenopause Panel (E2, P4)
Males may wish to order the Estradiol (E2) test (estradiol alone) or the Men’s Health Hormone Panel (6 biomarkers), which includes estradiol along with other hormones that are important for male health.
