Epstein-Barr virus (EBV)
To help diagnose infectious mononucleosis (mono); to distinguish between an Epstein-Barr virus (EBV) infection and another illness with similar symptoms.
Please refer to this interpretation chart:
| VCA IgG | VCA IgM | EBNA IgG | Interpretation |
| Negative | Negative | Negative | No previous exposure |
| Positive | Positive | Negative | Recent infection |
| Positive | Negative | Positive | Past infection |
| Positive | Negative | Negative | See note* |
| Positive | Positive | Positive | Past infection |
Note:
*Results indicate infection with EBV at some time (VCA IgG positive). However, the time of the infection cannot be predicted (ie, recent or past) since antibodies to EBNA usually develop after primary infection (recent) or, alternatively, approximately 5% to 10% of patients with EBV never develop antibodies to EBNA (past).
EBNA Ab/IgG
Optimal range: 0 - 18 U/mL
The EBV (Epstein Barr) Nuclear Antigen Antibodies, IgG test looks for a type of antibody which the body typically develops in response to Epstein-Barr Virus.
EBNA antibodies usually appear 2-4 months after infection and persist for the life of the person.
This test is usually performed to establish a past infection with EBV.
LEARN MOREEBV Ab VCA, IgG
Optimal range: 0 - 18 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.
LEARN MOREEBV Ab VCA, IgM
Optimal range: 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.
LEARN MOREEBV CAPSID Ag.ab/IgG
Optimal range: 0 - 18 U/mL
EBV CAPSID Ag.ab/IgG is an antibody (protein) that is produced by the body in an immune response to an Epstein-Barr virus antigen.
LEARN MOREEBV CAPSID Ag.Ab/IgM
Optimal range: 0 - 36 U/mL
EBV CAPSID Ag.Ab/IgM is an antibody (protein) that is produced by the body in an immune response to an Epstein-Barr virus antigen.
LEARN MOREEBV EARLY Ag.Ab
Optimal range: 0 - 9 U/mL
Aid in the diagnosis of acute EBV (infectious mononucleosis) and EBV reactivation in conjunction with other serologic tests. The appearance of IgG antibodies to Early antigen-diffuse [EA(D)] is generally associated with the primary (acute) stage of EBV infection. For most individuals these antibodies are transient and are often undetectable after 6 months.

LEARN MOREEBV Nuclear Antigen Ab, IgG
Optimal range: 0 - 17.9 U/mL
The EBV (Epstein Barr) Nuclear Antigen Antibodies, IgG test looks for a type of antibody which the body typically develops in response to Epstein-Barr Virus.
EBNA antibodies usually appear 2-4 months after infection and persist for the life of the person. This test is usually performed to establish a past infection with EBV.
LEARN MOREEpstein Barr Virus (EBNA) AB (IGG)
Optimal range: 0 - 0.9 index
The EBV (Epstein Barr) Nuclear Antigen Antibodies, IgG test looks for a type of antibody which the body typically develops in response to Epstein-Barr Virus.
EBNA antibodies usually appear 2-4 months after infection and persist for the life of the person.
This test is usually performed to establish a past infection with EBV.
LEARN MOREEpstein Barr Virus VCA AB (IGG)
Optimal range: 0 - 0.9 index
EBV-VCA, IgG is an antibody (protein) that is produced by the body in an immune response to an Epstein-Barr virus antigen.
LEARN MOREEpstein Barr Virus VCA AB (IGM)
Optimal range: 0 - 0.9 index
EBV-VCA, IgM is an antibody (protein) that is produced by the body in an immune response to an Epstein-Barr virus antigen.
LEARN MOREMonospot Heterophile antibody
Optimal range: 0 - 0.001 index
The mononuclear spot test or monospot test, a form of the heterophile antibody test, is a rapid test for infectious mononucleosis due to Epstein–Barr virus (EBV).
