Advances in Molecular Diagnostics in Clinical Microbiology: Transforming Detection, Surveillance, and Management of Infectious Diseases

Molecular diagnostics has transformed clinical microbiology by enabling rapid, sensitive, and specific detection of infectious pathogens. Traditional culture-based techniques require extended processing times and may fail to detect certain pathogens. Molecular diagnostic technologies including PCR, nucleic acid amplification tests, genomic sequencing, and nanodiagnostic platforms have significantly improved pathogen identification and infectious disease outbreak monitoring. This cross-sectional analytical study examines the role of molecular diagnostic technologies in clinical microbiology and their effectiveness in improving infectious disease detection and management across 232 diagnostic laboratory records and molecular testing reports. The molecular method type had the strongest association with diagnostic accuracy and treatment initiation time (F=8.12, p=0.001). AI-assisted interpretation and digital integration further enhance molecular diagnostic utility for precision medicine and public health surveillance. Molecular diagnostics are now essential components of modern clinical microbiology practice.
