Oestrone

Oestrone is a form of oestrogen, one of the three main oestrogen hormones in the body (alongside oestradiol and oestriol). While it's less potent than oestradiol, oestrone becomes the predominant oestrogen after menopause, when it's produced mainly in fat tissue rather than the ovaries. Measuring oestrone can be useful in assessing hormonal status during and after menopause, investigating abnormal bleeding, or monitoring certain hormone-sensitive conditions. In postmenopausal women, elevated levels may be associated with increased body fat, while in premenopausal women, it helps build a complete picture of hormonal balance.
