Through cooperation with research institutions such as Xiamen University, Wantai Biotechnology has undertaken multiple national major infectious disease prevention and control projects, promoting innovation in Hepatitis diagnosis and treatment technology. Wantai Biology has developed a variety of detection products covering five Hepatitis viruses, namely, A, B, C, D and E, including the world's first high-value detection test for Hepatitis B core antibody, the first Chinese double antigen sandwich HCV antibody test, and the Hepatitis E diagnostic test, which has become a new generation of "gold standard" for serological diagnosis in the world. The Hepatitis series products meet the different needs of clinical screening, diagnosis, and treatment monitoring, and provide a one-stop solution for comprehensive screening and viral Hepatitis diagnosis.
