Application and Modification of RT-LAMP for Rapid Detection of SARS-CoV-2 Viral Genome

COVID-19 outbreak caused by the newly discovered SARS-CoV-2 has become a major public health threat around the world and has create a tremendous effect on the global economy. Hence, there is a high demand for rapid and accurate diagnosis to contain the spread of the disease. The Reverse-Transcription Polymerase Chain Reaction (RT-PCR), the current standard for diagnosis of COVID-19 however possesses certain drawbacks that limits its application to meet the high demand of the continually increasing COVID-19 cases. Conversely, Loop-Mediated Isothermal Amplification (LAMP) is another nucleic acid amplification method that shows a great potential as an alternative tool in rapid diagnosis of COVID-19 due to its simplicity and rapidity. This review summarized the recent published research articles related to the application and modification of RT-LAMP assay for the rapid detection of COVID-19 in comparison with other available diagnostic methods.
