Applications of competitor RNA in diagnostic reverse transcription-PCR.

ABSTRACT: Detection of RNA viruses by reverse transcription (RT)-PCR has proven to be a useful approach for the diagnosis of infections caused by many viral pathogens. However, adequate controls are required for each step of the RT-PCR protocol to ensure the accuracies of diagnostic test results. Heterologous competitor RNA can be used as a control for a number of different aspects of diagnostic RT-PCR. Competitor RNA can be applied to assessments of the efficiency of RNA recovery during extraction procedures, detection of endogenous RT-PCR inhibitors that could lead to false-negative results, and quantification of viral template in samples used for diagnosis; competitor RNA can also be used as a positive control for the RT-PCR. In the present study, heterologous competitor RNA was synthesized by a
