Reverse Transcription Loop-mediated Isothermal Amplification

Schematics of RT-LAMP amplification, exemplified for SARS-CoV-2detection.

Reverse transcription loop-mediated isothermal amplification (RT-LAMP) is a one step nucleic acid amplification method to multiply specific sequences of RNA. It is used to diagnose infectious disease caused by RNA viruses.[1]

It combines LAMP[2] DNA-detection with reverse transcription, making cDNA from RNA before running the reaction.[3] RT-LAMP does not require thermal cycles (unlike PCR) and is performed at a constant temperature between 60 and 65 °C.

RT-LAMP is used in the detection of RNA viruses (groups II, IV, and V on the Baltimore Virus Classification system), such as the SARS-CoV-2 virus[4] and the Ebola virus.[5]
