Yes the ED is in the same building. And we have a pneumatic tube system and a fully automated Lab. But the ED docs are pushing for a ton of Point of Care testing, and we already have tons of problems with compliance with the POC that we already have. So the edict came down: either tons of POC testing or a satellite STAT Lab.
The problem with our current TAT for the ED is the very high volume of pre-analytical errors (mislabeling, short draws, clotted/hemolyzed specimens, etc). They think that if they just do all the Lab testing themselves, they will get instant results. So when told I have to do one or the other, I picked the STAT Lab. At least I can staff it with a Lab tech.
