Abstract: Infectious diseases cause high morbidity and mortality, and early, effective antimicrobial therapy improves outcomes. However, conventional microbiology methods like culture are slow and insensitive. Emerging molecular diagnostics-such as multiplex PCR (mPCR), droplet digital PCR (ddPCR), and metagenomic next-generation sequencing (mNGS)-offer rapid, accurate pathogen identification. Challenges persist in result interpretation (e.g., setting positivity thresholds, low positive predictive value) and clinician trust. While molecular diagnostics excel in sensitivity, their real-world impact on specificity and patient prognosis - clinical accuracy -remains limited. Key hurdles include patient selection, timing, result interpretation, and pathogen relevance. Addressing these gaps is critical for standardizing these technologies and maximizing their clinical benefit.
