Diagnostic Markers Significance
Anti-HDV IgG antibody
  • Positive in persons exposed to HDV
  • Persists, even after viral clearance
Anti-HDV IgM antibody
  • Positive in acute infection
  • Negative in past infection
  • Persists in many patients with chronic infection
HDV RNA

Qualitative

  • Marker of HDV replication
  • Positive in chronic infection
  • Negative in spontaneous or treatment-induced viral clearance

Quantitative

  • Useful in monitoring or predicting treatment response
HBsAg

Qualitative

  • Must be positive for HDV infectivity

Quantitative
