Also known as: EBV A
Use
The Epstein-Barr Virus (EBV) Antibody to Viral Capsid Antigen, IgA test is used to aid in the detection and prognosis of nasopharyngeal carcinoma. It is not suitable for diagnosing Epstein-Barr virus infectious mononucleosis. This test measures the IgA antibodies against the viral capsid antigen of EBV, which can play a role in diagnosing certain EBV-related conditions, particularly in the context of nasopharyngeal carcinoma, where EBV is often associated.
