Abstract

The ELISA screening detection of anti-EBNA-1 IgG in the absence of VCA IgG and IgM is rare but may lead to doubts in interpretation.We used immunoblotting to characterise 23 serum samples with “isolated EBNA-1 IgG” upon ELISA screening, and found that all showed VCA anti-p23 and 13 (56.6%) also showed VCA anti-p18 antibodies. It therefore seems impossible for a sample to show anti-EBNA-1 IgG without anti-VCA IgG antibodies. Furthermore, although anti-p18 antibodies are thought to develop later and therefore considered to be markers of past infection, about 1% of all previously infected EBNA-1 IgG-positive patients do not have them.

PlumX Metrics

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
