This simple blood test measures how much oestradiol is the blood. Oestradiol is also often called E2 and is one of four different types of hormone that are produced by the ovaries. The placenta the adrenal glands, the testes, and some tissues will also produce a very small amount of oestradiol.
Maintaining the right level of oestrogen is vital for the reproductive health of an individual. If there is too little or excessive oestrogen this might give rise to medical problems, UTI’s and loss of bone strength. It might also lead to depression. Often if a doctor is concerned about puberty issues, fertility or if a patient is menopausal this test will be ordered. Here are some explanations as to why this test might be asked for, how it is performed and what the results might indicate.
An Oestradiol test can help with the diagnosis of various hormonal issues relating to fertility puberty and menopause related concerns.
