Grail's cancer screening test is used in patients, partly due to its affiliation with Illumina, the best sequencing company.

“we use Grail in our patients um when we do we don't do this in everybody for exactly the reasons you've stated you got to be able to tolerate the uh the the noise that may come of these tests that's sort of our view of aggressive cancer screening in general but but when we use it we do use Grail and that's largely based on the affiliation with alumina right which is if you've got the best sequencing company in the world that created the engine for this thing then I mean that that sort of makes sense to me”
