FAQs

for Patients about the Galleri® test


Are you looking for healthcare provider FAQs?

The Galleri test is a multi-cancer early detection test that screens for a signal shared by more than 50 types of cancer, many that lack recommended screening through a simple blood test. Galleri is a screening test and does not diagnose cancer and not all cancers may be detected in the blood. Diagnostic testing is needed to confirm cancer.

The test is available by prescription only. You can request a test through your healthcare provider or on our website through an independent telemedicine provider. Download our Patient + Provider Discussion Guide to help start the conversation with your provider.

Every time you take the test, Galleri checks more than 100,000 DNA regions and over a million specific DNA sites to screen for a signal shared by multiple cancers. If a cancer signal is detected, results from the test predict the tissue type or organ associated with the cancer signal to help your healthcare provider determine next steps.

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 is intended to be used in addition to, and not replace, other cancer screening tests your healthcare provider recommends.

Use of Galleri is not recommended in individuals who are pregnant, 21 years old or younger, or undergoing active cancer treatment.

Cancer risk increases for everyone as they age regardless of family history—only 5% to 10% of cancers are inherited.

Age is the biggest risk factor for cancer. In fact, adults over age 50 are 13 times more likely to have cancer compared to people under the age of 50. Talk to your provider about your risk for cancer, and whether the Galleri test is right for you.

In a clinical study, Galleri detected a signal shared by over 50 types of cancer —including some fast-spreading and aggressive cancers responsible for approximately two-thirds of cancer deaths. Galleri is a cancer screening test, meaning it looks for cancer before symptoms appear. The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood.

Based on clinical study data, the test's sensitivity varies across different cancers (and stages). You can find sensitivity information for 24 cancer classes at: https://www.galleri.com/hcp/galleri-test-performance

A “Cancer Signal Detected” result is expected in approximately 1% or 1 out of 100 Galleri tests in people over 50 years of age.

In a recent clinical study, on average, 4 out of 10 people with a "Cancer Signal Detected" result received a cancer diagnosis with diagnostic testing, and 1 out of 200 people without cancer received a "Cancer Signal Detected" result.

(Positive Predictive Value was 43% and False Positive rate was 0.5%)

No, the Galleri test is not a genetic risk assessment. A genetic risk assessment is a one time only measurement and assesses your future risk of developing cancer. The Galleri test looks for a signal associated with active cancer at the time of your blood draw. Genetic tests may look at DNA and assess lifelong risk for cancer but cannot detect if a person currently has cancer.

Our goal is for Galleri to be a annual cancer screening test. By regularly using the Galleri test alongside recommended cancer screenings, you can increase your chance of finding cancer early.

The test is only available in the US at this time. You can request a test through your healthcare provider or on our website through an independent telemedicine provider.

No, the Galleri test is only commercially available in the US.

Galleri is available by prescription only from your healthcare provider or on our website through an independent telemedicine provider.

When you’re ready to take the Galleri test, your blood can be drawn at:

  • Your healthcare provider’s office or lab

  • Scheduled at a time and place convenient for you, visit: galleri.com/schedule
    • One of our partners’ labs

    • Your home, office, or any preferred location by a trained technician

Learn more about how your sample is processed at the GRAIL lab by watching this video.

Once you receive your sample collection kit, please do not break the quality seal on it. The collection kit should be opened by the trained technician who draws your blood sample. Make sure you store it at room temperature until your blood draw appointment. The contents are sensitive to extreme temperatures. For example, avoid storing your collection kit in the trunk of your car for long periods of time.

The trained technician who draws your blood will pack and ship your sample back to the GRAIL laboratory for processing.

No fasting or preparation is required for the Galleri test.

Approximately 1.5 tablespoons (or about 20 mL) of blood is drawn in two tubes typically from a vein in your arm.

If you no longer wish to receive your Galleri results, please contact your healthcare provider to request a cancellation. If you are not able to reach your healthcare provider or require further assistance, please contact GRAIL Customer Service by filling out a support request or calling 833−694−2553.

If your test has already been processed by GRAIL’s laboratory you will be responsible for the cost of the test.

For test orders requested through Galleri.com, refunds can only be issued if requested within 30 days of ordering and your sample has not been received at the GRAIL laboratory.

The Galleri test detected a signal often associated with cancer. This result will also include one or two predictions of the tissue type or organ associated with the cancer signal, called ​“Cancer Signal Origin.”

Results should be interpreted by a healthcare provider. This test result is not a cancer diagnosis and requires follow-up diagnostic testing which may include lab work or imaging ordered by your healthcare provider to confirm cancer. GRAIL also offers patients and providers additional support and resources if needed to help guide next steps.

False positive results do occur.

The Galleri test looked for a cancer signal in your blood sample and did not find one. This result does not completely rule out the possibility of cancer. The Galleri test does not detect a signal for all cancers and not all cancers can be detected in the blood. Continue with routine cancer screenings your healthcare provider recommends. This result does not predict whether you will develop cancer in the future.

False negative results do occur.

Adding Galleri to annual wellness visits can improve the chance of finding cancer early when it may be more treatable. Ask your healthcare provider when it’s time for your next test.

Single-cancer screening tests are recommended because they have been proven to save lives by detecting cancer early. Using Galleri in addition to recommended single-cancer screenings can increase your chances of finding cancer early, when there may be more treatment options. Galleri does not detect a signal for all cancers and not all cancers can be detected in the blood.

A Cancer Signal Detected test result is not a cancer diagnosis and requires follow-up diagnostic testing which may include lab work or imaging ordered by your healthcare provider to confirm cancer. GRAIL also offers patients and providers additional support and resources if needed to help guide next steps.

Adding Galleri to annual wellness visits can improve the chances of finding cancer early when there may be more treatment options. Ask your healthcare provider when is best to test again.

All results are automatically shared with the provider who ordered the test.

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.
