The Galleri test provides:
Early cancer detection
The Galleri test detects many cancers that do not have routine screening tests, helping you protect your patients’ health.2,3
Requiring only a single blood draw, the Galleri test offers a convenient way to get screened for cancer signals.
Broad and actionable
The Galleri test detects over 50 types of cancer and predicts the origin of the cancer signal with high accuracy to guide to next steps.3
The Galleri test provides two types of results
In the event that a diagnostic evaluation after a “Cancer Signal Detected” result with the Galleri test does not confirm cancer, patients may be eligible for a complimentary retest with the Galleri test.
The request for a retest must be placed by the healthcare provider managing the patient’s diagnostic evaluation. The retest must be administered within 3 – 6 months after the initial Galleri test. To initiate a request for a retest, the healthcare provider should contact their GRAIL representative or contact GRAIL Customer Service.
The Galleri test uses next-generation sequencing (NGS) and machine-learning algorithms to analyze methylation patterns of cell-free DNA (cfDNA) in the bloodstream.1
All cells — cancer and non-cancer — shed DNA into the bloodstream. cfDNA can carry cancer-specific information in its methylation patterns. DNA methylation is a process used by cells to regulate gene expression.5
In cancer, abnormal methylation patterns and the resulting changes in gene expression can contribute to tumor growth.5 Therefore, certain DNA methylation patterns can serve as a signal of cancer and provide information about the cancer signal’s origin. Through its proprietary methylation technology, the Galleri test can detect the presence of more than 50 types of cancer and predict the origin of the cancer signal with high accuracy.2,3
