Female Hormone Panel

A five-biomarker female hormone panel measuring oestradiol, FSH, LH, prolactin, and progesterone. The timing of the blood draw within the menstrual cycle affects interpretation, and the clinic advises on optimal scheduling based on the clinical question.

Female reproductive hormones fluctuate dramatically across the menstrual cycle, and their levels at different cycle phases provide distinct clinical information. This panel captures five core markers that together map the hormonal environment governing menstrual regularity, ovulation, and reproductive health. Oestradiol (the primary oestrogen) and progesterone are produced by the ovaries and fluctuate with follicular development and the luteal phase. FSH and LH are pituitary hormones that drive the menstrual cycle — their levels and ratio provide information about ovarian reserve and can help identify patterns associated with conditions such as polycystic ovary syndrome or approaching perimenopause. Prolactin, also produced by the pituitary, is measured to rule out hyperprolactinaemia, which can disrupt menstrual regularity. The timing of the blood draw matters significantly for interpretation. Early follicular phase draws (cycle days 2-5) are typically used for baseline assessment of FSH, LH, and oestradiol, while mid-luteal phase draws (approximately cycle day 21) confirm ovulation through progesterone levels. The OneDayClinic team advises on optimal scheduling based on the individual's clinical question. This panel is suitable for women investigating irregular cycles, fertility concerns, perimenopausal symptoms, or unexplained changes in mood and energy.
