May aid in the diagnosis of acute Epstein-Barr virus (EBV) infection and EBV reactivation in conjunction with other serologic studies. Molecular tests are preferred to detect EBV reactivation. Not a stand-alone test.
- Patient Preparation
- Collect
- Serum Separator Tube (SST).
- Specimen Preparation
- Allow specimen to clot completely at room temperature. Separate serum from cells ASAP or within 2 hours of collection. Transfer 2 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens.
- Storage/Transport Temperature
- Refrigerated.
- Unacceptable Conditions
- Contaminated, heat-inactivated or grossly hemolyzed specimens.
- Remarks
- Label specimens plainly as "acute" or "convalescent."
- Stability
- After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
8.9 U/mL or less: Not Detected
9.0-10.9 U/mL: Indeterminate - Repeat testing in 10-14 days may be helpful.
11.0 U/mL or greater: Detected
