Summary
The M10 (30-minute) and Flash10 PCR platforms showed high agreement with GeneXpert for detecting respiratory viruses. Comparative data is crucial due to performance variability among rapid diagnostic systems.
Area of Science:
- Molecular Diagnostics
- Infectious Disease Research
- Point-of-Care Testing
Background:
- Growing demand for rapid molecular diagnostics for respiratory viruses.
- Limited comparative performance data for available point-of-care PCR platforms.
Purpose of the Study:
- Evaluate diagnostic accuracy and operational reliability of four rapid PCR platforms.
- Compare performance against the GeneXpert platform for SARS-CoV-2, IAV, IBV, and RSV detection.
Main Methods:
- Nasopharyngeal swabs from symptomatic patients tested on GeneXpert.
- Positive samples analyzed on M10 (30-min and 1-hr), FlashDetect™ Flash10, Vivalytic, and Galaxy Lite systems.
- Inclusion of lower viral load samples and cultured influenza strains.
Main Results:
- M10 (30-min) showed 98.6% agreement; Flash10 showed 94.6% agreement with GeneXpert.
- Vivalytic achieved 83.0% agreement, Galaxy Lite 88.2% but with high failure rate.
- Performance varied, with some platforms missing low viral load samples and specific viruses.
Conclusions:
- M10 (30-min) and Flash10 platforms exhibited the highest agreement rates with GeneXpert.
- Significant performance variability necessitates independent evaluation of rapid PCR platforms.
- Data underscores the importance of platform selection for accurate respiratory virus diagnostics.
