GRAL

Grail, Inc.

A healthcare company that makes the Galleri test, a single blood draw that can screen for dozens of types of cancer at once by spotting DNA fragments shed by tumors. The company was born in 2016 when DNA-sequencing firm Illumina spun it out after researchers noticed, while testing pregnant women, that tumor DNA could be found in a routine blood sample. Its name comes from the "holy grail" of medicine—a simple, non-invasive test that catches cancer early.
