[Laboratory diagnosis of Epstein-Barr virus infection].
Laboratory confirmation of EBV infection requires proper methods and schema of investigation adequate to aim of diagnostic procedure. In paper the results of routine diagnostic tests of EBV infection performed in Department of Virology NIH in 2005-2006 years was included and also, evaluation of usefulness of different laboratory methods was done. Based on results of ELISA tests 10,7% routine investigated subjects was classified as primary EBV infection, 20,1% was seronegative, 7,4% was classified as reactivation of latent infection and serological markers in 45,6% subjects pointed past EBV infection. Positive result of PCR method was obtain in 11,2% samples subjected of routine laboratory investigation. Comparison of specific and non-specific serological methods results (ELISA versus tests of heterophile antibodies) showed the high percentage of false negative results in children tested by non-specific tests. PCR results in serum samples from patients with primary infection (confirmed by serological tests) were positive in 15% cases only. Based on analyzed results it could be stated that reliable confirmation of infectious mononucleosis, as primary EBV infection, is detection of specific IgM antibodies and in case of heterophile antibodies tests the possibility of false negative results, mainly in children, must be taken into account. The most proper samples for PCR method are whole blood, sections of tissue or cells from swabs.
