乙肝病毒及其抗原一发现，布伦·伯格和他的研究小组就设计实验，以便在输血前对献血者进行鉴别。因为输血经常传播乙肝这种传染病。
Once the virus and its antigen were found, Dr Blumberg and his team devised tests for it, so that donors could be screened before giving the blood that often transmitted the infection.
方法用酶联免疫吸附试验对982例乙肝患者血清标志物和乙肝病毒前S2抗原进行检测；并用荧光定量PCR法对其进行HBV-DNA检测。
Methods Hepatitis B serum markers and Pre-S2 antigens were tested by enzyme-linked immunosorbent assay and HBV DNA was detected by fluorescent quantitative-PCR in 982 hepatitis B patients.
