Abstract

LEGUIZAMON, John E; GONZALEZ, Ivonne A  and  BERNAL, Luisa J. Metrological needs in clinical laboratories. Rev.Colomb.Quim. [online]. 2014, vol.43, n.1, pp.30-35. ISSN 0120-2804.  https://doi.org/10.15446/rev.colomb.quim.v43n1.50539.

The results produced by clinical laboratories are key elements in the diagnosis and treatment of diseases and to monitor patients, so, it requires a metrological control over the measurement process, which will determine the degree of comparability and trust required on the obtained measurement results. Therefore, in this paper we discuss about the comparability of measurements and how it is influenced by factors such as commutability of reference materials, measurement methods, availability of materials and reference procedures, in addition to reference intervals and decision limits for a particular measurand. Finally it is exposed what are the mechanisms that allow ensure measurements comparability on this area.
