Hepatitis B in vitro diagnostic market is forecasted to grow from $991.2m in 2023 to over $1.1bn in 2030, as per a GlobalData market model. The market is expected to grow at a compound annual growth rate (CAGR) of 2.16%.

Hepatitis B is an infection of the liver caused by the hepatitis B virus (HBV). It can spread through contact with infected body fluids like blood, saliva, vaginal fluids, and semen. It can also be passed from a mother to her baby, through the placenta.

The World Health Organization (WHO) has identified hepatitis B as a major global health problem, with the highest infection rates in the western Pacific and African regions. Hepatitis B is a preventable disease with the neonatal hepatitis B vaccine. Hepatitis B can only be diagnosed through in vitro testing as it is clinically indistinguishable from other hepatitis.

As the Elecsys HBeAg quant test provides both qualitative and quantitative analysis, it is expected to improve workflow and reduce complexity for lab personnel. The quantitative analysis provided by the test can also be used to design a personalised treatment for hepatitis B patients.
