Frequently Asked Questions
The Galleri test is a multi-cancer early detection test that detects a cancer signal across more than 50 types of cancer, many of which are not commonly screened for today, through a simple blood draw. The Galleri test does not diagnose cancer and not all cancers may be detected in the blood.
The Galleri test is intended to be used in addition to, and not replace, other cancer screening tests your healthcare provider recommends.
The Galleri test looks for signals present in the blood that may be associated with cancer at the time of your blood draw. If a cancer signal is detected, the results can point to where in the body the cancer signal is coming from with high accuracy to help your healthcare provider guide next steps.
Family history is only one of many risk factors associated with cancer development. Other risk factors include eating habits, lifestyle, living or working environments, genetics, and many others.
When you submit your test request, you may ask for a pre-test consultation with a PWNHealth provider to discuss whether the test is right for you. This optional consultation is included at no additional cost.
In a clinical validation study (CCGA3*), the Galleri test detected more than 50 types of cancer across all stages.
*Circulating Cell-Free Genome Atlas (CCGA) sub-study
The Galleri test detects more than 50 types of cancers, however not all cancers may be detected in the blood. Recommended routine cancer screening tests such as colonoscopy or mammograms have been shown to reduce cancer deaths.
The Galleri test is intended to be used in addition to and not replace these tests, and can help maximize the benefits of early cancer detection. Missing recommended screening or ignoring symptoms could lead to a delayed diagnosis of cancer.
Based on data from our studies, the Galleri test has shown a low false-positive rate of 0.5% (detects a cancer signal when no cancer is present). This means that in approximately 200 people tested only 1 person would be expected to receive a false positive result.
The Galleri test development was supported by what is believed to be one of the largest clinical study programs in genomic medicine, with over 20,000 participants at more than 140 clinical study sites, including the Mayo Clinic, Dana-Farber Cancer Institute, Cleveland Clinic, Sutter Health, OHSU, Intermountain Healthcare, and U.S. Oncology Network. Please visit the Galleri clinical evidence page for more information.
The Galleri test has not been cleared or approved by the FDA. GRAIL’s clinical laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) and accredited by the College of American Pathologists (CAP). GRAIL’s clinical laboratory is regulated under CLIA to perform high-complexity testing.
The Galleri test received FDA Breakthrough Device Designation in 2019.

This means that no cancer signal was found. However, not all cancers can be detected by the Galleri test. Continue with all routine screening tests that your healthcare provider recommends. Missing routine screenings or ignoring symptoms can lead to a delayed diagnosis of cancer.
PWNHealth also offers optional post-test counseling to discuss your result, which is included in your benefit.
This means that there is a suspicion of cancer, and additional tests are needed to see if you have cancer. The PWNHealth provider who ordered your test will share this result with you and what it may mean.
When you request the test, you are given the option to enter your primary healthcare provider's contact information so your test result is automatically shared if a cancer signal is detected. If you do not have a primary healthcare provider, PWNHealth can help you find one in your area. The Galleri test can point to where in the body the cancer is coming from with high accuracy to help your primary healthcare provider guide next steps. Your primary healthcare provider should order appropriate follow-up testing to confirm if cancer is present.
This could mean that you have a cancer that is difficult to identify by the selected follow up diagnostic procedures, or that the result of the Galleri test is a false positive and that you do not have cancer. Testing was insufficient to detect cancer, including due to the cancer being located in a different part of the body. In the event that a diagnostic evaluation after a Galleri “Cancer Signal Detected” result does not confirm cancer, employees may be eligible for a complementary re-test with Galleri.
The request for a re-test must be placed by the healthcare provider managing the employee's diagnostic evaluation. The re-test must be administered within 3-6 months after the initial Galleri test. To initiate a request for a re-test, the healthcare provider managing the employee's diagnostic evaluation should contact GRAIL Medical Information at (833) 694‑2553 or medicalinformation@grailbio.com.
Galleri is a screening test that detects cancer signals in blood. When a signal is detected, the Galleri test also indicates where in the body the signal is coming from with high accuracy.
The Galleri test is not a diagnostic test. Additional tests ordered by your primary healthcare provider are needed to confirm if cancer is present which may include blood work or imaging.
The Galleri test is looking for the presence of cancer at the time your blood is drawn, but you may develop cancer in the future. The test does not measure your risk of developing cancer in the future and it does not detect all cancers.
When you request the test, you are given the option to enter your primary healthcare provider's contact information so your test result is automatically shared if a cancer signal is detected. If no cancer signal is detected, you can share the result with your provider, but we will not automatically send it.
