I didn't see the ad, either, but I know this story well.
Companies offering in-house pathology set-up usually consist of slick entrepreneurs who have some pathology lab experience, having worked as techs and such. No M.D.'s. Used-car salesmen with a weak lab background.
For a fee, they'll create space in a clinician's office building basement and put in some crummy machines. Then they'll approach the local pathologist talent with a take-it-or-leave-it offer to sign out cases. I expect the latter is the best part of their job.
Actually, this IS helpful for clinicians new to the game, because generally their pathology lab knowledge is non-existent and they intend to keep it that way. Plus, approaching formerly treasured colleagues and telling them you are screwing them can be unpleasant, and it's nice to let your paid ax-men break the ice.
The company gets a cut of profits for a specified time after the basement lab is up and running, usually a year or so. By then, the clinicians realize the installation was half-as$ed and problem-ridden, but it is too late.
