Evaluación de tecnologías diagnósticas y tipos de muestreos

Abstract

For the researcher evaluating sampling diagnostic technology, the present revision and up-dating of diagnostic and sampling techniques has as its objective the demonstration of how they can be used to reduce costs and risks and how to carry out test characteristics' calculations, to establish sensitivity, specificity, positive predictive value and negative predictive value, in an unbiased way in a representative sample of the population in which the test will be used and to give recommendations to prevent errors which frequently occur in test evaluation, such as in pseudo-retrospective sampling.
