Cancer Screening
Now there’s a proactive tool to screen for cancer
Galleri® is a multi-cancer early detection test that screens for many of the deadliest cancers before they become symptomatic, including those with no recommended screening tests today.
Cancers growing in the body shed DNA into the bloodstream, and the DNA fragments can act like a unique "fingerprint" of cancer.

Screen for cancer before symptoms appear
Aggressive cancers can develop quickly and without symptoms. Cancers growing in the body shed DNA into the bloodstream, the DNA fragments can act like a unique "fingerprint" of cancer. The Galleri test may be able to detect such a “fingerprint” before a clinical diagnosis through conventional means.
FAQs
-
Galleri is a multi-cancer early detection test that can be taken as a simple annual blood test and screens for many of the deadliest cancers before they become symptomatic. The Galleri test gives you more control when it comes to cancer.

Cancers growing in the body shed DNA into the bloodstream. Although there are many types of cancer, the DNA fragments can act like a unique “fingerprint” of cancer. This Galleri test screens for many of the deadliest cancers before they become symptomatic, including those without recommended screening tests. When there is a Cancer Signal Detected, the results also provide predicted Cancer Signal Origin* to help your healthcare provider determine the next steps for diagnosis.
-
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.
Use of Galleri is not recommended in individuals who are pregnant, 21 years old or younger, or undergoing active cancer treatment.

In a clinical study, Galleri detected a signal shared by over 50 types of cancer —including some fast-spreading and aggressive cancers responsible for approximately two-thirds of cancer deaths. Galleri is a cancer screening test, meaning it looks for cancer before symptoms appear. The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood.

Nearly 99% of people who take the Galleri test will receive a No Cancer Signal Detected result. A Cancer Signal Detected result is expected in approximately 1% of Galleri tests in people over 50 years of age. After diagnostic evaluation, around 40% of these people are expected to have a confirmed cancer diagnosis.
Some of the ways we measure test accuracy is with positive predictive value (PPV) and a false positive rate. A PPV is the probability that a person with a Cancer Signal Detected test result has cancer. In a recent study the PPV was 43.1% for study participants with a Cancer Signal Detected result who were diagnosed with cancer. The false positive rate was 0.5% for participants without cancer.
