Diagnostic Tests

This study aims to evaluate a pre-post intervention adding an early management decision at the end of the triage process to improve patient throughput. The intervention consists of adding digital checkboxes to the electronic triage system, providing nurses with formalized options for anticipated management based on patient acuity. The study compares a pre-intervention phase (May 1st to July 31st, 2026) with a post-intervention phase (May 1st to July 31st, 2027) to naturalize seasonal confounders. The primary outcome is the total Emergency Department Length of Stay (ED LOS).

To validate the NTproBNP2 Test Kit by using the test results of the predicate device as a reference. It will be demonstrated that the investigational product (NTproBNP2 Test Kit) and the predicate are equivalent. Subsequently, it will be demonstrated that the investigational product can be used in clinical testing.

To establish the reference range of the NTproBNP2 Test Kit (time-resolved immunofluorescence method) in apparently healthy Chinese population.
