Understanding how to interpret diagnostic test accuracy studies is a key skill that health practitioners need to develop in order to undertake evidence‐based practice.1 In this article we guide the reader through how to interpret a diagnostic test accuracy study, including the potential for bias. In subsequent articles we will discuss how diagnostic tests may be applied in clinical practice and consider key concepts in population screening and overdiagnosis.
