Special instructions

Please take your sample in the morning. Take this test between days 2 and 5 of your period. It can be taken at any time if you are not having periods. HRT and the contraceptive pill can affect the results of this test, taking the test during a break from these will give more accurate results. Avoid taking a finger-prick sample from a finger used to handle hormone-gels or hormone-pessaries in the past 4 weeks. Do not take biotin supplements for 2 days prior to this test. If you are taking prescribed biotin you should discuss this with your doctor.

From the expert

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.

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) as well as affect sexual function. 

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.
