Laboratory point\u2010of\u2010care testing (POCT) has been proposed to decrease patients' length of stay (LOS).

Blood test processing was randomized into 1\u2010week inclusion periods: interventional arm (laboratory analyses performed on POCT analyzers implemented in the ED) or control arm (central laboratory). The primary endpoint was LOS of patients in the ED.
