What WILL a Perimenopause
Blood Test TELL YOU?

The perimenopause is the phase a woman goes through, usually from their early to mid-40’s, as they transition towards the menopause. It is during this time that most women experience the symptoms of irregular periods, hot flushes, night sweats, brain fog, poor concentration and weight gain. 

As women transition towards the menopause, the ovaries become less response which will lead to an increase in the levels of FSH and LH. At the same time, oestradiol which is produced by the ovaries will start to decline. Our perimenopause test analyses all 3 female hormones and will indicate if you are transitioning towards the menopause.

When to take This test

The perimenopause test should be taken on day 3 of your menstrual cycle (day 1 being the first day of your period). If you are having irregular or large gaps between your periods, you can take the test at any time.

What Are the Symptoms
of the Perimenopause?

The most common symptoms of the perimenopause are:

  • Irregular periods
  • Hot flushes
  • Night sweats
  • Reduced sex drive 
  • Vaginal dryness
  • Mood swings

Often the cause of these symptoms is a result of the declining levels of oestrogen. Learn more about the perimenopause in our Guide To Menopause Symptoms.

What’s the Difference Between the Perimenopause Test and Menopause Test?

The perimenopause test measures the three key hormones that fluctuate during this phase of the menopause – it helps to identify if you are transitioning towards the menopause.

Our menopause test measures the same three hormones plus additional biomarkers key to health areas which are more at risk as you transition through the menopause and beyond.  We recommend you take the menopause test if you want a wider view of the health markers that have the greatest impact on your wellbeing during this stage of life.

Frequently asked questions

Take the guess work out of your health. Here are some of the most frequently asked questions we get asked. If you need anything else try our help section.

  • What are the stages of the menopause?

    There are 3 stages of the menopause:

    1. Perimenopause – this is a phase of time from when your hormones begin to fluctuate, and you begin to experience irregular periods until you reach menopause when your periods stop. It can last anywhere between 4 and 8 years.
    2. Menopause –used to describe the time when you have not had a period for 12 consecutive months.
    3. Post-menopause – the 24-36 months after you had your last period. Many women start to notice their symptoms reducing.
  • What is oestradiol?

    Oestradiol is the main type of oestrogen found in women. It is produced by the ovaries and has many functions, particularly within the reproductive system.

    Oestradiol levels decline with age and there is a significant drop during the menopause which is associated with many of the menopausal symptoms like hot flushes, mood swings and night sweats. In addition, reduced oestrogen along with aging increases the risk of osteoporosis and cardiovascular disease.

  • What age does the menopause occur?

    The average age of menopause – the point at which period have stopped – in the UK is 51. However, the perimenopause usually happens when a woman reaches her 40s although it can start as late as 50.

  • What lifestyle changes can I make to help manage the menopause transition?

    The reduction in oestrogen levels are the cause of many menopause symptoms and there are long-term risks of cardiovascular disease and osteoporosis after the menopause has taken place.

    There are many things you can do to help manage the symptoms of the menopause and reduce your risk of chronic disease, including:

    • Eat a healthy, balanced diet rich in fruit, vegetables, and wholegrains, low in saturated fat, salt and sugar
    • Make sure you are including good sources of calcium into your diet to help keep your bones strong and lower the risk of osteoporosis
    • Get some vitamin D. As you age and oestrogen levels drop your bones become weak which can lead to osteoporosis, so having enough vitamin D will help keep your bones strong. Vitamin D also aids the body in absorbing calcium. The best source is sunlight exposure but there are food sources like oily fish and eggs. Most adults need to take a vitamin D supplement in the winter months, but if you are going through the menopause a supplement all year round may be of benefit – but check your levels first to establish if you are low in vitamin D (we recommend >75 mol/L for optimum wellbeing).
    • Exercise regularly to maintain bone health focusing on weight bearing exercises. Exercise also helps some of the other symptoms of the perimenopause and helps reduce your risk of heart disease.
