Accreditation system

In addition, the bodies assessing the laboratories should comply with the general criteria for laboratory accreditation, such as those laid down in the ISO/IEC Guide 58 1993 Calibration and testing laboratory accreditation systems -General requirements for operation and recognition .13...

The two columns of laboratory results should be separated from the three columns of fertilizer values, either side-by-side or one over the other. To keep the report simple, laboratories may prefer not to present the laboratory results since the farmer is normally only interested in the fertilizer values. Some quality management or accreditation systems may require reporting of the laboratory results. These could be reported as the element, as shown here, or as the oxide for P, K, S and Mg.

Peer assessment is the cornerstone of many accreditation systems. The accreditation body maintains a staff of administrators and experts, but the majority of the work of assessments, including visits to the laboratories seeking accreditation, is performed by laboratory scientists, often volunteers, who... 

Another aspect of organizational management is the need for proper business procedures. The laboratory should not undertake work that results in a conflict of interest, and generally should not bring the accreditation system into disrepute by engaging in activities that would diminish confidence in the laboratory. 

While the specialist physician may develop an in-depth knowledge of the strengths and limitations of the laboratory that they use regularly, the occasional user and the patient require the reassurance offered by accreditation systems. In general, accreditation systems follow the principles of healthcare assessment described by Donabe-dian [5] ... 

When laboratories participate in an interlaboratory study, different sample pretreatment methods and techniques of separation and final determination are compared and discussed, as well as the performance of these laboratories. If the results of such an intercomparison are in good and statistical agreement, the col-laboratively obtained value is likely to be the best approximation to the true value. These collaborative trials can be held to evaluate the performance of a commonly applied method or the quality of a laboratory (e.g. in the context of accreditation systems), to improve the quality of a laboratory in a stepwise learning programme, and to certify the contents of a RM.

Improvement targets should be set in line with quality-control manuals used in other accreditation systems. It is always a good point to review internally and on a regular basis 1) problems that have been encountered in experimentation 2) audit findings 3) ways to improve work by looking at new systems and reviewing SOPs to ensure that these are current and 4) and areas where improvements can be made. 

An example can be taken from the accreditation systems, in which, in addition to QA audits, departments become involved in self-inspection. Each department can identify a QA representative whose daily responsibility is to review compliance issues, to look at the overall quality policy of the company, and to ensure that between QA audits, self-inspection is performed and that a departmental review is made of these findings with action points and a time plan identified. 

We decided to try DCM after several attempts at elaborate but spectacularly unsuccessful models of assessment that we d hoped would provide a common language and methodology for the entire college. Part of our motivation was to find a way to talk about assessment that matched a continuous Academic Quality Improvement Program (AQIP) that the college had moved to for its own accreditation. As part of the North Central Accreditation system, MMCC had adopted a model of quality improvement that put process ahead of results, so the assessment question became what...

The regulatory system needs further development. Specifically the system of import authorisations to the EU should be further developed and all countries should aim to establish systems that are fully compatible, transparent and easy to administer. Accreditation systems could play a key role in achieving this oljective, with the potential for fruitful involvement by non government actors like IFOAM. 

The main similarities of GLP and other laboratory quality systems may be seen in their focus on apparatus and instrument suitability, maintenance and calibration, where the requirements of accreditation systems go beyond what GLP is regulating, since these issues are of the utmost importance for generating accurate, precise and reproducible results. Thus, it has to be possible in every case to trace back the calibrations to the respective national standards of measurement, and the quality control of the measurements has to ensure that trends to deviations form the precision required are detected already early on. 

Matrix-matched CRMs are increasingly needed for a range of environmental matrices, elements or compounds, including materials certified for of>erationally-defined parameters (e.g. extractable trace element contents). Finally, training on the preparation of LRMs and use of CRMs should be systematised in the framework of accreditation systems. Such courses already exist [46] but are not fitted for purpose with respect to accreditation they should involve advice on how to develop LRMs versus CRMs, use RMs in sectorial proficiency testing (e.g. environmental monitoring) etc.

An analytical laboratory proves its effective quality assurance system by accreditation. Accreditation attests to the competence of a laboratory for performing given analytical methods versus an independent customer. In different countries, different accreditation systems have emerged. For example, in Germany, there is no central accreditation system, but a system that is decentralized to different sectors. 

The Commission of the European Union has harmonized the national accreditation systems. Unique criteria were developed for the operation of the test laboratories and for their accreditation and certification. The result of those harmonization policies is the series of directives Euronorm EN 45000 (Table 9.3). At present, all accreditations are performed on the basis of EN 45000.
