StayinThailand2much Posted November 24, 2021 Share Posted November 24, 2021 What is a 'RT-PCR (NAAT) test', and is this the standard RT-PCR test you get in Bangkok, when you do the test at a hospital or clinic? Link to comment Share on other sites More sharing options...

Just want to make sure it's the same as the one with the 'NAAT'... Link to comment Share on other sites More sharing options...
partington Posted November 25, 2021 Share Posted November 25, 2021 (edited) In case you haven't got the 1 second it takes to Google this, NAAT stands for nucleic acid amplification test. An RT-PCR is one kind of NAAT, the most common kind for Covid -19 virus detection. It detects the nucleic acid of COVID-19- which is RNA- after conversion to the nucleic acid DNA, which is done by the RT (reverse transcriptase) step. It relies on usually 40 repeated thermal cycles -commonly 94°C for followed by 68°C. But new technology now means there are several other kinds of nucleic acid amplification tests to detect the nucleic acid of Covid-19. They are also NAATs, but they are not identical to RT-PCR, being based on different methods of amplifying the nucleic acid . For example there are amplifications that can be done at a single temperature (isothermal). However if it is called an RT-PCR (NAAT) it should be the same as a test called simply RT-PCR.

Thank you for the detailed post. All I wanted to know, was whether all the RT-PCR tests offered in Bangkok are the same, "RT-PCR (NAAT)" required by some countries to enter. Reading your explanation, it seems they are. Edited November 25, 2021 by StayinThailand2much Link to comment Share on other sites More sharing options...
