The Schemes of External Quality Control in Laboratory Medicine in the Balkans There are many differences between the national External Quality Control Schemes all around Europe, but the most important ones are certainly those between the countries of the Balkan region. These differences are due to these countries' different political and financial development, as well as to their tradition and the development of clinical chemistry science in each one. Therefore, there are Balkan countries with very developed EQAS and others where there is no such a scheme. Undoubtedly, the scientific community in these countries wants to develop EQAS despite of the financial and other difficulties.

Faecal Culture

In Finland, all laboratories carrying out diagnostics of infectious diseases in humans are approved by the Regional State Administrative Agencies and are obligated to participate in External Quality Assurance rounds. Performance in these rounds is thought to reflect the quality of laboratory work. In the 6-year study period, 17 Finnish laboratories received 48 simulated faecal specimens for the culturing of diarrhoeal pathogens, yielding altogether 586 faecal culture External Quality Control specimens and 581 reports. The results were correct in 92% of all reports and in 67% of all specimens. False-negative Salmonella results were given for 2 of the 18 specimens, one with biochemically atypical Salmonella strain and the other with a low count of Salmonella cells. False-negative Shigella report was given for 6 of the 7 specimens in some participating laboratory. Detection of all common faecal pathogens is especially relevant to patient safety, public health, and epidemiological surveillance.

External quality control of the chemical-analytical departments of the central factory laboratories was carried out: PJSC Krasnoarmeysky Dinas Factory, PJSC Chasovoyarsk Refractory Plant, PJSC Velikoanadol Refinery Plant. During the chemical analysis of samples of refractories of the listed enterprises, the analysis methods, equipment and materials described in DSTU 3305(3, 4, 5)—96 (GOST 2642.(3, 4, 5)—97) — gravimetric (SiO2), complexometric (Al2O3), photometric (Fe2O3). As a result of the work carried out, conclusions were drawn up in which the quality of the work of the chemical analytical units of the central factory laboratories of the PJSC “Krasnoarmeysky Dinas Factory”, PJSC “Chasovoyarsk Refractory Plant”, and PJSC “VELIKOANADOL REFRACTORY PLANT” was considered satisfactory.

21 Hydroxylase Deficiency

AbstractThe measurement of 17α-hydroxyprogesterone (17α-OHPR) is of value for the diagnosis and management of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. In the central laboratory from 2000 to 2002, we observed, using the assay from the manufacturer DSL, an elevation of the moving average of 17α-OHPR concentrations and a number of adrenocorticotropic hormone (ACTH) stimulation tests despite the lack of any changes to the internal and external quality control, of which the criteria were continuously fulfilled. We studied a population of n=49 patients for the measurement of 17α-OHPR, with and without extraction, to evaluate the quality of different commercially available radioimmunoassays. The internal and external quality controls were successful in determining 17α-OHPR. An excellent measurement and correlation of 17α-OHPR was expressed with the assay from the manufacturer IBL without extraction and from the manufacturer DSL with extraction. The quantitative determination of 17α-OHPR requires adequate specificity and accuracy of the 17α-OHPR radioimmunoassays. The results show that internal and external quality control systems are not sufficient to resolve analytical problems described in this study.
