Trial Outcomes & Findings for The Role of Chlorhexidine in Minimizing the Viral Load Among COVID-19 Patients (NCT NCT04941131)

NCT ID: NCT04941131

Last Updated: 2025-06-12

Results Overview

Gene viral load serves as a proxy measure for the presence and quantity of SARS-CoV-2 virus in patient samples. Since the E gene is expressed early and reliably during viral replication, changes in its detected levels reflect the dynamics of viral presence. Quantified using RT-qPCR, with results expressed as cycle threshold (Ct) values-the number of amplification cycles required to detect the gene above background levels. Lower Ct values indicate higher viral loads.
