What if
you found cancer early enough to make a differenceTreating cancer starts
with knowing you have it
Finding cancer early is important to improve treatment outcomes and survival.1
The vast majority of cancers show no symptoms until later stages, when treatment options may be limited.2 Today, many cancers are found too late, when outcomes are often deadly.3
Multi-cancer early detection enables you to proactively test for many cancers, increasing the chances of finding cancer early.
Hear From Patients
The Galleri® multi-cancer early detection test detects a cancer signal across more than 50 types of cancer, many of which are not commonly screened for today.5 – 7 With a simple blood draw, the Galleri test provides early detection insights that help you be proactive about your health.
Have you taken the Galleri test? We would love to hear from you!
The Galleri test does not detect all cancers nor does it measure your genetic risk of developing cancer in the future. False positive and false negatives results can occur. It should be used in addition to screening tests your healthcare provider recommends.
Getting tested
The Galleri test can be included in a routine visit with your healthcare provider through a simple blood draw. Talk to your healthcare provider today about your risk for cancer, and whether the Galleri test is right for you.
The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those aged 50 or older. It is intended to be used in addition to and not replace other cancer screening tests your healthcare provider recommends.
Not all cancers can be detected by the Galleri test. Your healthcare provider will discuss appropriate follow-up testing to confirm if cancer is present.
Request the Galleri test
The process begins by requesting the test from a healthcare provider.

The prospective, return of results PATHFINDER study enrolled participants at least 50 years of age, with and without additional cancer risk and without clinical suspicion of cancer. Participants who received a “Cancer Signal Detected” result from an earlier version of the Galleri test underwent diagnostic evaluation to assess whether they had cancer. Later blood samples were reanalyzed with the Galleri test: 0.9% of participants had “Cancer Signal Detected” result. Of these, 43% had a confirmed cancer diagnosis (Positive Predictive Value, PPV). First or second Cancer Signal Origin (predicting cancer location) was accurate 88% of the time.8
In another clinical study that included participants with newly diagnosed cancer, 51.5% of these participants received a Cancer Signal Detected result (sensitivity) and a predicted Cancer Signal Origin across 50 different cancer types. The predicted Cancer Signal Origin (cancer location) was accurate 88.7% of the time. The study also included participants without cancer, 0.5% of these participants received a Cancer Signal Detected result (false positive).7,8
Important Safety Information
The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those aged 50 or older. The Galleri test does not detect all cancers and should be used in addition to routine cancer screening tests recommended by a healthcare provider. Galleri is intended to detect cancer signals and predict where in the body the cancer signal is located. Use of Galleri is not recommended in individuals who are pregnant, 21 years old or younger, or undergoing active cancer treatment.
Results should be interpreted by a healthcare provider in the context of medical history, clinical signs and symptoms. A test result of “No Cancer Signal Detected” does not rule out cancer. A test result of “Cancer Signal Detected” requires confirmatory diagnostic evaluation by medically established procedures (e.g. imaging) to confirm cancer.
If cancer is not confirmed with further testing, it could mean that cancer is not present or testing was insufficient to detect cancer, including due to the cancer being located in a different part of the body. False-positive (a cancer signal detected when cancer is not present) and false-negative (a cancer signal not detected when cancer is present) test results do occur. Rx only.
Laboratory / Test Information
GRAIL’s clinical laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) and accredited by the College of American Pathologists (CAP). The Galleri test was developed, and its performance characteristics were determined by GRAIL. The Galleri test has not been cleared or approved by the Food and Drug Administration. GRAIL’s clinical laboratory is regulated under CLIA to perform high-complexity testing. The Galleri test is intended for clinical purposes.
