WHAT IS A FEMALE HORMONE BLOOD TEST UK?

Hormones play a central role in women’s health. They regulate everything from energy levels and mood to fertility and metabolism. When hormone levels fluctuate too much or fall out of balance, it can affect your menstrual cycle, skin, and overall wellbeing.

A female hormone blood test measures key reproductive hormones to give a clearer picture of your body’s natural rhythm. It can help identify the cause of irregular periods, fertility problems, or symptoms of hormonal imbalance such as tiredness, mood changes, or weight gain.

At One Day Tests, you can easily check your hormone levels through a simple home testing kit or by visiting one of our UK clinics. Results are laboratory-reviewed and typically ready within 24 to 48 hours.

Female hormones control reproductive health and influence how the body functions day to day. The main hormones tested in women include:

• Oestrogen, which supports bone strength, menstrual cycle regulation, and mood balance.
  
  

• Progesterone, which prepares the uterus for pregnancy and maintains menstrual regularity.
  
  

• Luteinising Hormone (LH) and Follicle Stimulating Hormone (FSH), which trigger ovulation and help control the menstrual cycle.
  
  

• Prolactin, which supports breast tissue development and milk production.

• Testosterone, which helps maintain muscle strength, mood, and libido.

Hormones rise and fall naturally throughout a woman’s cycle. However, persistent imbalance can cause symptoms that impact fertility, skin health, and metabolism. A hormone blood test helps identify whether these fluctuations are within the expected range.

There are many reasons why you might consider hormone testing. Some women test as part of fertility planning, while others want to understand changes related to menopause or irregular cycles.

You may benefit from a female hormone blood test if you experience:

• Irregular or absent periods
  
  

• Difficulty conceiving
  
  

• Hot flushes or night sweats
  
  

• Acne or changes in skin texture
  
  

• Unexplained tiredness or mood swings
  
  

• Weight changes or low libido
  
  

Testing your hormone levels provides a clearer understanding of what is happening inside your body and whether further medical support may be helpful.

A female hormone blood test looks at the main hormones that control fertility, menstrual function, and overall reproductive health. The biomarkers usually include:

• Oestradiol (Oestrogen) – the primary female hormone that regulates the menstrual cycle.
  
  

• Progesterone – helps confirm ovulation and supports the uterus for pregnancy.
  
  

• LH (Luteinising Hormone) – stimulates ovulation in women and hormone production in men.
  
  

• FSH (Follicle Stimulating Hormone) – controls egg development in the ovaries.
  
  

• Prolactin – can affect ovulation and is often tested if periods are absent.
  
  

• Testosterone and SHBG (Sex Hormone Binding Globulin) – measure androgen balance and support the diagnosis of conditions such as PCOS.
  
  

• Free Androgen Index (FAI) – calculates the amount of active testosterone in the blood.
  
  

Together, these markers provide a comprehensive view of hormonal health and fertility potential.

The timing of your test can make a difference to your results. For the most accurate readings, it is generally recommended to take the test on days 2 to 5 of your menstrual cycle, when hormone levels are at their baseline.

If your periods are irregular or absent, you can take the test at any time, but interpretation may depend on your personal cycle history. Postmenopausal women can also take the test at any time since hormone levels remain relatively stable.

Your results will show the levels of each hormone in your blood and how they compare with the typical reference ranges for your age and menstrual stage.

• High FSH or LH levels may indicate reduced ovarian reserve or early menopause.
  
  

• Low oestrogen or progesterone may explain irregular periods, low mood, or fatigue.
  
  

• Elevated testosterone or FAI could point to conditions such as PCOS.
  
  

Each hormone tells a part of the story. Reviewing results with your GP or specialist can help determine if treatment, lifestyle adjustments, or further testing are needed.
