Definition

[...] reverse transcription polymerase chain reaction (RT-PCR), which is a nucleic acid amplification (NAAT) test for COVID-19 diagnostics considered by the WHO and the ECDC to be the most reliable methodology for the testing of cases and contacts.

Encyclopaedic information

Many commercial NAATs that use RT-PCR rely on multiple targets to detect the virus, such that even if a mutation impacts one of the targets, the other RT-PCR targets will still work.
