Abstract
Medical reasoning must be constructed on clinical evidence-based biology and follow a process of a priori assumptions. The introduction of a solution of point-of-care testing must result from any work involving clinicians, biologists, and administration. Several solutions of point-of-care testing allow the dosage of cardiac enzymes (CPK, myoglobin, and troponin) or BNP in less than half an hour time. The point-of-care testing saves time in obtaining the results earlier. It seems to allow timesaving on the overall care of the patient and the duration of his stay in the emergency department. By its technique and the relevance of its results, point-of-care testing is suitable for prehospital use.
