Called claiming to be collecting for a bill for blood work at NW Labs.  Two problems:  No one here has had blood work of *any* kind done either by them or anyone else for several years, and we've never had anything done my that entity in any event.  Ergo, either they have sloppy and/or erroneous records (possible) or they've become one of the many outfits that has adopted the business model of "bill anyone, take the money if they pay."
