Compliance to EN ISO 22870 standard for point-of-care testing (POCT) accreditation is close to those of EN ISO 15189 in central laboratory. However, it is mandatory to master the elements which are specific to POCT. In this paper, we describe the two main processes involved to help medical biologists to achieve standard requirements, particularly in the risk assessment study. The first process concerns the deployment of a POCT device in a hospital outside laboratory and the second is the classical process of medical biology testing, outlining the steps which are different from the laboratory testing process. Furthermore, we reference, in front of each sub-process described, the different articles published in the present volume detailing specific guidelines to master them.
