Oestradiol (blood)

Oestradiol is a steroid hormone which primarily regulates female reproductive function. This test determines the level of oestradiol in the blood.

Oestradiol is a steroid hormone that accounts for 80% of the oestrogen in the female body. It is secreted by the ovaries and is responsible for the development and maintenance of reproductive structures, including fat distribution, preparing the follicle in the ovary for the release of an egg and helping to maintain bone density. This blood test measures the level of oestradiol in your body.

Oestradiol blood test results below 44 pmol/L are expressed as <44 pmol/L (less than 44 pmol/L) due to the sensitivity of the testing assay.

Who is this blood test for

This blood test is for women who want to monitor their oestradiol level, or are looking to explain abnormal periods, heavy bleeding or symptoms of menopause.

Signs of hormonal imbalance include heavy vaginal bleeding, symptoms of menopause and unusual or early development of sex organs in both males and females.

What's included

Oestradial is a female steroid hormone which is produced in the ovaries of women and to a much lesser extent in the testes of men. It is responsible for the female reproductive system as well as the growth of breast tissue and bone thickness. Oestradiol declines with age, culminating in the menopause when the ovaries stop producing eggs.

Raised oestradiol in women can cause acne, constipation, loss of sex drive and depression as well as raising the risk of uterine and breast cancer. 

Oestradiol can also be raised in men due to too much fat (which is oestradiol producing) or in relation to testosterone levels which have declined with age. Raised oestradiol can cause the growth of breast tissue, the loss of libido and infertility in men.

Low levels of oestradiol in women can lead to osteoporosis, problems with the menstrual cycle and fertility as well as fatigue and depression.
