Abstract

In this article, we have discussed the basic knowledge to calculate sensitivity, specificity, positive predictive value and negative predictive value. We have discussed the advantage and limitations of these measures and have provided how we should use these measures in our day-to-day clinical practice. We also have illustrated how to calculate sensitivity and specificity while combining two tests and how to use these results for our patients in day-to-day practice.

摘要

在本文中，我们讨论了计算敏感性、特异性、阳性预测值和阴性预测值的基础知识。我们讨论了这些指标的优势和局限性，并说明了在日常临床实践中应如何使用这些指标。我们还举例说明了在结合两项检查时如何计算敏感性和特异性，以及在日常实践中如何将这些结果应用于我们的患者。
