Performance Evaluation of Nucleic Acid Detection Reagents and Verification of Various Factors Affecting the Efficiency of Nucleic.
Background: Since the COVID-19 outbreak in 2019, nucleic acid testing has been central to epidemic control and clinical decision-making. However, variability in assay kits and extraction steps can affect sensitivity, specificity, and reproducibility. Systematic evaluation of detection reagents and extraction efficiency is essential to ensure reliable clinical results. Objective: This study aimed to evaluate whether three domestic novel coronavirus nucleic acid detection kits based on fluoresc...
