Qualification Testing

This article provides insights into qualification testing, interlaboratory comparative testing, and qualification testing programs in testing laboratories that analyze the safety of meat and meat products. Samples with codes OK-MB- 21 were used as a model for interlaboratory comparisons. The uniformity and stability of the CC code was assessed in accordance with GOST R 50779.60-2017 “Statistical methods. Application in proficiency testing through interlaboratory testing ”. Seven laboratories participated in the proficiency testing program. The test preparation procedure was described and the test results determined whether each sample tested was satisfactory or questionable. Participants with unsatisfactory results are encouraged to identify the causes of the alarms, take corrective actions and document them, and identify and eliminate the causes of the unsatisfactory results.

Ethical dilemmas are commonly encountered by genetic counselors, whether in the clinical or laboratory setting. This chapter describes common ethical dilemmas, conflicts, and challenges encountered in genetic testing laboratories. These situations include genetic testing of minors for adult-onset conditions, prenatal testing, the ethical impacts of incidental findings and unexpected test results, and conflicts of interest. This chapter also explores the genetic counselor’s role in addressing ethical issues. Resources are provided for managing these ethical dilemmas within the laboratory.

National Institute for Food Control Proficiency testing plays a very important role in ensuring the quality of testing. Based on the results of the proficiency testing, the managers as well as the relevant members could assess the technical competence of the laboratory. Participating in proficiency testing is an evidence that a laboratory is implementing a quality management program in accordance with ISO/IEC 17025. Through the proficiency testing program, the participating laboratories themselves could evaluate their capabilities and address the causes affecting the quality of tests so as to take measures to ensure better quality assurance. This study provides a snapshot of the testing capacity of food testing laboratories within and outside the health sector based on chemistry proficiency testing conducted by the National Institute for Food Control (NIFC) in 2017.

KAN proficiency testing program on the bottled drinking water conducted on 2004 was participated by 46 testing laboratories. Participant laboratories were asked to test the sample for nitrat, nitrit, ammonium, sulphate Cl, Cn, F, F, Fe, Mn, Pb, Cu, Cd, As and Hg contents. Proficiency testing sample were prepared by provider, which also conduct homogeinity test for the Hg and Cu contents of the sample. As the sample was judged to be homogen, they sent to participant laboratory in 2 packs identified as sample KAN A and KAN B. Laboratory testing results were analyzed by statistical method, started on homogeinity of data, Dixon test and Z-score. The evaluation results shows that only sulphate, Cl, F, Fe and Cu contents could be analyzed among the other 14 parameters, which is could not be evaluated because of the in homogeinity of data provided by the laboratories. The inhomogeinity of data was caused by insufficiency of laboratory’s personnel and equipments. The evaluation of proficiency testing results for sulphate, Cl, F, Fe and Cu contents show only 1 satisfactory result among 5 accredited participants, and 9 satisfactory results among 39 non-accredited participants. The conclusion is based on the Z-score analysis of the evaluated parameters.

Conformity Assessment Body

INSEMEX-OEC is a Conformity Assessment Body for certification activities in accordance with ATEX Directive 2014/34/EU, being accredited by RENAR and notified to Brussels (NB1809). INSEMEXGLI (Group of Testing Laboratories) is the main provider of laboratory testing services for the product certification body INSEMEX-OEC. The test laboratories meet the requirements of the standard SR EN ISO / IEC 17025. This standard requires laboratories to have a procedure in place to monitor the validity of the test results. This monitoring must be planned and, if possible, should include participation in inter-laboratory comparisons or proficiency testing programs. This paper presents some specific issues highlighted during the successful participation of INSEMEX-GLI in a round of inter-laboratory comparisons organized by the Physikalisch-Technische Bundesanstalt from Germany to determine International Protection Code (IP Code) for equipment enclosures.

Standaridizing test results for rheumatoid factor by comparing results obtained for an unknown with results obtained for a serum reference preparation decreased variance between laboratories, as measured in the Center for Disease Control proficiency testing program, by 77%. The amount of improvement was also estimated by the type of test and by the manufacturer's product. Standardization resulted in an increase in the number of reported results that were within a twofold dilution of the median value. The percentage increased from 50.3 to 93.7% for the slide tests and from 78.1 to 91.2% fro the tube tests. Decrease in variance by manufacturer's product ranged from 94 to 27%. The study demonstrated that adopting a reference serum standard could substantially improve the comparability of rheumatoid factor test results and that proficiency testing programs can be used to estimate improvement which could be expected as a result of standardization.
