[Guidelines for the order process of medical laboratory tests]

This document presents the requirements enumerated in the ISO 15189 standard to make reliable the formulation of a medical laboratory test order. The contents and the filling conditions of the request laboratory tests form are described, to clarify the interest of the information required. The purpose is to help to construct a specific formulation allowing the adequate realization of the laboratory tests but also to collect the needed clinical information essential to allow a relevant interpretation of the results with a goal of improvement of patient care. We present also the main forms required for special laboratory tests, particularly concerning the human genome. Finally, the criteria to be reviewed at the entry of the laboratory (contract review) during the request acceptation before its registration are enumerated.
