Were you able to show them associated cost of running lab (including QCs, PT, competency, staffing) Vs ER puts their act together and give you good specimen (basically fix pre-anlaytics before switching analytic).
We went through this and with 1) the cost we provided to run the lab and 2) improvement in TAT for Ed specimens ....we avoided going to your route...
Actually reporting mis-match historical blood type due to WBIT was big help..
