Radiology and medical imaging
Imaging methods differ in how they work and the preparation required. The method depends on the medical question. Mentioning an imaging type does not mean it is available at every facility.

Imaging and laboratory tests,
information that supports assessment.
Medical imaging and laboratory tests complement each other. Clinicians choose tests to answer a specific diagnostic question.
This guide brings together information about the two departments. Confirm the availability of a specific test and its preparation instructions before visiting.
Different tests answer different questions
Imaging shows structures inside the body, while laboratory tests analyse samples such as blood or urine. The clinician relates results to symptoms, examination and medical history.
Not every pain needs imaging, and not every concern requires a broad set of blood tests. Discuss which tests are appropriate, what they add and how they may influence care.

Laboratory and medical tests
Tests may support diagnosis, monitoring or screening according to assessment. Some need fasting or specific preparation, while others do not.
Before your test
Ask about instructions for the particular test, and disclose medicines, supplements and pregnancy or possible pregnancy. Some imaging tests require metal items to be removed, preparation or contrast material.
If fasting is requested, confirm the duration and which drinks are allowed. Do not stop medicines yourself, and tell the team if you could not follow the instructions.
Interpreting results in context
A value outside the reference range does not establish a diagnosis on its own, and a normal result does not exclude every disease. Interpretation can depend on health, age, medicines, preparation and previous results.
Discuss whether a result needs repeat testing, follow-up or another investigation. Do not change treatment based on one number without a clinical explanation.
Common questions
Must I fast for every blood test?
No. Preparation depends on the test and the laboratory’s instructions. Ask for specific guidance rather than fasting by default.
Are laboratory results enough to establish a diagnosis?
They are generally interpreted alongside symptoms, examination, medical history and imaging when appropriate.
How can I check whether a test is available?
Contact the clinics to confirm the exact test, appointment and preparation before attending.
