The Epstein-Barr Virus (EBV) Comprehensive Panel measures VCA IgM, VCA IgG, EBNA IgG, and Early Antigen D IgG antibodies to evaluate stage of EBV infection. This virus causes mononucleosis and has links to chronic fatigue, autoimmune conditions, and certain cancers. Doctors order this test for patients with fever, sore throat, lymph node swelling, or prolonged fatigue. Results help distinguish acute, past, or reactivated EBV infection and guide clinical care.

The Epstein-Barr Virus Antibody (EBV) Panel detects antibodies to EBV, including VCA IgM, VCA IgG, and EBNA IgG, to determine current, recent, or past infection. EBV causes infectious mononucleosis and has links to chronic fatigue and certain cancers. Doctors order this test for patients with fever, sore throat, swollen lymph nodes, or fatigue. Results help identify stage of infection, confirm diagnosis, and guide clinical management of EBV-related illness.

The Quantitative Epstein-Barr Virus (EBV) DNA Real-Time PCR Test measures the amount of EBV genetic material in blood to monitor viral load. Unlike antibody tests, it directly tracks EBV activity, making it vital for transplant patients, immunocompromised individuals, or those with chronic EBV. Doctors order this test to evaluate risk of complications, guide treatment, and monitor response to therapy by quantifying EBV levels over time.

The Epstein-Barr Virus (EBV) Viral Capsid Antigen (VCA) IgA Antibody Test detects IgA antibodies that may indicate recent or reactivated EBV infection. Elevated IgA levels are often associated with nasopharyngeal carcinoma and other EBV-related conditions. Doctors order this test for patients with persistent sore throat, swollen lymph nodes, or suspected EBV reactivation. Results provide valuable insight for diagnosis, cancer risk assessment, and ongoing monitoring.

The Epstein-Barr Virus (EBV) Early Antigen D IgG Antibody Test detects IgG antibodies to EBV’s early antigen, helping identify recent or reactivated infection. Elevated levels may indicate acute mononucleosis, viral reactivation, or chronic EBV. Doctors order this test when patients present with fatigue, fever, sore throat, or swollen lymph nodes. Results provide key insight into EBV activity, supporting diagnosis, monitoring, and treatment decisions.

The Epstein-Barr Virus (EBV) Nuclear Antigen (EBNA) IgG Antibody Test detects IgG antibodies that usually appear after acute infection, confirming past exposure or infection recovery. Doctors order this test alongside VCA and EA antibodies to determine the stage of EBV infection. Results help distinguish recent versus past EBV, guide diagnosis of mononucleosis, and support evaluation of chronic fatigue or EBV-related health conditions.

The Epstein-Barr Virus (EBV) Viral Capsid Antigen (VCA) IgG Antibody Test detects IgG antibodies that appear after EBV infection and usually persist for life. Positive results indicate past exposure or infection with EBV, the virus that causes mononucleosis. Doctors order this test with VCA IgM and EBNA IgG to determine infection stage. Results help confirm prior EBV exposure, support diagnosis, and guide evaluation of EBV-related conditions.
