Resumen

El presente artículo es de divulgación de un importante capítulo de la epidemiología clínica que se refiere a la evaluación de las Pruebas Diagnósticas. Recurriendo lo mínimo posible a las fórmulas matemáticas, se explica el significado llano y la interpretación funcional de los índices diagnósticos más importantes que caracterizan a las mismas, para desde este punto describir su traslado a la práctica clínica diaria, especialmente en lo que afecta a la confección de un protocolo diagnóstico. No se analizan aspectos relacionados con la medicina basada en la evidencia, lo que constituiría el siguiente escalón una vez dominados estos conceptos.

The present article aims to disseminate knowledge of a topic that is important in clinical epidemiology: evaluation of diagnostic tests. Mathematical formulae are kept to a minimum. The significance and interpretation of the most important diagnostic indexes characterizing these tests are explained in order to describe their use in daily clinical practice, especially their role in the design of diagnostic protocols. Features related to evidence-based medicine, which represent the next step after mastery of these concepts, are not analyzed.
