What is the normal range for EBV?
Optimal Result: 0 – 17.9 U/mL. EBV-VCA, IgG is an antibody (protein) that is produced by the body in an immune response to an Epstein-Barr virus antigen. EBV stands for Epstein-Barr virus. Epstein-Barr virus is a virus that typically causes a mild to moderate illness.
How do you read EBV labs?
If someone has positive VCA-IgG and EA-D IgG tests, then it is highly likely that the person has a current or recent EBV infection. If the VCA-IgM is negative but VCA-IgG and an EBNA antibody are positive, then it is likely that the person tested had a previous EBV infection.
What is a high viral load for Epstein-Barr?
Chronic high-load state was defined as the presence of >16,000 genome copies/mL whole blood on > or =50% of samples over at least 6 months.
When does EBV IgG become positive?
Although not always present, EA (D) IgG increases during the first 3-4 wk and is no longer detectable after 3-4 mo (approximately 85% of the patients with acute infection are positive for up to 3 mo after symptom onset)[23,24], even though in some cases they can still be detected years after a primary infection[23].
What is EBV early antigen D AB IgG?
Epstein-Barr Virus Early Antigen D Antibody (IgG) – Primary infection by EBV causes infectious mononucleosis, usually a self-limiting disease in children and young adults. Infection with EBV can cause lymphoproliferative disorders including tumors.
What does high EBV early antigen D AB IgG mean?
Clinical studies have indicated that patients who have chronic active or reactivated EBV infection commonly have elevated levels of IgG-class antibodies to the EA of EBV. IgG antibody specific for the diffuse early antigen of EBV is often found in patients with nasopharyngeal carcinoma (NPC).
What does Epstein-Barr IgG positive mean?
The presence of VCA IgG antibodies indicates that an EBV infection has occurred at some time recently or in the past. The presence of VCA IgM antibodies and the absence of antibodies to EBNA mean that the infection has occurred recently. The presence of antibodies to EBNA means that the infection occurred in the past.
What is EBV early antigen D?
What is the Paul Bunnell blood test?
The Paul Bunnell test is used to screen for Infectious Mononucleosis (IM), which is seen most commonly in adolescents and young adults. IM is caused by the Epstein-Barr virus.
