Traditionally, microbiological approaches to diagnose infectious diseases have been labor-intensive and time-consuming; molecular methods significantly improve on these constraints. DNA microarray is a novel and advanced diagnostic test for infectious disease that is designed for specific identification of a wide variety of organisms simultaneously. Microarray has various advanced applications in infectious disease diagnostics, including the 2019 pandemic COVID 19, detection of food-borne infectious agents, and detection of Neisseria meningitidis. The aim of this review is to provide updated application of DNA microarray techniques for the diagnosis of infectious diseases and to explore the development of new DNA microarray methods. In conclusion, DNA microarray techniques are the future rapid and accurate diagnostic tool for infectious disease diagnosis and detection of antimicrobial resistance.Keywords: DNA microarray, infectious disease diagnostics, molecular techniques
