The Galleri test screens for multiple cancers

The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood.

How does the Galleri test work?

Cancers growing in the body shed DNA into the bloodstream.1,2,3 Although there are many types of cancer, the DNA fragments can act like a unique “fingerprint” of cancer. The Galleri test screens for many of the deadliest cancers before they become symptomatic, including those without recommended screening tests.1,4 The test results provide a predicted Cancer Signal Origin* to help your healthcare provider determine the next steps for diagnosis.5

Screen for cancer before symptoms appear

Every time you take the test, Galleri screens more than hundreds of thousands of DNA sites in the most informative DNA regions to screen for many of the deadliest cancers before they become symptomatic.1,2,5 Cancer can develop at any time. The Galleri is a point-in-time test that identifies DNA shed by cancer cells and screens for cancer at the time of testing. 
 

Galleri is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer. The Galleri test is not a genetic risk assessment and does not predict future genetic risk for cancer.

Understanding your results

You will receive your test result about two weeks after your blood sample is received at the GRAIL lab.

There are two possible results:

— No Cancer Signal Detected
— Cancer Signal Detected

Nearly 99% of people who use the Galleri test will screen negative — which is exactly what you want to hear.5 Continue with routine cancer screening tests your healthcare provider recommends.

If a cancer signal is found, results also can predict the tissue type or organ associated with the cancer signal. This vital information can help guide your healthcare provider with the next steps.5

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. Galleri is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer.

The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those age 50 or older. The test does not detect all cancers and should be used in addition to routine cancer screening tests recommended by a healthcare provider. The Galleri test is intended to detect cancer signals and predict where in the body the cancer signal is located. Use of the test 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.

The GRAIL clinical laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) and accredited by the College of American Pathologists. 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. The GRAIL clinical laboratory is regulated under CLIA to perform high-complexity testing. The Galleri test is intended for clinical purposes.
