Actual and potential LOS were compared for patients who were discharged after having a baseline laboratory hs\u2010cTnI test only. Total LOS incorporated time from arrival to blood sample collection, blood sampling to result availability and result availability to discharge. For potential LOS, the blood sampling to result availability time with POC use was fixed at 10 min (2\u2010min preparation and 8\u2010min test\u2010processing). The laboratory blood sampling to result availability time was from blood sample collection to result uploading on the pathology computer system. For the study, it was assumed that this was the only LOS component that would differ with POC use.
