The Estradiol test, sometimes known as an E2 test, measures the blood level of estradiol. Made by various tissues in the body, estradiol serves important roles in both men and women.
In women, estradiol is important in the growth and maintenance of organs related to sex and fertility such as the uterus, breasts and fallopian tubes. Once out of childbearing years, estradiol still has importance in regulating bone and joint health and the fat distribution. The blood level of estradiol as measured by the Estradiol test will usually vary at different stages pregnancy and at difference ages of life.
In men, estradiol, while typically existing at lower levels, still has an important role. Estradiol helps maintain sperm cell health and does have a role in sexual function. Estradiol test levels are also monitored for men who are undergoing testosterone replacement therapy as this form of hormone replacement can cause the estradiol blood test levels to vary out of normal ranges.
