Laboratory evaluation demonstrates that denaturing reagents and adjusted dNTP formulations alter RT-qPCR performance in clinical samples, indicating RNA structure impacts viral detection.

Key Points

To evaluate whether denaturing solutions (TEA and DMSO) and virus-adjusted dNTP proportions improve SARS-CoV-2 detection by mitigating RNA secondary structures in single and multiplex RT-qPCR assays.
Generated consensus sequences from 126,576 SARS-CoV-2 genomes using high-performance computing to design primers and probes targeting ORF8, E, N, and RNase P genes.
Tested single and multiplex RT-qPCR assays with denaturing additives (tetraethylammonium chloride and dimethyl sulfoxide) and viral-adjusted dNTP ratios on 49 clinical nasopharyngeal swab samples.
Identified positive SARS-CoV-2 detection in 22 of 49 clinical samples across the evaluated gene targets.
Observed variations in cycle threshold (Ct) values across single and multiplex RT-qPCR assays when incorporating denaturing solutions and tailored dNTP ratios.
