What is the clinical significance of a 'One-step' RT-PCR assay in the detection of RNA viruses like SARS-CoV-2?
Show answer and explanation
Correct answer: It limits cross-contamination and speeds up sample processing
By performing the entire reaction in a closed-tube system, one-step RT-PCR reduces the number of pipetting steps. This is critical in clinical diagnostics to prevent 'carry-over' contamination and to streamline laboratory workflows.
