Galleri: Understanding a No Cancer Signal Detected Result

There are two possible Galleri test results:
No Cancer Signal Detected
Cancer Signal Detected
In this video, we will review what a No Cancer Signal Detected result means.
If you received a No Cancer Signal Detected result, the Galleri test did not detect DNA fragments associated with cancer in your blood sample.
Nearly 99% of people who use the Galleri test will screen negative. This is exactly what you want to hear.1
In a clinical study, less than 2% of individuals with a No Cancer Signal Detected result had cancer.1,2
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. This result does not predict whether you will develop cancer in the future.
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 healthcare provider recommended screening tests.
