Introducing Galleri®

Screen for more cancers with a single blood test1

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.

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.

Finally, multi-cancer early detection is possible with only a blood draw

Only 5 out of >100 known cancer types have recommended screening tests4

How the Galleri test works

The Galleri test scans a blood sample for a cancer-specific signal found on cell-free DNA (cfDNA). If detected, Galleri localizes the origin of the cancer signal with high accuracy.5

Galleri is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer. Galleri should be used in addition to healthcare provider recommended screening tests

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

Supported by robust clinical data, Galleri sets the standard for multi-cancer early detection

20,000+ individuals participated in large clinical studies1,5

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.

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.
