Complements single cancer screenings

Today, routine screening exists for breast, cervical, colorectal, lung and prostate cancers.1

The Galleri test is intended to be used in addition to, and not replace, other screenings your healthcare provider recommends. 

Test order process

Follow the process with just three steps:

Ask your healthcare provider about ordering the test, they can determine if the test is right for you
Complete your blood draw
Receive your test result and next steps from your healthcare provider

Ask a healthcare provider whether the test is right for you

The Galleri test must be ordered through a healthcare provider. Your healthcare provider can discuss whether the test is right for you.

We’ll help you get the conversation started with a discussion guide that you can download and take with you.

Get a blood draw

Once your healthcare provider has ordered the Galleri test for you, a collection kit will either be given to you by your ordering provider or shipped to you. Your blood can be drawn at your provider’s clinic or one of our partner labs. 

Make sure you have the following in hand for your blood draw appointment:


Your Galleri sample collection kit

given to you by your provider or shipped to you


A completed Test Requisition Form

Receive your results and next steps

About two weeks after your blood draw, your results will be shared with you through your ordering healthcare provider.2 The Galleri test looks for signals present in the blood that may be associated with cancer at the time of your blood draw.

There are two possible results from the Galleri test:

Cancer Signal Not Detected

This means that no cancer signal was found. However, not all cancers can be detected by the Galleri test.

Next steps:

Continue with all routine screening tests that your healthcare provider recommends. Missing routine cancer screenings or ignoring symptoms could lead to a delayed diagnosis of cancer.

Cancer Signal Detected

This means that there is a suspicion of cancer. The Galleri test can point to where in the body the cancer signal is coming from to help your healthcare provider guide next steps.

Next steps:

The Galleri test does not diagnose cancer. Your healthcare provider will discuss appropriate follow-up testing to confirm if cancer is present.

This test does not measure your genetic risk of developing cancer in the future. With the Galleri multi-cancer early detection test, annual screening provides the opportunity to detect more cancers early. Your healthcare provider can help you determine when to take the Galleri test again.

False-positive and false-negative test results can occur. The Galleri test has a low false-positive rate of 0.5% (detecting a cancer signal when no cancer is present).3
