Please note that to be eligible for the test, you must be 50 years or older.
Screen for multiple cancers now with the Galleri® test
Take control when it comes to cancer. The Galleri test helps you be proactive about your health.1
The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood. False positive and false negative results do occur. The Galleri test should be used in addition to cancer screening tests your healthcare provider recommends. Galleri is by prescription only.

Start screening before symptoms appear
Galleri is a screening test that looks for cancer before symptoms appear, when cancer may be easier to treat. It is important to get cancer screenings even if you feel fine.
12 of the deadliest cancers are responsible for two-thirds of cancer deaths. These cancers tend to release more DNA fragments into the bloodstream at early stages.
The Galleri test screens for many of these deadly cancers that have no recommended screening tests.
The Galleri test sensitivity for these cancers varies across cancer types and stages.
How the Galleri test works
Cancers growing in the body shed DNA into the bloodstream.1,2,3 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,4 including many without recommended screening tests.1,5 The Galleri test results provide direction to your healthcare provider and help guide the next steps for diagnosis.4
Galleri is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer.
There are two ways to request the Galleri® test
The Galleri test is available by prescription only and must be ordered by a healthcare provider. You can request the test through your healthcare provider or online through an independent telemedicine provider.
Talk to your healthcare provider
At your next wellness visit, ask your healthcare provider about Galleri. Our discussion guide can help start the conversation.
Request the test online
You can also request the Galleri test online through an independent telemedicine provider.
Our testing process
1. Request the test
The Galleri test is available by prescription only. Your healthcare provider can order the test, or you can request it through our website from an independent telemedicine provider.
2. Blood Draw
Complete your blood draw at your doctor’s office
OR
Schedule your blood draw with one of our partners. There are two options:
1. Have a trained technician come to you.
2. Visit a partner lab location near you.
3. Receive your test result
Your test result will be available about two weeks after your sample is received at the GRAIL lab.
Now you can screen for multiple cancers with Galleri.
Understanding your Galleri test result
You will receive your test result about two weeks after your blood sample is received at the GRAIL lab.
There are two possible results:
- No Cancer Signal Detected
- Cancer Signal Detected
Nearly 99% of people who use the Galleri test, will screen negative — which is exactly what you want to hear.4 Continue with routine cancer screening tests your healthcare provider recommends.
If a cancer signal is found, results can predict the tissue type or organ associated with the cancer signal and help your healthcare provider guide the next steps.4
The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood. False positive and false negative results do occur.
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 GRAIL clinical laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) and accredited by the College of American Pathologists. 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.
