IgG class antibodies to the Epstein-Barr virus nuclear antigen (EB NA IgG, Epstein-Barr Virus Nuclear Antigen IgG, EBNA IgG)

No special training is required. It is recommended to take blood no earlier than 4 hours after the last meal.

In which cases are IgG antibodies to the Epstein-Barr virus nuclear antigen analyzed: laboratory confirmation of the diagnosis in case of clinical suspicion of acute infectious mononucleosis; assessment of the stage of the current infection; diagnosis of lymphoproliferative and oncological diseases associated with the Epstein-Barr virus.

The interpretation of the research results contains information for the attending physician and is not a diagnosis. The information in this section cannot be used for self-diagnosis and self-medication. An accurate diagnosis is made by a doctor using both the results of this examination and the necessary information from other sources: anamnesis, results of other examinations, etc. Units of measurement: Units/ml. Type of response output: quantitative Reference values <3.5 – negative 3.5 – 5 – doubtful >5 positive Interpretation of the results of a study on IgG class antibodies to the Epstein-Barr virus nuclear antigen Positively Infection with Epstein-Barr virus in the past (more than six months ago). Reactivation of the virus. Chronic active infection with Epstein-Barr virus. Negative Absence of infection. The incubation period. Early stages of infection.
