Special instructions

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

Oestradiol is a steroid hormone that accounts for 80% of the oestrogen in the female body. It is also found in men at much lower levels. It is important for both men and women to have optimal levels of oestradiol as it is essential for bone strength, libido and sexual function, and the distribution of fat. 

In women oestradiol is secreted by the ovaries, adrenal glands and the placenta in pregnancy 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. 

In men oestradiol is converted from testosterone by the action of the aromatase enzyme. Elevated oestradiol in men can cause gynaecomastia, also known as moobs or man-boobs.
