Diagnóstico laboratorial da Hepatite B

Abstract

The Hepatitis B is considered the major public health problem in several countries, taking into account their morbidity and mortality. Distribution and prevalence are quite heterogeneous around the world, as it depends on their geographic location, socio- economic situations and cultural factors. HBV is transmitted through mucosae and exposure to bodily fluids and sexual transmission is still the most predominant in most areas. The carriers of the HBV have an increased risk of developing cirrhosis, hepatic carcinoma and decompensated. Its diagnosis is made by serological techniques. We can find nowadays modern laboratory techniques to analyze the viral load, the replication of the infectious agent, and assist in the discovery of new drug formulas. While research on immunization of the disease is not yet definitive, existing vaccines also have been the great helper in the fight against Hepatitis B Virus.
