What is FirstLook Lung?

FirstLook Lung is a blood test that helps find people who may be at higher risk for lung cancer. It's a good option for adults who qualify for lung cancer screening but haven't been screened yet or are overdue. It's not a replacement for a low-dose CT scan, but it's a simple, non-invasive way to take that first step.

Who should get FirstLook Lung?

FirstLook Lung is for adults between the ages of 50 and 80 who have smoked at least a pack a day for 20 years, and who currently smoke or quit within the last 15 years.

How is the test done?

A nurse or technician draws a small amount of blood, just like a regular blood test at your doctor's office or a lab.

How long do results take?

Your doctor will get your results in 10 to 14 days. They will then go over the results with you.

What do the results mean?

If your result is "Elevated," it means there is a higher chance that a CT scan might find lung cancer. If it's "Not Elevated," the chance is lower, but you should still get your yearly screening.

Is FirstLook Lung FDA approved?

 No. FirstLook Lung is a lab-developed test, which means it is regulated under a program called CLIA. It has not been approved by the FDA.

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.
