Why is early detection important?
The Galleri test allows you to screen for more cancers when used in addition to single cancer screening tests.2,3 The Galleri test identifies DNA in the bloodstream shed by cancer cells and does not predict your future genetic risk for cancer.
Only 5 cancers have have recommended screening tests:
breast, cervical, colorectal, lung (for those at risk), cervical and prostate.2
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.
Who is eligible?
If you are a first responder, you may request the Galleri test at a reduced cost of $649 using the Galleri Key provided to you.
The Galleri test is available by prescription only. The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those aged 50 or older.

What is the Galleri test?
Galleri is a multi-cancer early detection (MCED) test that looks for a signal shared by more than 50 types of cancer.1 If a cancer signal is detected, Galleri can predict the tissue type or organ associated with the signal to help healthcare providers determine next steps.
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. Galleri is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer.
Our testing process
Request the test
The Galleri test is available by prescription only. You can request the test through our website from an independent telemedicine provider.
Receive a collection kit
If the independent telemedicine physician confirms you are eligible and orders your test, you can schedule a blood draw at one of GRAIL’s blood draw partners and we will ship you a Galleri collection kit for your appointment.
Provide your sample
The trained technician that draws your blood sample will ship the kit back to the GRAIL lab.
Receive your results
An independent telemedicine provider will reach out when your results are ready — about 2 weeks after your blood draw. Your test result will be shared with you by an independent telemedicine provider.
Understanding your results
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
Galleri looks for a signal shared by more than 50 cancer types.1 You will not receive a list of the 50+ types of cancer and a result for each one.
If Galleri detects a cancer signal, your result will include Cancer Signal Origin predictions which provides information about the tissue type or organ associated with the Cancer Signal to help healthcare providers determine next steps.
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.
A Galleri result of No Cancer Signal Detected does not rule out cancer.
Galleri is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer.
Frequently Asked Questions

Cancers growing in the body shed DNA into the bloodstream. Although there are many types of cancer, the DNA fragments act like a unique fingerprint of cancer.1,4,5 The Galleri test can screen for many aggressive cancers before they become symptomatic,3 including those with no recommended screening tests.1,2,6 With this unique “fingerprint” of cancer, the Galleri test helps to provide direction to your healthcare provider on the cancer’s origin and the next steps in diagnosis.3,7

More than 1 in 3 people will develop cancer in their lifetime.8 People over the age of 50 are 13 times more likely to have cancer than those under 50.9 Cancer risk increases for everyone as they age, regardless of family history — only 5% to 10% of cancers are inherited.9,10
For firefighters, occupational cancer is the #1 cause of line-of-duty deaths.11
The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those age 50 or older.
Talk to your provider about your risk for cancer and whether the Galleri test is right for you. The Galleri test is available by prescription only.
No. A genetic or hereditary risk assessment is a one-time-only measurement and assesses your future risk of developing cancer.10 The Galleri test is a point-in-time test that identifies DNA in the bloodstream shed by active cancer cells.1
In a clinical study, the Galleri test detected a signal shared by more than 50 types of cancer — including some fast-spreading and aggressive cancers responsible for approximately two-thirds of cancer deaths.1,6 Galleri is a cancer screening test, meaning it looks for cancer before symptoms appear.3
See the list of cancer types study participants had when a cancer signal was detected.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.
Nearly 99% of people (ages 50-79) who take the Galleri test will receive a No Cancer Signal Detected result.3 In other words, approximately 1% are expected to receive a Cancer Signal Detected result. After diagnostic evaluation, around 62% of people with a Cancer Signal Detected result are expected to have a confirmed cancer diagnosis.12*
Some of the ways we measure test accuracy are with positive predictive value (PPV) and a false positive rate. A PPV is the probability that a person with a Cancer Signal Detected test result has cancer (i.e., 62%). The false positive rate was 0.4% for participants without cancer.12*
*Based on the first ~25,000 participants with 1 year of follow-up.

Watch the Clinical Laboratory Virtual Tour video to learn more about how your sample is processed at the GRAIL lab.
First, do not break the quality seal on your sample collection kit. The 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 to the GRAIL laboratory for processing.
No, fasting is not required for the Galleri test.
Approximately 1.5 tablespoons (or about 20 mL) of blood in two tubes is typically drawn from a vein in your arm.
If you no longer wish to receive your Galleri test result, please contact GRAIL Customer Service by completing the online form on the Contact Us web page or by calling (833) 694‑2553
You will be responsible for the cost if the GRAIL laboratory has already processed your test.
Typically, you can expect to receive your test result about 2-3 weeks after your sample arrives at the GRAIL lab. In certain cases, results may take up to 4 weeks.
If you have not received your result within 2 weeks, GRAIL will notify you via email (sent to your email address if one was provided on your Test Requisition Form).
It is important to understand that the timing of your test result does not indicate or predict the outcome of the test, nor does it impact the accuracy of the final result.
If you provide your email when ordering the test, your result will be emailed to you. You can also request your test result by contacting GRAIL Customer Service via the Contact Us online form or by calling (833) 694‑2553.
The Galleri test detected DNA methylation patterns often associated with cancer in your blood sample. About 1 out of every 100 tests has a Cancer Signal Detected result.3
This result will also include a prediction of the tissue type or organ associated with the cancer signal, called a Cancer Signal Origin (CSO). The CSO helps your doctor determine the next steps for diagnosis.1
A healthcare provider should interpret the results. The 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 the next steps.
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.

This result does not completely rule out the possibility of cancer, and you should continue with other cancer screenings your provider recommends. While the Galleri test is a powerful tool, it cannot detect a signal for all cancers and not all cancers can be detected in the blood. Some cancers shed little or no DNA into the bloodstream, which makes them unlikely to be detected through a blood test (e.g., brain, skin, and early breast and prostate cancers).13 False positive and false negative results do occur. The Galleri test identifies DNA in the bloodstream shed by cancer cells and does not predict future genetic risk for cancer.
The Galleri test can be taken as an annual blood test. Adding the Galleri test to yearly wellness visits can improve your chance of finding a cancer signal early, when more treatment options may be available.14 Ask your healthcare provider when it is best to test again.
The Galleri test is intended to be used in addition to — and not replace — other cancer screening tests your healthcare provider recommends. Single-cancer screening tests are recommended because they have been proven to save lives by detecting cancer early. Adding the Galleri test to annual wellness visits can improve your chance of finding a cancer signal early, when more treatment options may be available.14

The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those age 50 or older. The test does not detect all cancers and should be used in addition to routine cancer screening tests recommended by a healthcare provider. The Galleri test is intended to detect cancer signals and predict where in the body the cancer signal is located. Use of the test 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
