Alternative methods for internal quality control in research laboratories for environmental analysis: a programme for the performance evaluation of equipment, methods and staff

In analytical research laboratories, the problem of quality assurance is more difficult to solve than in laboratories devoted exclusively to routine analysis: the former usually have to deal with a much greater variety of samples and may have to develop entirely new methods of analysis. For research laboratories we have developed several alternative methods of quality assurance. These methods can be used to distinguish between different analytical methods, between different types of equipment, between different levels of skill among laboratory technicians, or even between the performance of technicians of the same level of skill.     

Quality assurance in the microbiology laboratory

 The pertinent issues necessary for the establishment of quality assurance in the microbiology laboratory are discussed. Quality assurance is a planned system of control measures that enables management to ensure that the analytical data produced in the laboratory are valid. To introduce quality assurance, all activities in the laboratory that affect the production of analytical data must be documented and controlled. These include sampling, method selection, laboratory environment, equipment, reagents and media, staff, reference materials and internal and external quality control. Laboratory accrediation in accordance with EN45001 and ISO Guide 25 enables laboratories demonstrate to an external agency their ability to perform analytical work and produce valid analytical data. This gives creditability to the laboratory and allows management to have confidence in the data produced. Received: 6 June 1995 Accepted: 3 July 1995     

Why do food analysts need quality assurance?

 Most sophisticated products require testing for compliance with specifications and safety regulations before release into many markets, and trade in many simpler commodities and products also requires supporting technical information. Test documentation has become an essential element in this trade. Food intended for human consumption certainly falls into the "sophisticated products" category. Lack of acceptance of laboratory test data across national borders may be a significant barrier to trade. In order to avoid such barriers and unnecessary duplication of laboratory tests, mutual recognition of laboratory results should be regarded as an important means of facilitating international trade in food products. It is difficult to envisage recognition of test data across borders without internationally agreed criteria for assessing the competence of testing. These criteria should, as a minimum, require that a laboratory involved in the analysis of foods operates a suitable quality system. The laboratory must create a quality system appropriate to the type, range and volume of work performed. It is necessary for the elements of this system to be documented in a quality manual which is available for use by the laboratory personnel. The quality manual must be kept up-to-date by a person or persons having responsibility for quality assurance within the laboratory. This paper describes and discusses the elements of a quality system in a food laboratory, including suitable quality assurance measures, the use of validated analytical methods and participation in proficiency testing schemes.

Establishing a quality assurance plan for nucleic acid-based diagnostic laboratories: from planning to implementation

Nucleic acid-based technologies have opened new perspectives in diagnosis, prognosis, and treatment in clinical medicine. To maintain patient confidence in this rapidly expanding field and to provide the highest standard of analysis, strict laboratory quality assurance procedures must be followed. While impressive break-through are taking place in this field, the need for an appropriate and suitable quality assurance (QA) plan for nucleic acid-based diagnostic laboratories must be a top priority. In this study, we developed a systematic QA plan for this kind of diagnostic laboratories that would enable us to assure the highest quality standards of their services. We focus on those labs that would like to start introducing a quality system for the first time and discuss the most appropriate ways to pave the way to implement a QA plan from the beginning. This QA plan is suitable for any nucleic acid-based techniques laboratory regardless of the field or services provided.

Quality assurance in analytical measurement

 The peculiarities of analytical measurement require to check characteristics of the error (its components) of the obtained analysis results to assure the quality of the measurements. This article deals with the various quality assurance procedures and algorithms which are used to check the quality indices, i.e. the accuracy, reproducibility, certainty and repeatability of analytical measurements: These procedures include: laboratory rapid control; Intra-laboratory statistical control (statistical selection control by alternative attribute, statistical selection control by quantity method of periodic check of the analysis procedure for conformity to the specified requirements) and external control (inter-laboratory control checks, inter-laboratory comparison tests, and intra-laboratory control algorithms carried out by the appropriate supervisory body.) in the separately taken laboratory. The respective algorithms, control plans and control requirements, specified according to the different control aims and assurance tasks, enable the quality and certianty of analytical information obtained in laboratories in Russia to be assured.

Metrology in laboratory medicine – A necessity

 In a recent Letter to the Editor, Dr. B. Neidhart questioned the need to make clinical chemical measurement results traceable to international standards and to incorporate the principles of analytical quality assurance into clinical chemistry. An analysis of the arguments presented shows that modern laboratory medicine has to deliver accurate results, which are comparable over space and time, in order to improve the accuracy of diagnostic tools and minimize cost. The means to achieve accuracy and comparability are metrological traceability and quality assurance as supported by many national and international initiatives.     

QASKI – the quality assurance system of the National Institute of Chemistry

 The quality assurance system (QASKI) developed and implemented in the National Institute of Chemistry is presented. It tries to eliminate the incompatibilies between the present methods of quality assurance used in research and development institutes such as good laboratory practice and accreditation. Since 1991, QASKI has been used for internal accreditation of laboratories located in the institute, regardless of the fact that some of them deal with routine analyses and others with research and development. Every laboratory that wishes to ensure the credibility of its research or routine work enters QASKI and at the same time chooses an external method of approval. All interested laboratories, study directors, principal investigators, internal auditing staff, heads of documentation, quality assurance unit staff, the Director of the institute and the Quality Management Board participate in the internal system.     

Quality assurance in the view of a commercial analytical laboratory

 The necessity for analytical quality assurance is primarily a feature of the analytical process itself. With the full establishment of the EU domestic market, it is also becoming a legal necessity for an increasing number of analytical laboratories. The requirements which laboratories will need to fulfil are stipulated in DIN EN 45 001. Accredited testing laboratories must in fact provide evidence that they work solely in accordance with this standard. National and EU commissions, which are legislative authorities, tend therefore to specify analytical methods, e.g. in the form of regulations or appendices thereto, intended to ensure that results from different laboratories will be comparable and hence will stand up in a court of law. The analytical quality assurance system (AQS), introduced by the Baden-Württemberg Ministry for the Environment in 1984, obliges laboratories to regularly participate in collaborative studies and thereby demonstrate their ability to provide suitably accurate analyses. This alone, however, does not sufficiently demonstrate the competence of a laboratory. Only personal appraisal of the laboratory by an auditor, together with the successful analysis of a sample provided by the same and performed under his observation, can provide proof of the competence of the laboratory. From an analytical point of view, the competence of a laboratory must be regarded as the decisive factor. Competence can only be attained through analytical quality assurance, which thus must be demanded of all laboratories. Received: 4 October 1996 Accepted: 15 January 1997
