Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses a significant global health threat.
- Current diagnostic methods like RT-PCR have limitations, including high costs and infrastructure requirements.
Purpose of the Study:
- To present a protocol for detecting SARS-CoV-2 using reverse transcription-loop-mediated isothermal amplification (RT-LAMP).
- To offer a cost-effective and accessible alternative to existing diagnostic methods.
Main Methods:
- Development of a protocol for SARS-CoV-2 detection via RT-LAMP.
- Includes steps for in silico primer design, reagent preparation, amplification, and visualization.
- Focuses on adaptability for various laboratory and point-of-care settings.
Main Results:
- The RT-LAMP protocol allows for rapid detection of SARS-CoV-2 within 60 minutes.
- Requires inexpensive equipment and minimal specialized infrastructure.
- Demonstrates adaptability for detecting multiple pathogens.
Conclusions:
- RT-LAMP provides a viable, low-cost, and rapid method for SARS-CoV-2 detection.
- The protocol is easily implementable in diverse settings, including field and health centers.
