Go further with cancer screening

Introducing Galleri®, the first-of-its-kind multi-cancer early detection test that looks for a signal shared by 50+ types of cancer with a single blood test.1

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.

What is the Galleri test?

Galleri redefines what’s possible. Only 5 cancers have recommended screening tests.2 Using Galleri in addition to these tests can increase the chance of finding cancer early, to allow for earlier treatment.1,3

With a single blood test, Galleri screens for a signal shared by multiple cancers that would otherwise go unnoticed.1,4 If a cancer signal is detected, Galleri predicts the tissue type or organ associated with the cancer signal with 88% accuracy* to help guide follow-up diagnostic testing which may include lab work or imaging to confirm cancer.4

About Galleri
What cancers does Galleri screen for?

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

Who is Galleri for?

Age is the biggest risk factor for cancer. In fact, adults over age 50 are 13 times more likely to have cancer compared to people under the age of 50.5 Cancer risk increases for everyone as they age regardless of family history—only 5% to 10% of cancers are inherited.5,6

The Galleri test is recommended for adults with an elevated risk for cancer, such as those aged 50 or older.

  • The Galleri test is available by prescription only.

  • Use of Galleri is not recommended in individuals who are pregnant, 21 years old or younger, or undergoing active cancer treatment.

Early detection makes a difference

Around 70% of cancer deaths* are caused by cancers without recommended screenings.7

Today, there are 5 recommended cancer screening tests.2 Adding Galleri helps screen for more cancers, including cancers that do not have recommended screening.1,3

In a clinical study, Galleri approximately doubled the number of cancers detected with recommended screening.3

Why early detection matters

*Assumes screening is available for all prostate, breast, cervical, and colorectal cancer cases and 43% of lung cancer cases (based on estimated proportion of lung cancers that occur in screen-eligible individuals older than 40 years).

**For those at risk.

Galleri should be used in addition to healthcare provider recommended screening tests.

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.
