## Indications for use
The LIAISON® EA IgG assay uses chemiluminescent immunoassay (CLIA) technology on the LIAISON® Analyzer family* for the qualitative determination of specific IgG antibodies to Epstein-Barr virus (EBV) early antigen-diffuse [EA(D)] in human serum. This assay uses a 47-kDa recombinant antigen expressed in E. coli DH-1 cells. When performed in conjunction with other EBV markers, this assay can be used as an aid in the clinical laboratory diagnosis of Epstein-Barr Viral Syndrome in patients with signs and symptoms of EBV infection such as infectious mononucleosis. The DiaSorin LIAISON® EA IgG Serum Control Set is intended for use as assayed quality control samples to monitor the performance of the LIAISON® EA IgG assay on the LIAISON® Analyzer family*. The performance characteristics of the LIAISON® EA IgG controls have not been established for any other assay or instrument platforms different from the LIAISON® and LIAISON® XL. *(LIAISON® and LIAISON® XL)
