Diagnostic accuracy is a measure of how well a medical test identifies whether a particular disease or condition is present, expressed through metrics such as sensitivity, specificity, predictive values, and likelihood ratios. Sensitivity describes how often a test correctly identifies people who have the condition, while specificity describes how often it correctly identifies those who do not; together with predictive values they indicate how much a positive or negative result should change clinical judgment. Diagnostic accuracy is typically established by comparing a test against a reference or gold-standard method in a defined population, and it depends on factors such as the disease prevalence, the threshold chosen for a positive result, and the quality of the comparison standard. Reliable accuracy estimates are essential for deciding which tests to use, interpreting results, and avoiding the harms of false positives and false negatives. The concept applies across imaging, laboratory, microbiological, and emerging computational methods. Within the scope of Etiological Diagnosis, which addresses the identification of disease causes and the performance of diagnostic methods, this page gathers peer-reviewed, open-access research relevant to diagnostic test performance, including comparative studies of imaging modalities, microbiological assays, and other techniques against reference standards across a range of clinical conditions.
