Concerned about hormonal balance, energy levels, or reproductive health? This test measures testosterone and oestradiol, two key hormones that influence muscle mass, libido, mood, and overall well-being in both men and women. It’s ideal for those assessing hormonal imbalances, fertility, or the effects of ageing on hormone levels.

We strongly recommend opting for a venous collection method to reduce the risk of sample contamination from hormone gels, creams, or from touching contaminated surfaces.

Tests with LH, FSH, or oestradiol

If you're taking your test to learn more about your fertility, take your test between days 2 and 5 of your menstrual cycle, or ideally day 3. Otherwise, for a general health check or if you're postmenopausal, you can take your test at any time.

In either case, it's important to log the date of your last period, and any other information regarding your periods or menopause status, in your MyMedichecks account right after taking your sample.

If you don't let us know the date of your last period, we'll interpret your result as though you took your test on day 3.

What's in the test?

Hormones

Oestradiol

Learn more

Oestradiol is the strongest of the three oestrogens. It's labelled a female hormone but it's made in both the ovaries and testes. It's responsible for the growth of breast tissue, the female reproductive system, and male sexual function.

In pre-menopausal women, oestradiol levels vary throughout the monthly cycle, peaking just before ovulation. Levels are lowest after menopause when the ovaries stop producing eggs. Low oestradiol levels in women can cause many symptoms associated with the menopause, including hot flushes, night sweats, and changes in mood. It can also increase the risk of osteoporosis (a condition where the bones become less dense).

In men, oestradiol levels tend to increase slightly with age as testosterone levels decline. Too much oestradiol in men can contribute to fertility problems, gynecomastia (enlarged breast tissue), and erectile dysfunction.

Testosterone

Learn more

Testosterone is a hormone that causes male characteristics. For men, it helps to regulate sex drive and has a role in controlling bone mass, fat distribution, muscle mass, strength and the production of red blood cells and sperm. Testosterone is produced in the testicles of men and, in much smaller amounts, in the ovaries of women. Testosterone levels in men naturally decline after the age of 30, although lower than normal levels can occur at any age and can cause low libido, erectile dysfunction, difficulty in gaining and maintaining muscle mass and lack of energy. Although women have much lower amounts of testosterone than men, it is important for much the same reasons, playing a role in libido, the distribution of muscle and fat and the formation of red blood cells. All laboratories will slightly differ in the reference ranges they apply because they are based on the population they are testing. The normal range is set so that 95% of men will fall into it. For greater consistency, we use the guidance from the British Society for Sexual Medicine (BSSM) which advises that low testosterone can be diagnosed when testosterone is consistently below the reference range, and that levels below 12 nmol/L could also be considered low, especially in men who also report symptoms of low testosterone or who have low levels of free testosterone.

How to prepare for your test

Prepare for your Testosterone and Oestradiol Blood Test by following these instructions. Take your sample between 6am and 10am. Take this test two to five days after the start of your period, ideally on day three. It can be taken any time if you do not have periods. Avoid taking a finger-prick sample from a finger used to apply hormone gels/pessaries/patches in the past 4 weeks. Use gloves to apply these. Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed. Hormonal contraception can affect the results of this test. Taking a break from this and waiting for your periods to restart before your blood test will give more accurate results.

    FAQs

    What is oestradiol and what does it do?

    Oestradiol is a female steroid hormone produced in women's ovaries and, to a much lesser extent, in men's testes. It accounts for 80% of the oestrogen in the female body and is responsible for developing and maintaining the reproductive system, including fat distribution, preparing the follicles in the ovary for the release of an egg, and helping maintain bone density.

    Men naturally convert some testosterone to oestradiol, and it's important for bone mass and sexual function. However, sometimes men can produce too much oestradiol compared with testosterone. This can result in female characteristics, especially the form of breast tissue (gynecomastia, moobs, or man-boobs).

    What is testosterone and what does it do?

    Testosterone is a male sex hormone produced by the testes in men's and women's ovaries and adrenal glands - but usually in smaller quantities. It governs many essential functions, such as sex drive (libido), energy levels, healthy bones, muscle mass, strength, and mood. In men, it also controls sperm production, so your levels can affect your fertility. Elevated testosterone in women can cause male characteristics, such as excessive hair, and is commonly associated with polycystic ovary syndrome. Heavy alcohol consumption, liver disease, and AAS (anabolic androgenic steroids) can reduce testosterone levels. Women taking oestrogen therapy may see increased testosterone levels.

    Does this test measure high levels of testosterone?
    Most testosterone tests set an upper detection limit of 52 nmol/L. If your result is higher than this, the lab will attempt a second measurement to get an actual reading, providing there is enough sample volume available. For this reason, we recommend taking a venous sample if you are expecting an abnormally high result (for example, if you take high doses of testosterone).

    Why have the male reference ranges for testosterone changed?

    The reference range for testosterone has been adjusted to have a lower limit of 12 nmol/L to reflect guidance from the British Society for Sexual Medicine (BSSM) 2022.

    Our medical advice regarding testosterone levels remains the same and we advise that if your total testosterone level is between the range of 8-12 nmol/L and you have symptoms of low testosterone you may be considered eligible for testosterone replacement therapy. If your testosterone level falls within this range but you have no symptoms this is considered satisfactory and no further action is required.
