Mini review: Recent progress in RT-LAMP enabled COVID-19 detection.

Area of Science:

• Biotechnology and Biosensing
• Molecular Diagnostics
• Virology

Background:

• The COVID-19 pandemic, caused by SARS-CoV-2, necessitates rapid and accurate diagnostic tools.
• Current standard SARS-CoV-2 detection relies on reverse transcription polymerase chain reaction (RT-PCR), which has limitations in capacity and speed.
• RT-PCR requires specialized laboratory infrastructure and trained personnel, hindering widespread and timely testing.

Purpose of the Study:

• To review recent advancements in loop-mediated isothermal amplification (LAMP) for SARS-CoV-2 viral RNA detection.
• To highlight LAMP as a promising alternative to RT-PCR for pandemic surveillance.
• To discuss future research directions in LAMP-based biosensors for large-scale SARS-CoV-2 screening.

Main Methods:

• Review of current literature on LAMP methodology for SARS-CoV-2 detection.
• Analysis of LAMP's advantages over RT-PCR, including isothermal amplification and exclusion of thermal cyclers.
• Evaluation of LAMP's sensitivity, specificity, speed, and diagnostic capacity.

Main Results:

• LAMP enables rapid amplification of SARS-CoV-2 RNA at a constant temperature, eliminating the need for a thermal cycler.
• LAMP demonstrates comparable sensitivity and specificity to RT-PCR, with significantly faster turnaround times.
• The method offers potential for increased diagnostic capacity, crucial for effective pandemic monitoring.

Conclusions:

• Loop-mediated isothermal amplification (LAMP) is a highly suitable alternative to RT-PCR for SARS-CoV-2 detection.
• LAMP's advantages make it ideal for rapid, large-scale screening and effective pandemic management.
• Further research in LAMP-based biosensors can significantly advance global SARS-CoV-2 surveillance capabilities.
