What is anti EBV VCA IgG?

Anti-EBV (VCA) IgG is an ELISA-based, automated, in-vitro test system for the quantitative determination of IgG antibodies against Epstein-Barr virus viral capsid antigen (VCA) in human serum or plasma.

What is EBV early ag?

EBV Early Antigen Blood Test The EBV Early Antigen (EA) Antibodies IgG test looks for a type of antibody which the body typically develops in response to Epstein-Barr Virus. These antibodies usually develop in the acute phase of infection and fall below detectable levels after 3-6 months.

What is EBV?

The Epstein-Barr virus causes infectious mononucleosis and other illnesses. It’s spread primarily through saliva by kissing or sharing food and utensils. Many people are infected with EBV as children and don’t have any symptoms. Mononucleosis occurs mostly in teens and adults.

What is a high VCA IgG level?

What does it mean if your EBV Ab VCA, IgG result is too high? Presence of detectable VCA IgI antibodies. A positive result indicates current or past exposure. The EBV-VCA IgG antibody emerges during acute infection with the highest level at 2 to 4 weeks, then drops slightly, stabilizes, and is present for life.

How long does EBV VCA IgG stay positive?

Viral capsid antigen (VCA) Anti-VCA IgM appears early in EBV infection and usually disappears within four to six weeks. Anti-VCA IgG appears in the acute phase of EBV infection, peaks at two to four weeks after onset, declines slightly then persists for the rest of a person’s life.

What is normal EBV level?

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.

What is a normal EBV level?

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.

How do you read EBV results?

Interpretation. The test has 3 components: viral capsid antigen (VCA) IgG, VCA IgM, and Epstein-Barr nuclear antigen (EBNA). 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.

What causes EBV?

Transmission. EBV spreads most commonly through bodily fluids, especially saliva. However, EBV can also spread through blood and semen during sexual contact, blood transfusions, and organ transplantations. EBV can be spread by using objects, such as a toothbrush or drinking glass, that an infected person recently used.

If the individual also has symptoms associated with mono, then it is most likely that the person will be diagnosed with mono, even if the mono test was negative.

How long does EBV IgM stay positive?

Anti-VCA IgM appears early in EBV infection and usually disappears within four to six weeks.

Can chronic EBV be cured?

The only proven effective treatment for the disease is hematopoietic stem cell transplantation. Current studies to find a cause of this disease focus on immune defects and genetic abnormalities associated with the disease.

What is normal range for EBV?

According to the manufacturer’s recommendations, EBNA-1 IgG levels <5 U/ml were considered negative, levels between 5–20 U/ml were considered equivocal, and levels ≥20 U/ml were considered positive.

How long does EBV last?

People who get symptoms from EBV infection, usually teenagers or adults, get better in two to four weeks. However, some people may feel fatigued for several weeks or even months.
