The Galleri® test has three steps

  1. Request the test

    The Galleri test must be ordered and approved by a healthcare provider.

  2. Blood draw

    If your test request is approved, schedule your blood draw.

  3. Test results

    Results will be ready about 2 weeks after your blood draw.

Understanding your results

The provider who ordered your test will share your results with you about 2 weeks after your blood draw.


There are two possible test results

Cancer Signal Not Detected

No cancer signal was found. However, not all cancers can be detected by the Galleri test.

Next Steps
Cancer Signal Not Detected

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

There is a suspicion of cancer. The Galleri test can point to where in the body the cancer signal is coming from with high accuracy.

Next Steps
Cancer Signal Detected

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. It’s important to continue with any routine screenings your healthcare provider recommends.

How does the Galleri test find cancer?

All cells in your body release DNA into the bloodstream —but DNA from cancer cells is different from healthy cells.1

The Galleri test looks for signals present in the blood that may be associated with cancer at the time of your blood draw.

Which cancers does the Galleri test detect?

In a large-scale clinical study, the Galleri test showed the ability to detect more than 50 types of cancer — most of which lack recommended screening today.2 – 4
