Hepatitis B Viral DNA, Quantitative

Overview

  • EPIC Code:
  • LAB951
  • Soft Test Code:
  • HBVDN
  • Send Out Test Code:
  • 8369
Alternate Names
  • Hep B Viral DNA, Quant
  • Hepatitis B Virus DNA, Quantitative, Real-Time PCR
  • Hepatitis B Virus Quant DNA
Clinical Significance

Chronic carriers will persist in producing detectable HBV. Patients with chronic liver disease of unknown origin most commonly have HBV that is detected by viral DNA testing. Quantitative measurement of HBV viral DNA may be used to monitor progression of disease.
