Preconception health check

The health checks worth doing before trying to conceive, from bloods and immunity to medication review.

Key points

  • A preconception check typically covers rubella and varicella immunity, full blood count and ferritin, thyroid function, HbA1c where relevant, STI screening, cervical screening status, blood pressure and BMI, plus medication and supplement review including folic acid.

  • Bring your vaccination history and full medication list, including over-the-counter and herbal products; both partners benefit from the conversation.

  • Blood results return within days; any vaccinations needed (such as MMR) require completing before conception.

  • A GP or preconception specialist reviews results and converts them into specific pre-pregnancy actions, from folic acid dosing to medication switches.

About this test

Published 2026-09-27 · Next review 2027-09-27

The weeks before conception are the highest-leverage health window most people never use: starting folic acid before pregnancy prevents neural tube defects, optimising thyroid function and diabetic control before conception measurably improves outcomes, and checking rubella immunity while vaccination is still possible avoids a first-trimester scare. It suits anyone planning pregnancy in the next year, and especially those with existing conditions or long-term medications.

Private GPs and women’s health clinics offer preconception consultations within days, and NHS practice nurses cover much of the ground for those with existing conditions. Waiting lists for NHS outpatient assessment remain long in much of the UK, and many of these checks are not offered on the NHS at all unless you meet strict criteria. Private clinics can usually see you within days on a self-pay basis, with no GP referral needed in most cases.

Frequently asked

Common questions about Preconception health check.

Quick, plain-English answers to what people ask us most.

  • What does Preconception health check involve?

    Preconception health check is a structured health assessment that typically combines a consultation, examination, and a set of relevant tests chosen to screen for common health issues at this life stage or in this context. The exact components can vary between providers, so it is worth checking what is included before booking. The aim is to catch potential problems early and give you a clear picture of your current health.

  • Who is this check for, and why would someone book it?

    This kind of check is generally suited to people who want a proactive review of their health, whether due to age, family history, occupational requirements, or simply wanting reassurance. It is not usually intended to replace care for an existing diagnosed condition. A doctor can advise whether it is the right choice for your particular circumstances.

  • Do I need to prepare beforehand?

    Some elements, such as fasting blood tests, may require preparation, while others need none. You will usually receive clear instructions when you book. It is helpful to bring a list of current medications and any relevant medical history to your appointment.

  • What happens on the day?

    You will typically have a consultation with a doctor or nurse, a physical examination, and any relevant tests such as blood work, urine testing, or basic measurements like blood pressure. The appointment is usually completed in a single visit, though some results may take longer to come back. Staff will explain each step as you go.

  • How long do results take?

    Some results, such as blood pressure or basic measurements, are available immediately, while laboratory-based results usually take a few days. You will normally be given a clear timeframe and a way to discuss the results with a clinician once they are back.

  • What happens if something abnormal is found?

    If a result falls outside the expected range, the doctor will discuss what it might mean and recommend appropriate next steps, which could include repeat testing, further investigation, or referral to a specialist. Many findings turn out to need only simple lifestyle advice or monitoring. You will always have the chance to discuss the findings directly with a clinician.

  • Is this available privately, or should I use the NHS?

    Yes, this type of health check is widely available privately, usually with an appointment available within a matter of days and cost varying by provider. The NHS may offer a version of this check depending on your age and circumstances, though eligibility and waiting times vary. Many people choose the private route for convenience or a more comprehensive assessment.

  • How accurate and useful are these checks?

    The individual tests used within this kind of check are well established and reliable, though a health check is a snapshot of your health at one point in time rather than a guarantee against future illness. It is a useful tool for catching common issues early and prompting further investigation where needed. Discuss any concerns about specific results with your doctor.

  • How do I book this privately?

    You can typically book directly with a private clinic without needing a GP referral. Results are usually reviewed with you by a doctor as part of the service.
