The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood. False positive and false negative signal results do occur. The Galleri test should be used in addition to healthcare provider recommended screening tests.

Cancer screening today: Too little, too late

~70%

of cancer deaths are caused by cancers without recommended screening.2*

In the PATHFINDER study, Cancer Signal Origin (CSO) prediction accuracy was 88% for participants with a cancer diagnosis among study participants with "Cancer Signal Detected" test result

The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood. False positive and false negative results do occur.

Based on modeled data. Data on stage-specific incidence and 5-year survival of all invasive cancers in people aged 50–79 years diagnosed between 2006–2015. Performance of MCED test in a state-transition model (interception model) when added to usual care.
**Study demographics included 1,001 respondents, age 50+, including high-risk individuals age 35-49 (n=150). Respondents had private or commercial health insurance, Medicare, or government insurance coverage and had visited a PCP in the past two years. Data shown reflects MaxDiff relative utility values (n=1,001).

“I tell them this is a unique opportunity. We’re the only health system in this city that has availability of this blood test that can detect a shared cancer signal across 50-plus different types of cancer. It’s no cost because of a grant from our foundation. Then I ask, ‘Is this something that you’re interested in doing?’ And they always say yes.”

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.

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.
