Female Hormone Test

An eight-biomarker female hormone panel measuring FSH, LH, oestradiol, progesterone, testosterone, SHBG, prolactin, and free androgen index. Provides a comprehensive picture of the reproductive endocrine axis with results in 24 hours.

Female hormonal health involves a finely balanced interplay between the pituitary gland and the ovaries, with each marker influencing the others in a cyclical pattern that varies across the menstrual month. This panel captures the key players: the pituitary hormones (FSH and LH) that orchestrate follicular development and ovulation, the ovarian outputs (oestradiol and progesterone) that reflect cycle phase and function, and the androgenic markers (testosterone, SHBG, free androgen index) that can signal conditions such as polycystic ovary syndrome when elevated. Prolactin is included because hyperprolactinaemia is a common and frequently missed cause of menstrual irregularity, anovulation, and galactorrhoea. The free androgen index — calculated from testosterone and SHBG — is the most sensitive measure of androgen excess in women and is more diagnostically useful than total testosterone alone for conditions such as PCOS. Blood should ideally be drawn on days 2 to 5 of the menstrual cycle for the most clinically meaningful hormonal baseline. Hormonal contraception may alter several of these markers, so timing and context are important for interpretation. Results are delivered within 24 hours, with express same-day availability at the Great Portland Street clinic.
