摘要

选择对患者的测试及其解释是专家每天都要面对的事情,内镜医生对此并不陌生。在谈到诊断测试(实验室或成像)时,通常会听到灵敏度、特异性和预测值等参数的提及。所提到的参数(敏感性、特异性)确定了诊断测试的特征,有助于决定我们何时应该使用这些参数或测试结果对特定患者的意义。本研究的目的是为理解和应用诊断测试提供基本的统计概念。

Pruebas diagnósticas: aspectos básicos de lo que el endoscopista debe saber

Choosing a test on a patient and its interpretation is a daily occurrence that the specialist is faced with, and the endoscopist is no stranger to this. It is common when talking of a diagnostic test (laboratory or imaging) to hear the mention of parameters such as sensitivity, specificity and predictive values. The parameters mentioned (sensitivity, specificity) establish the characteristics of a diagnostic test and are useful to decide when we should use them or the meaning that a test result has in a particular patient.

The aim of the study is to present the basic statistical concepts for the understanding and application of diagnostic tests.
