Evaluation of diagnostic efficiency of the new enzyme immunoassay for detection of IgM antibodies to Hepatitis B core antigen

Recently, many studies are available about the detection of viral DNA in sera containing IgM to HBcAg in the absence of HBsAg, which lead to increase the risk of transmission of HBV, what is especially important for blood transfusion and the use of blood products. In this regard, it is important to use highly sensitive ELISA test for detection of IgM against HBcAg which could help to eliminate the risk of transmission of HBV, especially during the «serological window».
