|
Methodology: Enzyme-Linked Immunosorbent Assay
Performed: Tue-Sat Reported: 1-2 days |
| 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.

0.90 IV or less: Negative - No significant level of detectable IgM 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 - IgM antibody to EBV viral capsid antigen detected, which may indicate a current or recent EBV infection. |

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