Neutrophil extracellular traps (NETs) play a crucial role in the pathogenesis of autoimmune diseases, acting as both a defense mechanism and a potential source of autoantigens that exacerbate disease progression. The detection and quantification of NETs in autoimmune conditions have become pivotal for understanding disease mechanisms, developing diagnostic tools, and evaluating therapeutic strategies. This review aims to provide a comprehensive overview of the current methodologies used for detecting NETs in autoimmune diseases, including immunofluorescence microscopy, ELISA, flow cytometry, and advanced imaging techniques. We will discuss the challenges associated with NET detection, such as specificity, sensitivity, and the influence of disease state on NET formation. Furthermore, the review will explore the clinical implications of NET detection, highlighting its potential role in disease monitoring, prognostic assessment, and therapeutic targeting in autoimmune conditions.
