Two Laboratory Detections of Epstein-Barr Virus:A Comparative Analysis / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To compare the effectiveness of two laboratory detections methods of Epstein-Barr virns (EBV). METHODS Immuno-fluorescence technique was applied to detect the serum EBV-specific antibody and EBV-DNA was identified by fluorescence quantitative polymerase chain reaction (FQ-PCR) in 124 children infected with EBV. RESULTS The positive rates of VCA-IgM,VCA-IgG,EA-IgG,EBNA-1-IgG and EB-DNA in various samples of 124 cases were 0,89.5%,23.4%,49.2% and 30.3%,respectively,with 21 cases (16.9%) showing simultaneously positive in EB-DNA and EBNA-1-IgG. CONCLUSIONS The two laboratory detections of EBV share their advantages and disadvantages. FQ-PCR is a method for time-saving,accurate and sensitive detection of EBV-DNA,showing clinical significance in the diagnosis of EBV-associated diseases. It's worthy of clinic application.
