What is Norovirus PCR?
Norovirus PCR refers to the polymerase chain reaction method used to detect the RNA of norovirus, a leading cause of acute gastroenteritis outbreaks globally [CDC]. RT-PCR (reverse transcription PCR) is recognized as the "gold standard" due to its exceptional sensitivity and specificity for norovirus detection from human specimens such as stool and vomitus.
The molecular detection of norovirus has transformed outbreak response, hospital infection control, and food safety monitoring by enabling rapid identification even at low viral loads, with real-time results to support timely decision-making.

Industry Trends in Norovirus PCR
- Rising Global Demand: Since the COVID-19 pandemic, hospital and public health labs have rapidly expanded their molecular testing infrastructure, encouraging greater adoption of reliable norovirus PCR solutions.
- Multiplexing Capability: Many new assays now simultaneously detect norovirus GI and GII genogroups, reducing procedural time and maximizing laboratory throughput [NCBI].
- Automation and Workflow Efficiency: Automated PCR platforms minimize handling error while increasing accuracy, supporting widespread screening during outbreaks, in food production, and cruise ship health management.
- Quality Control & Regulatory Compliance: Validation against international standards (e.g., ISO 15216) is essential, ensuring results are robust and comparable across industries [ISO 15216].
