Out of range

It highlights where a clinician should look, but it does not by itself establish a diagnosis.

Where you'll see it: Any numerical laboratory report, usually alongside a high, low or abnormal flag.

Not necessarily. A number that sits outside the printed range is a prompt for interpretation — not a diagnosis.

• A single result rarely gives the full picture — clinicians interpret it alongside your symptoms.
• Your medical history, medications and other blood tests all shape the meaning of one value.
• Small movements just outside the reference range are common and often not concerning.
• Repeat testing over time is frequently more useful than any single number.

• Check the units and the range printed on your own report.
• Ask the requesting service whether the test should be repeated and when.
• Mention any symptoms, recent illness or new medicines — they can affect results.

One result rarely tells the whole story. Clinicians look at your symptoms, medical history, medications and other tests together — and a single value that sits slightly outside the reference range is often normal for you. Repeat testing over time is frequently more useful than any one number. Medipher helps you understand what a result means in plain English, but it cannot diagnose medical conditions or replace advice from a doctor, nurse or pharmacist.

Speak with your GP or another healthcare professional if:

• You've been asked to repeat the test.
• You're experiencing new or worsening symptoms.
• Your clinician has flagged the result as needing follow-up.
• You don't understand your results or feel unsure what to do next.

If you have severe symptoms — chest pain, severe breathlessness, fainting, heavy bleeding or feel very unwell — seek urgent help. If this is a medical emergency, call your local emergency number immediately. Medipher is designed to help explain medical information and is not an emergency service.
