Emerging Trends
- Rapid growth of multiplex molecular testing: Healthcare providers are increasingly using multiplex PCR panels that detect multiple pathogens from a single sample. This reduces repeat testing and speeds treatment decisions. FDA-authorized multiplex assays can simultaneously identify viruses such as influenza A, influenza B, and SARS-CoV-2, improving laboratory efficiency and patient management.
- Expansion of genomic surveillance programs: Public health agencies are expanding next-generation sequencing (NGS) to monitor infectious diseases. Since 2014, the CDC’s Advanced Molecular Detection (AMD) program has strengthened pathogen surveillance by combining sequencing, bioinformatics, and epidemiology. The approach supports faster outbreak detection and tracks antimicrobial resistance and emerging variants.
- Greater adoption of bioinformatics and AI-supported analysis: Modern molecular diagnostics increasingly combine sequencing with advanced computational tools to interpret large genomic datasets. CDC’s AMD initiative integrates laboratory science, epidemiology, and bioinformatics, allowing faster identification of transmission patterns and supporting more accurate public health decisions during infectious disease outbreaks.
- Growing use of decentralized and near-patient molecular testing: Healthcare systems are adopting portable molecular diagnostic platforms that deliver highly accurate results closer to patients. Recent FDA-authorized molecular assays provide results in approximately 20–30 minutes, enabling earlier clinical decisions while reducing dependence on centralized laboratory infrastructure.
- Increasing focus on antimicrobial resistance surveillance: Molecular diagnostics are being integrated into surveillance systems to rapidly identify resistant pathogens. Genomic epidemiology enables laboratories to detect antimicrobial resistance markers while monitoring pathogen evolution, supporting infection control programs and guiding more targeted antimicrobial treatment across healthcare facilities.
Use Cases
