A mobile, colorimetric reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay using saliva effectively identifies SARS-CoV-2, even in asymptomatic individuals, overcoming testing limitations.
Area of Science:
- Molecular Biology
- Virology
- Public Health
Background:
- Testing limitations hinder Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) control in the United States.
- Current testing modalities often fail to identify asymptomatic individuals, limiting effective disease containment.
Conclusions:
- The mobile RT-LAMP assay is a rapid and effective method for detecting SARS-CoV-2 RNA in saliva.
- This assay can be implemented outside traditional laboratory settings by individuals with basic molecular biology skills.
- The method successfully identifies asymptomatic individuals, thereby addressing a critical gap in current SARS-CoV-2 testing strategies.
