In West Germany the Giessen-test (G.T) is one widespread personality test, specially in the stress – related disorders. Giessen-test itself consists of 40 items which is grouped into 6 main scales. 183 healthy students are studied by this test. In comparison the result of G.T in medical students of Ha Noi and in Bulgarian young people, there are significant differences in 4 scales of this test (scale 2; 3; 5; 6). However, the difference in 2 scales (scale 1; scale 4) is uncertain. The difference between male and female students is found insignificantly in our research according to G.T scales. In order to have the result of exact standardization, we must research this test on the population larger with different ages and professions.

Grounding impedance measurement is a traditional proficiency testing programs, 2014 proficiency testing program on the basis of original ability to verify, combined with actual detection need, innovation introduced two verification point of the power input socket and metal plane testing. This paper analyzes and discusses the results of the ability verification in 2014, and puts forward the points of attention and the recommended method of metal plane test.

The safety and effectiveness of medical devices are directly related to human health. Therefore, how to improve the accreditation validity of medical devices testing laboratory has been the focus of attention from every corner of society. With respect to the characteristics of medical devices testing laboratory, this paper represented the existing issues during the accreditation and evaluation of testing laboratory, put forward some improvement suggestions on how to improve the validity of testing laboratory evaluation based on the practical experience.

Laboratories working towards accreditation by the International Standards Organization (ISO) 15189 standard are required to demonstrate the validity of their analytical methods. The different guidelines set by various accreditation organizations make it difficult to provide objective evidence that an in-house method is fit for the intended purpose. Besides, the required performance characteristics tests and acceptance criteria are not always detailed. The laboratory must choose the most suitable validation protocol and set the acceptance criteria. Therefore, we propose a validation protocol to evaluate the performance of an in-house method. As an example, we validated the process for the detection and quantification of lead in whole blood by electrothermal absorption spectrometry. The fundamental parameters tested were, selectivity, calibration model, precision, accuracy (and uncertainty of measurement), contamination, stability of the sample, reference interval, and analytical interference. We have developed a protocol that has been applied successfully to quantify lead in whole blood by electrothermal atomic absorption spectrometry (ETAAS). In particular, our method is selective, linear, accurate, and precise, making it suitable for use in routine diagnostics.
