GRAIL, Inc. is an American biotechnology company based in Menlo Park, California. It was previously a subsidiary of Illumina started as a startup seeking to develop an early cancer screening test for people who do not have symptoms. Grail was spun-out from Illumina on June 24, 2024. Their liquid biopsy was launched in June 2021 and is called the Galleri test. Promoted as groundbreaking, the test performed poorly in testing and Grail has subsequently faced discontent and legal action from investors claiming they have been misled about the test's potential.
