Hepatitis B is an infectious disease associated with the inflammation of the liver. Hepatitis B infection is caused due to the Hepatitis B virus (HBV) transmitted from one person to other through infectious blood, semen and other body fluids. Hepatitis B infection can be acute and it may develop into chronic infection if not diagnosed and treated at an early stage. Chronically infected Hepatitis B patients eventually develop liver cirrhosis, hepatocellular carcinoma (liver cancer), fulminant hepatitis B (autoimmune disorder) or suffer from liver failure requiring liver transplant and can even result in death. In 2014, out of the 360 Mn people infected with hepatitis B worldwide, around 1 Mn people died of the disease or other complications associated with it. However, there is a significant decrease in incidence of hepatitis B after introduction of hepatitis B vaccine. Diagnosis of HBV is achieved by performing several tests for serological markers of HBV such as HBsAg, anti-HBs antibodies, HBeAg, anti-HBe antibodies and anti-HBV core antibodies. Currently, nucleic acid testing for HBV DNA is used to detect the hepatitis B viral load. The diagnosis of hepatitis B involves collection of blood samples followed by the detection of viral antigens and antibodies in either serum or plasma.
Hepatitis B Diagnostic Test Market: Drivers and Restraints
In vitro diagnostics is the vital market for the hepatitis B diagnostic test as the serological markers from blood are tested outside the body in the laboratory. Increasing prevalence and incidence of hepatitis B worldwide and multitude of available tests are the major drivers for the increasing growth of global hepatitis B diagnostic test market. Increasing public awareness and understanding of viral hepatitis, promotion of wider access to monitoring and screening procedures by several countries as a part of national program and introduction of evidence based policies are anticipated to aid the growth of global hepatitis B...
