Hepatitis Delta Antigen by ELISA
Also known as: HEPD AG
Use
This test is used to detect the presence of Hepatitis Delta antigen in serum using a qualitative enzyme-linked immunosorbent assay (ELISA). The presence of antigens indicates an active Hepatitis Delta Virus (HDV) infection. However, this test is not recommended for HDV screening, diagnosis, or monitoring therapy. Preferred alternatives include Hepatitis Delta Virus Antibody tests or Hepatitis Delta Virus Antibody by ELISA with reflex to quantitative PCR.
Special Instructions
Test is not performed at ARUP Laboratories, and separate specimens must be submitted for multiple test orders. Ensure specimen storage and transport conditions are strictly followed. Critical frozen handling is necessary to ensure sample integrity.
Limitations
This test cannot be used for screening or diagnosing Hepatitis Delta Virus (HDV) or monitoring therapeutic responses. Negative results do not rule out HDV infection due to potential low viral loads or antigen levels below the assay's detection threshold. Positive results need to be interpreted with additional clinical and laboratory evidence. Equivocal results should be confirmed with a follow-up sample collected within 7-14 days.
