0050235: Epstein-Barr Virus Antibody to Viral Capsid Antigen, IgG

Test Mnemonic: EBV G
Methodology: Enzyme-Linked Immunosorbent Assay

Performed: Tue-Sat

Reported: Within 24 hours

Specimen Required:  
Collect: One 4 mL SST.

Transport: 0.5 mL serum at 2-8°C. (Min: 0.2 mL)  Submit specimen in an ARUP Standard Transport Tube.

Pediatric Collection/Transport: 0.1 mL serum at 2-8°C.

Remarks: Separate serum from cells ASAP. Acute and convalescent specimens must be labeled as such; parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Please mark specimen plainly as "acute" or "convalescent."

Unacceptable Conditions: Contaminated or heat-inactivated specimens.

Stability: After separation from cells: Ambient: 2 days; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Reference Interval:
0.90 IV or less: Negative - No significant level of detectable IgG antibody to EBV viral capsid antigen.
0.91-0.99 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.00 IV or greater: Positive - IgG antibody to EBV viral capsid antigen detected, which may indicate a current or past EBV infection.

Note:
EBV IgG values obtained with different manufacturers' assay methods may not be used interchangeably.  The magnitude of the reported EBV IgG level cannot be correlated to an endpoint titer.

CPT Code(s):
