PATIENT INFORMATION
Why have I been asked for a chest X-ray or lung test?
When these tests may be useful
A chest X-ray or lung-function test may be useful when there is a clinical reason. Examples include significant breathing symptoms, known lung disease, or a procedure where the result could change management.
Routine chest X-rays are not recommended for every surgical patient in many international guidelines.
India-specific ISA guidance for routine investigation in ASA I-II patients differs from NICE in some age and surgery categories. The exact test list may therefore legitimately vary between settings.
What the tests involve
- Chest X-ray: a quick picture of the chest using a small dose of radiation. Tell staff if you might be pregnant.
- Lung-function test (spirometry): you breathe in deeply and blow hard into a tube connected to a machine. The lab may give instructions about using inhalers before the test. Follow those instructions.
Bring previous reports
If you have had a recent chest X-ray, CT scan or lung test, bring the report and images if available. This may avoid a repeat.
An abnormal result needs interpretation in your clinical context. Do not decide whether surgery is safe, or change treatment, solely from information on this website.
