A useful health check is not the largest package of tests. It is a personalised prevention review based on age, sex, family history, symptoms, pregnancy context, medicines and established risk. Every test should have a reason and a plan for interpreting the result.
Build the check around risk
Blood pressure, tobacco exposure, diabetes and cardiovascular risk are relevant for many adults, while the timing of cancer screening and other tests varies. Earlier or more frequent assessment can be appropriate for family history or known conditions.
Bring previous results so the clinician can review trends. Repeating a normal test too frequently can create cost and false-positive findings without improving health.
- Blood pressure
- Glucose risk
- Cholesterol and cardiovascular risk
- Tobacco and alcohol
- Family history
- Age-appropriate screening
Screening is for people without symptoms
Screening looks for disease before symptoms arise. A person with symptoms needs diagnostic evaluation, which may use different tests and urgency. Ask whether the proposed test is screening or diagnosis.
Before a screening test, understand who benefits, possible false positives and negatives, how often it is recommended and what follows an abnormal result.
- Evidence for the target age or risk group
- Benefits and limitations
- False-positive possibility
- Confirmatory pathway
- Screening interval
- Informed choice
Prevention beyond blood tests
Vaccination, oral health, vision, hearing, movement, nutrition, sleep and mental wellbeing may matter more than an exhaustive laboratory panel. Injury prevention and reproductive or sexual health should be discussed according to age and context.
A health check is also an opportunity to review medicines, including supplements, and remove duplication or unsafe use with clinical guidance.
- Vaccination review
- Mental wellbeing
- Physical activity
- Sleep
- Oral and sensory health
- Medicine reconciliation
Understanding an abnormal result
A value outside a reference range is not automatically disease. Reference intervals include most, not all, healthy people, and temporary factors can affect results. Conversely, a value inside the range does not rule out every condition.
Ask whether the result needs repeating, confirmatory testing, treatment or observation. Avoid changing medicines or starting supplements from one isolated number.
