NASBA is an isothermal nucleic acid amplification reaction that amplifies mRNA in a dsDNA background. Although similar to the sensitive reverse transcription/ polymerase chain reaction (RT-PCR) in mRNA detection, NASBA is not prone to give false positive results caused by genomic dsDNA. Therefore, NASBA is unique for sensitive detection of transcription of intronless genes, which preclude strategies such as intron spanning primer pairs to control false positive results in RT-PCR.
