Epstein‑Barr Virus Early Antigen D Antibody (IgG)
Also known as: EBV Early Antigen Diffuse Antibody, EBV EA-D Antibody
Use
IgG antibodies recognizing the Epstein‑Barr Virus Early Antigen D (EA‑D) typically emerge during acute infection—usually within a month of clinical presentation—and are transient, lasting approximately 3–4 months. Persistently elevated EA‑D IgG levels may suggest EBV reactivation or ongoing infection, including possible lymphoproliferative disorders.
Special Instructions
Not provided.
Limitations
This immunoassay detects diffuse (D) EA‑D IgG and does not differentiate between restricted (R) and diffuse (D) forms. IgG EA‑D levels may remain elevated for years in a minority of individuals. False‑negative results may occur in immunosuppressed patients. It should not be used as a standalone diagnostic; interpret results together with clinical evaluation and other EBV serologic markers (e.g., VCA, EBNA).
