Rapid Diagnostic Techniques in Infectious Diseases: Technological Advances and Clinical Implications for Early Detection and Precision Treatment

Rapid diagnostic technologies have transformed the clinical management of infectious diseases by enabling early pathogen detection, improving treatment decision-making, and supporting effective infection control strategies. Traditional culture-based diagnostics often require 24–72 hours for results, delaying clinical decisions and increasing the risk of inappropriate empirical therapy. Modern rapid diagnostic techniques including molecular assays, biosensor technologies, nucleic acid amplification tests (NAAT), and point-of-care (POC) testing provide faster, more accurate pathogen identification. This cross-sectional analytical study examines the effectiveness and clinical utility of rapid diagnostic techniques across 226 diagnostic cases from hospital laboratories and infectious disease surveillance programmes. Rapid diagnostic technologies significantly reduce detection time and improve diagnostic accuracy compared with conventional methods. The diagnostic method had the strongest association with treatment initiation time (F=7.41, p=0.001). AI and digital health system integration further enhances disease surveillance and precision medicine in infectious disease management.
