Galleri® Multi-Cancer Early Detection Test By Grail

The Galleri multi-cancer early detection test detects more than 50 types of cancer, many of which are not commonly screened for today. With a simple blood draw, the Galleri test provides early detection insights that help you be proactive about your health.

Multi-cancer early detection enables you to proactively test for many cancers, increasing the chances of finding cancer early.


Beating cancer starts with knowing you have it

Finding cancer early is important to improve treatment outcomes and survival.

The vast majority of cancers show no symptoms until later stages, when treatment options may be limited. Today, many cancers are found too late, when outcomes are often deadly.


Finding cancer early is important

Thinking about the possibility of cancer can be overwhelming, but taking steps to find cancer early can help you feel more in control. Often, the earlier that cancer can be found, the higher the chance of better outcomes.

In studies, the Galleri test has shown the ability to detect multiple types of cancers through a single blood draw. Most of these cancers cannot be detected through current screening paradigms. When cancer signal was detected, the Galleri test localized the cancer signal with high accuracy, helping inform next steps to diagnosis.

The Galleri test is intended to be complementary to, and not a replacement of, U.S. guideline-recommended cancer screening.
