Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction
Medical laboratory services are essential to patient care and public health and therefore, have to
be available to meet the needs of all patients and the clinical personnel responsible for the care of
those patients. Such services are required to be performed according to documented policies and
procedures for examination requests, patient preparation, patient identification, collection of samples,
transportation of samples, sample storage, processing, examination of samples and reporting results,
in addition to the considerations of safety and ethics in medical laboratory work.
This document provides guidance from a number of sources that are incorporated into a set of good
laboratory practices encompassing the pre-examination processes, in a way that meets published
requirements for sample collection and handling. This document is intended to be used by individuals
and organizations engaged in the collection of samples for submission to medical laboratories for
examination, for the purpose of ensuring the quality of laboratory services and to achieve better health
outcomes for the public.
It is acknowledged that a country could have its own specific guidance or requirements applicable to
professional personnel, their activities and their responsibilities in this domain.
Each laboratory or sample collection organization should determine its level of adherence to the good
laboratory practices described in this document. Management should take the first step by setting
appropriate priorities based on patient and customer needs, the resources available, as well as local,
regional and national mandates.
This document was developed based on the Canadian Standard CSA Z316.7−12.
