When does EBV IgG turn 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].
How do I read my EBV antibody profile?
Presence of VCA IgM antibodies indicates recent primary infection with Epstein-Barr virus (EBV). The presence of VCA IgG antibodies indicates infection sometime in the past. Antibodies to EBNA develop 6 to 8 weeks after primary infection and are detectable for life.
What is a normal EBV-VCA IgM level?
Optimal Result: 0 – 36 U/mL. EBV-VCA, IgM is an antibody (protein) that is produced by the body in an immune response to an Epstein-Barr virus antigen.
What is the relationship between VCA IgG and EBNA-1 IgG?
The presence of VCA IgG and VCA IgM in the absence of EBNA-1 IgG indicates acute infection, and the presence of VCA IgG and EBNA-1 IgG in the absence of VCA IgM is typical of past infection (Table (Table2).2).
What is the optimal result for EBV AB VCA IgM?
EBV Ab VCA, IgM Optimal Result: 0 – 36 U/mL. EBV-VCA, IgM 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.
What is EBV-VCA IgG?
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.
What is the significance of EA (D) IgG in EBV infection?
The presence of EA (D) IgG may help indicate a past infection as approximately 20%-30% of healthy subjects with a history of EBV infection have EA (D) IgG[2,23,25], but nothing can be said in the case of negativity. However, immunoblotting for IgG can solve the problem as it can confirm the real presence of EBNA-1 IgG.
