Women’s Health Check: Blood Tests, Hormones & What to Consider

Feeling tired, noticing changes in your periods or planning a pregnancy? A useful health check starts with understanding your concerns and choosing investigations that can help answer them.

This guide explains what different tests can tell you, when they may be useful and how to explore women’s health testing at MDC on Baker Street, London.

What is a women’s health check?

A women’s health check is an assessment of your health, concerns and relevant risks. It may involve discussing your symptoms, menstrual history, lifestyle, medicines and previous results, followed by measurements, examination or selected tests where appropriate.

The term is used differently by different providers. A blood-test package does not necessarily include a consultation, examination, ultrasound or follow-up appointment. Before booking, ask exactly what is included and who will help you interpret the results.

Investigating symptoms

Tests chosen to explore a concern, such as persistent tiredness, heavy periods or an irregular cycle.

Monitoring health

Checks used to follow an existing condition or monitor the effects of prescribed treatment.

Planning ahead

A review of relevant risks, pregnancy plans or eligibility for established screening programmes.

Is there a “full female health check”?

There is no standard test that checks everything. Even an extensive blood panel cannot rule out every illness or explain every symptom. The useful question is: “What are we trying to find out, and how would the result change my care?”

What blood tests might be included?

These are examples of investigations that may be considered. They are not a checklist for every woman or a list of tests included in every MDC package.[1]

Possible tests and the questions they can help answer
Possible testWhat it assessesWhen it may be considered
Full blood countRed cells, white cells and platelets; can identify anaemia.Heavy periods, persistent fatigue or suspected blood abnormalities.
Ferritin and iron studiesIron stores and other aspects of iron status.Suspected iron deficiency or clarification of abnormal blood-count findings.
Vitamin B12 and folateLevels relevant to blood-cell production and, for B12, nerve health.Symptoms or risk factors suggesting deficiency.
Vitamin DVitamin D status.Suspected deficiency, very high risk or another clinical indication.
Thyroid functionTSH, with FT4 and sometimes FT3 depending on the clinical question.Symptoms suggesting an underactive or overactive thyroid.
HbA1c or glucoseBlood sugar regulation.Diabetes symptoms, relevant risk factors or monitoring.
Cholesterol profileBlood fats used in cardiovascular risk assessment.Assessment informed by age, blood pressure, family history and other risks.
Kidney or liver blood testsMarkers that help assess organ function or injury.Relevant symptoms, existing conditions or medicine monitoring.
Selected reproductive hormonesHormonal information relevant to cycles and ovulation.Irregular periods or a defined fertility investigation.
AMHAn ovarian reserve marker used in fertility care.Selected fertility-treatment planning; not a prediction of natural pregnancy.

Explore MDC’s private blood testing options once you know which question you want the test to answer.

Which tests may help investigate tiredness?

Persistent tiredness can have several causes. Sleep problems, stress, medicines and other health conditions all matter. Blood tests may help investigate anaemia, diabetes or thyroid disease, but they do not replace a conversation about how you feel and how long symptoms have lasted.[2]

Iron and ferritin

Iron deficiency may be relevant when there is blood loss or another reason to suspect low iron. Ferritin helps assess stored iron, while a full blood count checks for anaemia. Results need to be interpreted together with your symptoms and history.

For heavy menstrual bleeding, NICE recommends a full blood count. It does not recommend ferritin or female hormone testing routinely for everyone with heavy periods. Additional investigations depend on the findings and the wider clinical picture. [3]

Vitamin B12 and folate

Testing may help when deficiency is suspected, for example because of symptoms, dietary concerns or problems absorbing nutrients. Blood results are considered alongside symptoms; a number on its own does not always settle the diagnosis. New tingling, numbness or balance problems deserve medical assessment. [4]

Vitamin D

Vitamin D testing is not routinely needed for every woman who feels tired. NICE recommends testing when there are symptoms of deficiency, very high risk or another clinical reason. Advice about supplements and a decision to measure blood levels are separate matters. [5]

Thyroid testing: do you need TSH, FT4 and FT3?

For most adults with suspected thyroid dysfunction, TSH is the starting test. FT4 and sometimes FT3 help clarify abnormal findings. Different testing is needed in some situations, such as suspected pituitary disease. Thyroid antibodies answer a separate question about possible autoimmune disease. [6]

A broad thyroid panel is therefore not automatically necessary. The choice depends on symptoms, previous results and the reason for testing. You can view MDC’s thyroid testing profiles and ask which matches the investigation recommended for you.

Female hormone testing: why timing matters

Hormone results need context. The same value can mean different things depending on your menstrual cycle, age and use of hormonal contraception or treatment. Tell the clinician what you take and when your last period began.

FSH and LH may be used when investigating irregular cycles. Progesterone used to assess ovulation is measured later in the cycle: day 21 applies to a 28-day cycle, not every cycle. Longer or irregular cycles require an individual timing plan. [7]

Before booking: confirm the correct day for each hormone test. A package containing several hormones may require samples at different times. Do not stop contraception or prescribed treatment simply to obtain a blood result without advice.

What if my periods are irregular?

If pregnancy is possible, consider a pregnancy test first. Assessment may explore contraception, weight changes, stress, exercise, thyroid symptoms and signs of an ovulation disorder. Blood tests are chosen from this history; some people also need examination or imaging. [8]

Heavy bleeding and irregular timing are different concerns. A reproductive hormone panel is not automatically the correct investigation for heavy periods.

Can a blood test diagnose PCOS?

No single blood test can diagnose PCOS. You may also see its newer name, polyendocrine metabolic ovarian syndrome (PMOS), in current health information. [9]

Assessment considers cycle patterns, signs or blood-test evidence of raised androgens, and ovarian findings where needed, while excluding other explanations. In adults, ultrasound or appropriately interpreted AMH may contribute to the diagnostic pathway; neither is automatically required in every case.

An AMH result or an LH-to-FSH ratio alone is not a diagnosis. Adolescents require a different assessment approach. A package labelled “PCOS testing” provides information for assessment, rather than a stand-alone yes-or-no answer. [10]

Fertility testing and AMH: what can they tell you?

Fertility assessment may involve ovulation testing, investigation of the womb or fallopian tubes, and semen analysis where relevant. A female hormone panel cannot assess all these factors. [11]

AMH can inform treatment

AMH helps predict ovarian response to stimulation and supports discussions about assisted conception.

AMH cannot predict natural pregnancy

NICE advises against using AMH to predict whether someone will conceive spontaneously.

Interpret the whole picture

Age, cycle history, previous pregnancies and other findings remain important. AMH is not an overall fertility score.

Routine prolactin and thyroid testing are not recommended for every fertility concern; each needs an appropriate clinical indication. [7]

Seek assessment after a year of trying without pregnancy, or sooner if you are 36 or over or have a known concern. Irregular or absent periods are a reason to seek advice earlier. [11]

What should I discuss before trying for a baby?

A pre-conception review is broader than blood testing. Discuss existing conditions, prescribed medicines, vaccination history, cervical screening if due and STI testing where relevant. Do not stop prescribed medicines without advice. [12]

The NHS recommends 400 micrograms of folic acid daily when trying to conceive and through the first 12 weeks of pregnancy. Some people need a prescribed higher dose. You do not need to wait for a folate blood test before following this advice. [13]

Ask which, if any, blood tests would change your preparation or care. A large hormone or vitamin panel is not a universal requirement before pregnancy.

Do women need different checks at different ages?

Health priorities change over time, but birthdays do not create an automatic need for a fixed blood panel.

  • During the reproductive years: periods, contraception, symptoms and pregnancy plans help guide assessment.
  • Around menopause: discuss cycle changes, hot flushes, sleep, mood and their effect on daily life.
  • Later in life: review existing conditions, medicines, cardiovascular and bone-health risks, and relevant screening invitations.

Menopause does not usually require a hormone panel. In otherwise healthy people aged 45 or over with typical symptoms, NICE generally recommends diagnosis from symptoms and menstrual history. Selected testing may be appropriate at younger ages or when the diagnosis is uncertain. [14]

Private blood tests and NHS screening are different

National screening programmes, including cervical, breast and bowel screening, are offered to defined groups following assessment of benefits and harms. They are different from investigating a symptom or purchasing a private blood panel.

A private women’s health blood test does not replace screening invitations or assessment of new symptoms. Normal blood results do not rule out every disease. Discuss symptoms even if your recent screening or blood tests were normal. [15]

Which MDC pathway could I discuss?

Start with your reason for testing. The options below are starting points for a discussion, not individual recommendations. MDC’s Women’s Health page lists its current hormone and fertility packages.

Match the investigation to your concern
Reason for testingQuestion to clarify firstMDC option to explore
Persistent tiredness or general health concernsWhich findings in my history suggest a specific test? Private blood testing rather than automatically choosing a fertility package.
Periods or hormone concernsWhich hormones are relevant, and when should they be measured?Female Hormone Profile or Hormone Clarity Profile.
A defined fertility investigationIs the question about ovulation, ovarian reserve or another factor?Female Fertility Profile or Basic Female Profile.
Preparing for pregnancy or fertility treatmentWhich investigations has my clinician recommended?Discuss the contents of Optimise & Prepare.
Several established investigation needsWill a broader package answer useful questions or duplicate existing tests?Discuss Advanced Care and whether its additional components are appropriate.
Fertility concerns involving both partnersWhat assessment does each partner need?Ask about the Couples’ Fertility Assessment listed on the Women’s Health page.

Despite its name, the Basic Female Profile is listed as a fertility-oriented package, including ovarian reserve markers, thyroid testing and a full blood count. It should not be assumed to be a universal general-health check.

Confirm the exact tests, preparation, price and follow-up arrangements before booking. Ask whether a consultation is included or arranged separately, and whether cycle timing requires more than one visit.

When should I speak to a clinician first?

Arrange assessment for persistent unexplained tiredness, periods that become irregular, heavy bleeding that affects your life or ongoing pelvic symptoms. Booking more tests yourself may delay finding the right explanation.

Bleeding after menopause should always be checked, even if it happens only once or is a small amount. Do not wait for a hormone panel. [16]

Private women’s health testing in London

Marylebone Diagnostic Centre
73 Baker Street, London W1U 6RD

To explore testing, start with your main concern: a change in your periods, persistent tiredness, a clinician’s test request or a fertility question. Bring previous results and a list of medicines and supplements where possible.

MDC offers private blood testing without a GP referral. This provides direct access to testing, while symptoms and results may still require clinical assessment.

Quick answers

What blood tests should every woman have?

There is no universal list. Symptoms, medical history, medicines and relevant risks determine whether blood tests are useful and which ones to choose.

What does a private women’s health check include?

This varies between providers and packages. Confirm whether you are booking blood tests alone or an assessment that also includes a consultation, examination and follow-up.

Can a full female health check rule out everything?

No. Blood tests answer specific questions. A normal panel cannot rule out every condition, so persistent or new symptoms still need attention.

Can female hormone tests be taken on any day?

Not all results are interpreted in the same way throughout the cycle. Confirm timing before booking, particularly when testing progesterone to assess ovulation.

Can blood tests confirm PCOS on their own?

No. Blood results contribute to a wider assessment of symptoms, cycles and other possible causes. A single raised hormone or AMH result is insufficient.

Do I need fertility blood tests before trying for a baby?

Not automatically. A pre-conception discussion can establish whether tests would be useful and cover medicines, vaccination history and folic acid.

Do I need a GP referral for MDC blood tests?

MDC’s private blood testing service accepts direct bookings without a GP referral. Confirm the test, preparation and arrangements for interpreting results before attending.

Where can I arrange women’s health testing in London?
