Testosterone & Oestradiol

About this test

Why take this test?

  • you are a man who takes TRT and wants to check your levels of male and female hormones
  • you are a man who has breast tissue (gynaecomastia) and wants to check hormone balance
  • you are a woman who wants to investigate polycystic ovary syndrome

Testosterone is a hormone that causes male characteristics. In men, testosterone levels can impact libido, affect bone mass, body composition (such as levels of body fat and muscle mass) strength and the production of red blood cells and sperm. There are factors which can reduce a man's levels of testosterone, such as heavy alcohol consumption, liver disease and the use of AAS (anabolic androgenic steroids). Women taking oestrogen therapy may see increased testosterone levels.

Oestradiol is a steroid hormone which constitutes 80% of oestrogen in women. It is secreted by the ovaries and is responsible for the development and maintenance of the reproductive, system including fat distribution, preparing the follicles in the ovary for the release of an egg and helping to maintain bone density.

Men naturally convert some testosterone to oestradiol and it plays an important role in bone mass and sexual function. However, sometimes men can produce too much oestradiol compared with testosterone and this can result in female characteristics, especially the formation of breast tissue (gynaecomastia). 

Women also produce small amounts of testosterone. Elevated testosterone in women can cause male characteristics such as excessive hair, and is commonly associated with polycystic ovary syndrome. 

If you're worried about your homrone balance, you can quickly get answers with our simple testosterone and oestradiol test you can do at home. Our doctors will interpret your resutls and let you know whether your testosterone and oestradiol levels are within the normal ranges. 

Oestradiol blood test results below 18 pmol/L are expressed as <18 pmol/L (less than 18 pmol/L) due to the sensitivity of the testing assay.

Extended upper limit. Many testosterone tests will not measure testosterone levels above 52 nmol/L Our test will measure values up to 520 nmol/L. This is especially useful for men who are taking testosterone replacement therapy (TRT) or anabolic steroids and who expect to have supranormal levels of testosterone.

Tests Included


Testosterone is a male sex hormone which is produced in the testicles of men and, in much smaller amounts, in the ovaries of women. It is responsible for bone and muscle strength, as well as mood, energy and sexual function.

Testosterone levels decline with age and it is unusual to find naturally elevated levels in men. Low testosterone is more common than raised testosterone in the absence of supplementation.

In women, raised testosterone can result in male characteristics such as body hair, greater bulk, a deeper voice and acne - all symptoms of polycystic ovaries, a condition in which elevated testosterone is commonly seen.

Oestradiol 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 levels decline 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 excess fat (which produces oestradiol) or in relation to testosterone levels which have declined with age. Raised oestradiol in men can cause the growth of breast tissue, the loss of libido and infertility.

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