  • EBV Nuclear Antigen IgG (EBNA)
2

Testing for EBV Viral Capsid Antigen IgM (VCA IgM) will be conducted under the following circumstances:

  • Upon request by the ordering physician along with clinical information suggesting a recent/current infection. The following information must be included.
    • symptoms
    • date of onset
  • Children under 5 years of age: the following information must be included.

Preparation Prior to Transport

Label the specimen container with the patient’s full name, date of collection and one other unique identifier such as the patient’s date of birth or Health Card Number. Failure to provide this information may result in rejection or testing delay.

Requisitions and Kit Ordering

Test Frequency and Turnaround Time (TAT)

Epstein Barr Virus serology testing is performed daily Monday to Friday. 

Turnaround time is up to 5 days from receipt by PHO Laboratory.

Reporting

Test Methods

The EBV IgG and IgM tests are performed using the BioPlex 2200 EBV IgG and IgM kit for use with the Bio-Rad BioPlex 2200 System.

It is a Multiplex Flow Immunoassay test intended for the qualitative detection of IgG antibodies to Epstein-Barr Virus Nuclear Antigen-1 (EBV-NA1), Viral Capsid Antigen (EBV VCA), and IgM antibodies to Epstein-Barr Virus Viral Capsid Antigen IgM (EBV VCA IgM) in human serum samples.

The EBV IgG kit is used in conjunction with the EBV IgM kit as an aid in the laboratory diagnosis of infectious mononucleosis (IM).

Assay performance characteristics have not been established for immunocompromised or immunosuppressed patients, cord blood, neonatal specimens, or infants. Assay performance characteristics have not been established for the diagnosis of nasopharyngeal carcinoma, Burkitt’s lymphoma, and other EBV associated lymphomas.

General information

EBV  belongs to the Herpes virus family. Primary EBV  infections occur mostly during adolescence with 95% of the population having been infected by age 40. Reactivation to EBV can occur at later times. EBV has been linked with Burkitt’s lymphoma and Nasopharyngeal Carcinoma.

Monospot/slide testing

Monoslide/ Monospot is not available at PHO laboratory – contact your private /community lab.
