The Galleri test does not detect a signal for all cancers. 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 should be used in addition to healthcare provider recommended screening tests.

Based on a clinical study of people ages 50 to 79, around 1% are expected to receive a Cancer Signal Detected result. After diagnostic evaluation, around 40% of these people are expected to have a confirmed cancer diagnosis.
