The measurement of viral load in the peripheral blood of patients with HDV infections isimportant for diagnosis, treatment monitoring, and support for follow-up studies of viral replication dur-ing the course of the disease. This study reports the development of an assay capable of detecting andquantifying the abundance of HDV particles in serum samples, based on reverse-transcription quantita-tive PCR (RT-qPCR). Two standards for calibration were produced for determining the viral load of HDV:a cDNA cloned into a linear plasmid and a transcribed RNA. For validating this assay, 140 clinical samplesof sera were used, comprising 100 samples from patients who tested positive for anti-HDV and hepatitisB virus surface antigen (HBsAg) by ELISA; 30 samples from blood donors; 5 samples monoinfected withhepatitis B virus (HBV); and 5 samples monoinfected with hepatitis C virus (HCV). The HDV RT-qPCR assayperformed better when calibrated using the standard based on HDV cDNA cloned into a linear plasmid,yielding an efficiency of 99.8% and a specificity of 100% in the in vitro assays. This study represents thefirst HDV RT-qPCR assay developed with clinical samples from Brazil and offers great potential for newclinical efficacy studies of antiviral therapeutics for use in patients with hepatitis delta in the western Amazon region.Hepatitis delta vírusHDV RNAQuantitative real-time PCRHydrolysis probeViral loadinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da
