This app provides short, quick, practical guidance on tests needed for presenting complaints in the emergency department. This app is aimed at nurses and students who want to get appropriate tests ordered before the doctor assesses the patient. Blood tests and point of care tests are listed and briefly explained giving you rapid, straightforward guidance when time is precious. Although the tests are chosen and described by doctors the app is designed and coded by an actual A and E nurse who understands the workflow of a busy emergency department.
