GRAIL and Quest Diagnostics Provide GRAIL's Galleri® Multi-Cancer Early Detection (MCED) Test Through the Quest Diagnostics Test Ordering System

GRAIL's Galleri Test Now Directly Available to Physicians in the U.S. Through Collaboration With Quest Diagnostics, Delivering a More Streamlined Provider and Patient Experience 

MENLO PARK, Calif. and SECAUCUS, N.J., Feb. 12, 2025 /PRNewswire/ -- GRAIL, Inc. (Nasdaq: GRAL), a healthcare company whose mission is to detect cancer early when it can be cured, and Quest Diagnostics (NYSE: DGX), a leading provider of diagnostic information services, today announced the initial phase of a program to improve provider access to GRAIL's Galleri^® multi-cancer early detection (MCED) test. Providers can now order the Galleri test directly from GRAIL through the Quest Diagnostics connectivity system. The Quest Diagnostics connectivity system enables providers in the United States to order and receive reports of laboratory tests electronically through Quest's Quanum laboratory portal and more than 900 electronic health record (EHR) systems. More than 500,000 providers used the Quest connectivity system last year.

The integration will help streamline the process of ordering the Galleri test for physicians. It will also increase availability by allowing patients access to the test at any of Quest's approximately 7,400 patient access points nationwide. Patients with a test order from their physician can now go directly to Quest without needing to bring a Galleri test kit to the blood draw appointment. 

"Quest Diagnostics and GRAIL share a commitment to improving access to cancer screening and have worked productively together to enable patient access to GRAIL's Galleri test via Quest's phlebotomy network since 2021," said Mark Gardner, Senior Vice President, Molecular Genomics and Oncology for Quest Diagnostics. "Integrating GRAIL's Galleri test into the Quest connectivity system is the next step in this collaboration. We expect it to increase patient access by giving Quest's provider clients the ability to seamlessly order the test through Quest, same as they do for other blood work. This collaboration brings to life the tremendous value of Quest's ability to scale diagnostic innovation to make it accessible for all."

Cancers growing in the body shed DNA into the bloodstream. These DNA fragments act like a unique "fingerprint" of cancer. With a single blood draw, the Galleri test screens for the "fingerprint" of many of the deadliest cancers before they become symptomatic, including those with no recommended screening tests today. It can also provide doctors with information on the cancer's origin to help predict the tissue type or organ associated with the cancer signal. The Galleri test is prescription only, recommended for adults with an elevated risk for cancer, such as those age 50 or older, and is to be used in addition to recommended cancer screenings.

"We know every minute counts for busy providers, their staff and their patients, which is why we're so pleased to work with Quest to offer a seamless experience that fits into providers' existing ordering process," said Josh Ofman, MD, MSHS, President at GRAIL. "While today there are recommended screenings for five cancers, nearly 70% of deaths are caused by cancers with no recommended screening test. We believe this integration will help to make it easier to incorporate the Galleri test into routine exams to help screen for cancer before it becomes symptomatic when outcomes may be improved."

About Galleri^®
The Galleri multi-cancer early detection test is a proactive tool to screen for cancer. With a simple blood draw, the Galleri test can identify DNA shed by cancer cells, which can act as a unique "fingerprint" of cancer, to help screen for some of the deadliest cancers that don't have recommended screening today, such as pancreatic, esophageal, ovarian, liver, and others.* The Galleri test can be used to screen for cancer before a person becomes symptomatic, when cancer may be more easily treated and potentially curable. The Galleri test can indicate the origin of the cancer, giving healthcare providers a roadmap of where to explore further. The Galleri test requires a prescription from a licensed healthcare provider and should be used in addition to recommended cancer screenings such as mammography, colonoscopy, prostate-specific antigen (PSA) test, or cervical cancer screening. The Galleri test is recommended for adults with an elevated risk for cancer, such as those aged 50 or older.

Sensitivity in study participants with –
Pancreas cancer: 83.7% overall (61.9% stage I, 60.0% stage II, 85.7% stage III, 95.9% stage IV). Esophagus cancer 85.0% overall (12.5% stage I, 64.7% stage II, 94.7% stage III, 100% stage IV). Ovary cancer: 83.1% overall (50.0% stage I, 80.0% stage II, 87.1% stage III, 94.7% stage IV). Liver/bile duct cancer: 93.5% overall (100% stage I, 70.0% stage II, 100% stage III, 100% stage IV).

Important Galleri Safety Information
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.

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. The GRAIL clinical laboratory is regulated under CLIA to perform high-complexity testing. The Galleri test is intended for clinical purposes.
