ECLS Study

Early detection of Cancer of the Lung Scotland (ECLS)

Negative Blood Test

This means it is very unlikely you have lung cancer at the moment. Between 98 and 99 out of every 100 people with a negative test do not have lung cancer at that time.

If you have a negative test:
• A negative test does not mean you will never get lung cancer. It is important that you see your GP if you feel unwell in any way that could be due to lung cancer, even if this happens soon after your negative test. This includes persistent cough, coughing up blood, shortness of breath, weight loss or loss of appetite.

• If you agree, we might ask you to fill in a short survey at 1 and 3 months after your test results then 6 monthly for 1 year to ask about your health and thoughts about the blood test. The survey will take about 15 minutes to fill in, but not everybody will be asked to do this.

• It is important to remember that this test is only for lung cancer, so you should carry on having tests for other types of cancer if they are offered to you (e.g. bowel cancer test, mammograms, cervical smears.)
