FirstLook Lung is a simple blood test that helps doctors decide if you need a lung scan.

The test works differently based on your age because cancer risk changes as we get older.

What Your Results Mean:

What does an “Elevated” result mean?

This test does not diagnose cancer. The results (Elevated or Not Elevated) help your doctor decide if they want to get a picture of your lungs with a low-dose CT now or if they can wait.

What does a “Not Elevated” result mean?

A not elevated result means there’s a lower chance that lung cancer would be found on a scan right now. Your risk can still change over time, especially if you keep smoking. You should still get checked for lung cancer every year.

Annual Screening

To ensure your lungs stay strong and healthy, have your lungs checked every year.
