UK's first direct-to-consumer blood testing service. 
We've delivered over 7.5 million test results. 
We've helped over 200,000 people take control of their health. This blood test checks for unusual levels of testosterone and oestradiol, which may affect sexual libido, erectile function and fertility in men and 'male characteristics' in women such as excessive hair or help to explain abnormal periods, heavy bleeding or symptoms of menopause
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.

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.
Prepare for your Testosterone, Free 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.

Oestradiol is a steroid hormone and accounts for 80% of the oestrogen in women. 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, getting ready for fertility and helping to maintain bone density. In men, high levels of oestradiol can cause the development of breast tissue (gynaecomastia or man boobs) and affect sexual function.
Our Testosterone, Free Testosterone and Oestradiol Blood Test measures your total and calculated free testosterone, oestradiol, and SHBG level. With it, you can check for unusual levels of testosterone and oestradiol, which may affect sexual libido, erectile function, and fertility in men and male characteristics in women, such as excessive hair, or help to explain abnormal periods, heavy bleeding, or symptoms of menopause.
Testosterone is a hormone that causes male characteristics. For men, it regulates sex drive and controls bone mass, fat distribution, muscle mass, strength and the production of red blood cells and sperm. Heavy alcohol use, liver disease and steroids can cause a decrease in testosterone levels. Women taking oestrogen therapy, however, may exhibit increased testosterone levels.
