Technical Parameters & Standardization

An advanced norovirus detection kit is designed to provide accurate, rapid, and robust detection across varied environmental and biological samples. Core parameters dictating performance include:

  • Sensitivity (LoD): Lowest quantity of viral RNA (copy/μl) reliably detected, crucial for early outbreak diagnosis.
  • Specificity: Ability to exclude cross-reactivity (norovirus GI vs. GII, false positives with enteric viruses).
  • Detection Time: Turnaround from sample prep to result (Trade-off: speed vs. accuracy).
  • Storage Condition: Lyophilized/nucleic acid stabilizer for ambient storage, critical in field deployment.
  • Certifications: Products adhering to ISO 13485 (Medical devices — Quality management), FDA EUA, CE-IVD.
