Is there a definitive test for Epstein-Barr?

The presence of VCA IgM antibodies and the absence of antibodies to EBNA mean that the infection has occurred recently. The presence of antibodies to EBNA means that the infection occurred in the past.

What does EBV PCR positive mean?

Recently, EBV PCR has been added as a diagnostic tool. Positive EBV PCR has been demonstrated in the serum of patients with primary EBV infections and EBV reactivation. Objectives: To compare classical serological diagnosis of primary EBV infection and EBV reactivation with real-time EBV PCR.

Can you have Epstein-Barr without mono?

How accurate is the Monospot test?
