CAN GP DO A BLOOD TEST FOR MENOPAUSE?

Many people wonder whether a GP can do a blood test to check for menopause, especially when symptoms start to change or become confusing. Hot flushes, cycle changes, sleep disturbance, mood swings, and brain fog can feel overwhelming, and a simple blood test may seem like the easiest way to find answers.

The truth is that GPs can arrange blood tests for menopause, but it depends on your age, symptoms, and medical background. In many cases, a diagnosis can be made without testing. In others, hormone testing is helpful or even recommended. If you want to explore your hormone levels independently, a menopause insights blood test from One Day Tests offers fast, accurate results that complement GP advice.

A GP can perform a blood test for menopause, but they do not do so for everyone. Menopause is a natural life stage, and hormone levels change in a complex and fluctuating pattern. Because of this, blood tests are not always the best indicator of where you are in the transition.

For people aged 45 and over, GPs usually diagnose menopause based on symptoms alone. If your periods have become irregular, if you are experiencing typical signs such as hot flushes or sleep disturbance, or if you have gone 12 months without a period, a GP generally does not need a blood test to confirm menopause.

However, for people younger than 45, or for those whose symptoms do not clearly match the typical pattern, a GP may recommend blood tests to understand whether menopause or another hormone issue is involved.

Understanding the criteria helps you know what to expect when you visit your GP.

For most people aged 45 and older, blood tests are not required. This is because:

• Symptoms often provide a clear picture
  
  

• Hormone levels can fluctuate widely from day to day
  
  

• A test result may appear normal even when menopause has begun
  
  

• Clinical diagnosis is usually more reliable than a single hormone reading
  
  

Common symptoms that allow a GP to diagnose menopause without blood testing include:

• Irregular or changing menstrual cycles
  
  

• Hot flushes and night sweats
  
  

• Mood changes such as irritability or mood swings
  
  

• Sleep problems
  
  

• Brain fog or difficulty concentrating
  
  

• Vaginal dryness
  
  

• Joint aches
  
  

• Lower libido
  
  

Because these symptoms are well recognised and common in menopause, a GP can base the diagnosis on them alone. This avoids unnecessary testing and speeds up access to support and treatment if needed.

Although testing is not routine for many people, there are important situations where a GP will arrange blood tests.

If You Are Between 40 And 45

If you are under 45 and experiencing symptoms such as irregular periods, hot flushes, or mood changes, a GP may use blood tests to assess whether early menopause is beginning. At this age the transition can be less predictable, and symptoms may overlap with thyroid issues, stress, or other hormonal changes. Blood testing helps clarify the picture.

If You Are Under 40 With Symptoms

If someone under 40 shows signs of menopause, a GP will nearly always do blood tests. This is because menopause before 40, known as premature ovarian insufficiency, needs medical assessment and support. Testing helps identify whether the ovaries are underactive and whether further investigations or treatment are required.

If Your Symptoms Are Unclear

Some symptoms of menopause overlap with other conditions. For example, thyroid changes, stress, and general hormone imbalance can mimic menopausal symptoms. A GP may order blood tests to check for these conditions before confirming a menopause diagnosis.

If You Are Using Certain Types Of Contraception

Some contraceptives stop periods entirely or make cycle patterns difficult to interpret. If you do not have regular periods due to contraception, a GP may decide to use hormone testing to understand what is happening in the background.

In all of these situations, blood tests can provide useful information, but they are still interpreted alongside symptoms and medical history.

When testing is appropriate, a GP may offer one or more of the following:

Follicle Stimulating Hormone

FSH levels rise when the ovaries become less responsive. High levels may suggest perimenopause or menopause, especially if symptoms are present.

Luteinising Hormone

LH can also rise during menopause, though it is usually less consistent than FSH. It provides supportive information rather than being used alone.

Additional Tests To Rule Out Other Conditions

A GP may also test for:

• Thyroid function
  
  

• Full blood count
  
  

• Iron levels
  
  

• Vitamin deficiencies
  
  

• Other hormone imbalances
  
  

These tests help rule out conditions that may present similarly to menopause.

For suspected premature ovarian insufficiency, FSH levels may be checked twice, several weeks apart, to confirm that levels remain consistently high.

Blood tests can be extremely helpful, but they do have limitations.

Hormone Levels Fluctuate

FSH and LH change from day to day, especially during perimenopause. A single reading may not give a complete picture.

They Cannot Confirm Menopause Alone

Menopause is defined by a change in menstrual pattern and symptoms, not hormone levels. Blood tests support the diagnosis but do not replace it.

Hormonal Contraception Affects Results

Some contraceptives suppress natural hormones, making FSH and LH levels unreliable for menopause assessment.

Results Do Not Predict Symptom Severity

Even if hormone levels indicate menopause, they do not reveal how mild or severe symptoms will be.

Because of these limitations, blood test results are always interpreted alongside symptoms and medical history.

A typical GP appointment for menopause concerns involves discussing:

• Symptoms
  
  

• Period changes
  
  

• Medical history
  
  

• Contraception use
  
  

• Lifestyle factors
  
  

• Family history of early menopause
  
  

If blood tests are appropriate, the GP will arrange them and explain how to prepare. Most menopause related hormone tests do not require fasting or specific cycle timing.

If testing is not required, your GP may still offer guidance on symptom relief, lifestyle adjustments, or treatment such as hormone replacement therapy. They may also refer you to a menopause specialist if further assessment is needed.

Some people prefer additional clarity through private testing, especially if their symptoms are unclear or if they want a more detailed look at their hormone patterns. A menopause blood panel can provide insight into FSH, LH, oestrogen, thyroid markers, and other biomarkers that influence the transition.

Private testing does not replace medical advice, but it can complement GP care and give you more information to support discussions about treatment and symptom management.

A GP can do a blood test for menopause, but it depends on your age, symptoms, and overall health. People over 45 usually do not need a blood test for diagnosis. For those younger than 45, or when symptoms are unclear or periods are absent due to contraception, blood tests can be a helpful tool to understand what is happening hormonally.

Hormone testing provides valuable insight, but it is only part of the picture. Your symptoms, medical history, and cycle patterns remain central to understanding where you are in the menopause transition.

A menopause insights blood test from One Day Tests offers a simple and reliable way to explore your hormone levels alongside professional medical support.
