A blood test can provide useful information about different aspects of your health. But when a report arrives filled with abbreviations, figures and reference ranges, it is natural to have questions.
Start with the reason for the test
Understanding why a test was requested can help put the result into context. Your clinician can explain what they were looking for and how the findings relate to your symptoms, history and overall health.
What do reference ranges mean?
Laboratories often show a reference range beside a result. These ranges help clinicians interpret findings, but they are not a diagnosis on their own. A result outside a range does not automatically mean something is wrong, and a result inside a range does not always rule out a health concern.
Questions you can take to your appointment
- What was the purpose of this test?
- Which results are important in my situation?
- Do any results need to be repeated or followed up?
- Could medicines, recent illness or other factors affect the result?
- What should I do next, if anything?
Look at the bigger picture
Test results are most useful when considered alongside your medical history, symptoms, examination and other relevant information. Avoid changing medication or starting treatment based on a report without discussing it with your healthcare professional.
