The Galleri® test has three steps
Request the test
The Galleri test must be ordered and approved by a healthcare provider.
If your test request is approved, schedule your blood draw.
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.
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.
The Galleri test does not diagnose cancer. Your healthcare provider will discuss appropriate follow-up testing to confirm if cancer is present.
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.
