Hepatitis D Virus (HDV) Antibody, IgG and IgM
Also known as: HBV, Hepatitis delta
Use
This assay is used for the qualitative detection of Hepatitis D virus (HDV) antibodies (IgG/IgM) and is intended to aid in the diagnosis of HDV infection in individuals with known HBV infection (HBsAg-positive). Testing for HDV RNA should be performed on HDV antibody-positive individuals to differentiate between active and resolved HDV infection.
Special Instructions
Not provided.
Limitations
A reactive specimen should be investigated further with sensitive, supplemental HDV-specific tests, such as identification of HDV RNA, to be matched with the clinical story of the subject and with markers of a previous HBV infection (HBsAg, anti-HB Core, HBV DNA, etc.). Like all immunoassays, this assay may occasionally yield nonspecific reactions due to other causes. A nonreactive test result for HDV antibodies does not exclude the possibility of exposure to or infection with HDV. Further investigations with alternative HDV-specific tests are suggested in case of suspected infection despite the negative finding.
