multi-cancer early
detection test

The benefits of multi-cancer detection

The Galleri test detects more than 50 types of cancer through a simple blood draw.1

Early cancer detection

Early detection can help improve treatment outcomes and survival. The Galleri test detects many cancers that are not commonly screened for today, to allow for earlier treatment.1,2

Testing with ease

The Galleri test can be incorporated into a routine healthcare visit through a simple blood draw.

Actionable results

If a cancer signal is found, the results can point to where in the body the cancer is coming from with high accuracy to help your healthcare provider guide your next steps.

Who can benefit

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 is intended to be used in addition to, and not replace, other cancer screening tests your healthcare provider recommends.

Rate of new cancers by age group3

People aged 50 and above have a 13x increased risk of cancer

Talk to your healthcare provider about your risk for cancer, and whether the Galleri test is right for you.

Test order process

The process begins by requesting the test from a healthcare provider.

Important safety information

The Galleri test does not detect all cancers and should be used in addition to routine cancer screening tests. Results should be interpreted by a healthcare provider. A Cancer Signal Not Detected” result does not rule out cancer. A Cancer Signal Detected” result requires confirmatory diagnostic evaluation (e.g. imaging), and if cancer is not confirmed, it may not be present, may not be detectable by diagnostic follow-up testing or may be located in a different part of the body. False-positive and false-negative test results do occur. Rx only.
