Human EBV EA IgM ELISA kit is a procedure for analysing in-vitro quantitative levels of human IgM antibodies to the Epstein–Barr virus early antigen (EBV EA IgM) using samples of plasma or serum. This assay has a minimum analytical sensitivity limit of 1.1 U/ml.
Epstein–Barr virus (EBV) can also be referred to as human herpesvirus 4 (HHV-4) and it belongs to the family of viruses known as herpes. EBV is responsible for causing infectious mononucleosis, an illness which is associated with sore throat, fever, swollen lymph nodes and sometimes enlarged spleen. This virus is able to spread through many commonly bodily fluids, especially saliva. It is also able to spread through blood and semen, organ transplantations and blood transfusions. A large number of these viral infections have been linked to autoimmune diseases for example Sjögren’s syndrome, multiple sclerosis, dermatomyositis, systemic lupus erythematosus and rheumatoid arthritis. EBV Early antigen (EBV EA) can be associated to a number of different acute phase illness, however, after 3-6 months the levels become undetectable.
