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.

Examples
Diagnosis of COVID-19 was confirmed by PCR test in 90% of participants.
Source: https://files.covid19treatmentguidelines.nih.gov/guidelines/covid19treatmentguidelines.pdf
In a recent study, only 9 out of 19 (47%) oropharyngeal swabs from COVID-19 patients tested positive by RT-PCR.

The procedures involved in laboratory RT-PCR testing for SARS CoV-2 using a number of assays currently in use are well described.
