Auckland Hospital laboratory staff were tested on three occasions over a 9 month period for the presence of hepatitis B antigen (HBsAg) and antibody (anti-HBs). Over 20 percent of technical staff were seropositive for one of these markers of hepatitis B virus (HBV) infection, this proportion being significantly higher than that found in new blood donors or in staff from a laboratory not handling blood samples. Asymptomatic infection with the HBV virus, as assessed by seroconversion changes of HBsAg to anti-HBS status, was detected in some staff members. The number of staff positive for HBsAg or anti-HBS increased with both age and length of period of employment in laboratory work. The results indicate that subclinical HBV infections are occurring in laboratory staff and the present procedures in the care and handling of blood specimens may require review and improvement.
在9个月的时间里，奥克兰医院的实验室工作人员接受了三次乙肝抗原（HBsAg）和抗体（抗-HBs）检测。超过20%的技术人员乙肝病毒（HBV）感染的这些标志物之一呈血清学阳性，这一比例显著高于新献血者或未处理血样的实验室工作人员。通过HBsAg向抗-HBs状态的血清转化变化评估，在一些工作人员中检测到无症状的HBV病毒感染。HBsAg或抗-HBs呈阳性的工作人员数量随着年龄和实验室工作年限的增加而增加。结果表明，实验室工作人员中正在发生亚临床HBV感染，目前血液标本的护理和处理程序可能需要审查和改进。
