I read an article recently saying that Quest is now focusing more on ‘mainstream’ laboratory testing and buying up physical real estate while Labcorp is now gearing more towards specialty/ research based testing.
Also have seen a few posts in which people have suggested that Labcorp may be more accurate. Tough to find formal information about how they compare head to head.
I have very little experience with either. Was curious as to how others felt the two stacked up.
