Our Female Hormone Blood Test can tell you whether a hormonal imbalance or thyroid problem may be causing your symptoms, such as acne, weight gain or tiredness. You can also uncover whether a hormonal imbalance may be affecting your fertility. With our test, you can track your hormone levels and understand how they change over time. By monitoring your hormone levels, you can see whether your hormone levels are decreasing with age. If you take hormone replacement therapy (HRT), you can see if your hormone levels remain in the normal range. Female hormones are essential for a healthy female reproductive system. Other functions of female hormones include fertility, mood, and energy. Oestradiol is the main female sex hormone, which is a type of oestrogen produced in the ovaries. Other essential female hormones include follicle-stimulating hormone (FSH), luteinising hormone (LH) and progesterone. Testosterone is a crucial hormone for women because your body uses it to make oestrogen. In women, hormone levels change naturally throughout the monthly menstrual cycle. Levels of oestrogen and progesterone can decrease with age, and women can experience a rise in FSH and LH levels during menopause. A hormonal imbalance can lead to unwanted symptoms such as acne, weight gain, mood changes, tiredness, and changes to your menstrual cycle. If your hormone levels are imbalanced for a long time, you could be at higher risk of health problems such as osteoporosis. Women are much more likely to experience a thyroid condition compared to men. A thyroid condition can cause similar symptoms to a hormonal imbalance, such as feeling tired or fatigued. This blood test also checks that your thyroid is functioning normally. If you are taking the test for fertility reasons, please take on day 2 or day 3 of your cycle. If taking the test for ovulation or progesterone levels please take on day 21 of your cycle (or 7 days before the next menstrual period is due, if longer than a 28-day cycle).
