Anti-HIV quality assurance programs in Australia and the southeast Asian and Western Pacific regionsSpringer Science and Business Media LLC - Tập 6 - Trang 168-172 - 2001
A. Gust, Sandy Walker, Roderick J. Chappel, Elizabeth M. Dax
Anti-HIV testing is the most regulated area of laboratory medicine in Australia. These regulations have placed the National Sero-logy Reference Laboratory, Australia (NRL) in a unique position to implement a comprehensive quality assurance (QA) program for HIV testing. The elements of our QA program include pre-market evaluation of assays, external quality assessment schemes (EQAS), quality contro...... hiện toàn bộ
Linearity of calibration curves: use and misuse of the correlation coefficientSpringer Science and Business Media LLC - Tập 7 - Trang 281-285 - 2002
Joris Van Loco, Marc Elskens, Christophe Croux, Hedwig Beernaert
The correlation coefficient is commonly used to evaluate the degree of linear association between two variables. However, it can be shown that a correlation coefficient very close to one might also be obtained for a clear curved relationship. Other statistical tests, like the Lack-of-fit and Mandel’s fitting test thus appear more suitable for the validation of the linear calibration model. A numbe...... hiện toàn bộ
Homogeneity testing of reference materialsSpringer Science and Business Media LLC - Tập 3 - Trang 51-55 - 1998
J. Pauwels, Andrée Lamberty, Heinz Schimmel
Homogeneity testing is of the highest importance for the certification of reference materials, as it should demonstrate the validity of the certified values and their uncertainties in the analysis of individual units or portions thereof. However, the conclusions drawn from the results of these studies may often be questioned. It is proposed to improve this situation by quantifying the effect of h...... hiện toàn bộ
