Medical laboratories - Requirements for quality and competence


TCVN ISO 15189:2014ISO 15189:2014 is completely equivalent to ISO 15189:2012;
TCVN ISO 15189:2014 replaces TCVN 7782:2008;
TCVN ISO 15189:2014 is compiled by the Technical Committee for standards TCVN/TC 176, Quality management and quality assurance , proposed by the General Department of Standards, Metrology and Quality, and published by the Ministry of Science and Technology.


This standard is built on two standards TCVN ISO/IEC 17025 and TCVN ISO 9001. This standard specifies competence and quality requirements specific to medical laboratories. Each country may have its own regulations or requirements that apply to some or all of the professional personnel and their activities and responsibilities in this area.
The services of a medical laboratory are essential to patient care and therefore should be available to meet the needs of all patients and medical professionals alike . responsible for patient care. These services include placement of test orders, patient preparation, patient identification, sampling, transportation, storage, handling, and testing of patient samples, along with interpretations, reports and follow-up advice, in addition to safety and regulatory considerations in medical laboratory work.
Where permitted by national , regional or local regulations or requirements, medical laboratory services should include testing of patients during consultations and these services should be subject to consultation. Actively involved in disease prevention in addition to patient diagnosis and management. Each laboratory should also provide appropriate educational and technical opportunities for specialized personnel working for it .
Although this International Standard is intended for use across all currently recognized areas of medical laboratory services, it may also be useful and relevant to organizations engaged in the services and fields of medicine. other areas such as clinical physiology, imaging, and medical physics. In addition, organizations involved in the accreditation of medical laboratory competence can also use this International Standard as a basis for their operations . If the laboratory wishes to be accredited, an accreditation body operating in accordance with TCVN ISO/IEC 17011 should be selected taking into account the specific requirements for the medical laboratory.
This International Standard is not intended to be used for accreditation purposes, however meeting the requirements of this standard by a medical laboratory means that the laboratory meets both the energy requirements and the requirements . technical and management system requirements necessary to provide technically valid results . The management system requirements in clause 4 are written in a language appropriate to the operation of the medical laboratory, in accordance with the principles of TCVN ISO 9001:2008 , Quality management systems - Requirements , and be happy a with appropriate laboratory requirements (IAF-ILAC-ISO Joint Communiqué issued in 2009).
The correlation between the clauses of this standard and the clauses of TCVN ISO 9001:2008 and TCVN ISO/IEC 17025:2007 is given in Annex A of the standard.
Environmental issues related to the operation of medical laboratories are covered in general throughout the standard, specific requirements are mentioned in 5.2.2, 5.2.6, 5.3, 5.4, 5.5 .1.4 and 5.7.
Medical laboratories - Requirements for quality and competence

1. Scope of application

This standard specifies requirements for the quality and competence of medical laboratories.
