Test Details
Methodology
Chemiluminescent immunoassay (CLIA)
Result Turnaround Time
1 - 2 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Test Includes
Epstein-Barr virus (EBV) early antigen antibody, IgG; Epstein-Barr virus (EBV) antibody to viral capsid antigen, IgG
Use
Aid in the diagnosis of acute EBV (infectious mononucleosis) and EBV reactivation in conjunction with other serologic tests. The appearance of IgG antibodies to EA(D) is generally associated with the primary (acute) stage of EBV infection. For most individuals, EA(D) IgG antibodies are transient and are ogten undetectable after 6 months while VCA IgG antibodies persist indefinitely.
Limitations
The results for this test are not by themselves diagnostic and should be considered in association with other clinical data and patient symptoms.
This test is intended for qualitative determination only. The numeric value of the final result above the cutoff is not indicative of the amount of EBV-EA or EBV-VCA antibodies.
