Out of curiosity, how many of are at EDs where LMWH is routinely given instead of UFH IN THE ED for ACS? And if you do, presumably your hospital's cardiology interventionalists are on board. Do the admitting service use Anti Xa Assays (over ACT)? And, how long is the turn-around for the Assay? Anyone has assays that are batched and take only a few hours? Thanks for the input.
