OTERO, William; PARGA, Julián  and  GASTELBONDO, Johanna. Serology of hepatitis B virus: multiple scenarios and multiple exams. Rev Col Gastroenterol [online]. 2018, vol.33, n.4, pp.411-422. ISSN 0120-9957.  https://doi.org/10.22516/25007440.327.

Hepatitis B virus (HBV) has an enormous global impact. Despite the availability of a vaccine, two billion people have been acutely infected. Of these, 240 million remain chronically infected. The infection has different forms of presentation including acute infections, chronic infections, hidden infections, and reactivation when there is immunosuppression. Similarly, there are very sensitive markers such as anti-core, but a positive test can have different meanings. This recently described antigen which is related to the core antigen is an emerging marker that could replace viral DNA. In this review we discuss the laboratory tests necessary for diagnosing the various scenarios of the infection.

Keywords : B virus; hidden infection; anti-core; reactivation.
