Understand why a test is being requested
Blood and urine tests, examination of tissue samples and genetic tests answer different questions. The investigations you need depend on the condition being assessed. Having more tests does not always mean receiving a more accurate assessment.
Before providing a sample, ask whether you need to fast, take any specific steps concerning medicines, or attend on a particular day. Preparation varies between tests. Knowing when results are expected and who will discuss them with you can also make the process easier.

-
Understand the investigation
Ask which question the test is intended to answer and how its results will be interpreted.
-
Check the preparation instructions
Follow the advice for your particular test rather than making assumptions about fasting or medicines.
-
Review your results together
A result outside the reference range is not a diagnosis on its own. Results need to be considered alongside your examination and other information.
Your Questions Answered
Do all blood tests require fasting?
No. Fasting requirements depend on the test. Ask your clinic or laboratory for preparation instructions before providing a sample.
Does a request for pathology mean I have cancer?
No. Pathology examines the characteristics of cells or tissue. Your doctor will explain why it was requested and what the result means.
Can I interpret my results online myself?
The meaning of a result can depend on your age, symptoms and other findings. A results screen provides information, but an individual interpretation requires a discussion with your doctor.
This page provides general information. The assessments or procedures appropriate for you are determined after an individual consultation and examination.
