HEPATITIS D ANTIGEN

Hepatitis D antigen, or delta antigen (HDAg), is a protein associated with the Hepatitis D virus (HDV). HDV, a unique form of viral hepatitis, requires the presence of the Hepatitis B virus (HBV) for its replication. The delta antigen is crucial for HDV replication and is used as a marker to detect active Hepatitis D infections. Testing for Hepatitis D antigen involves blood tests, and a positive result indicates the presence of the virus. Co-infection with Hepatitis B and Hepatitis D can lead to more severe liver disease. If there are concerns about Hepatitis D, individuals should consult with a healthcare professional for appropriate testing and guidance.
