A study was carried out on the risk of contamination with viral hepatitis B for the personnel of the clinical laboratories who handle blood samples with HB Ag and HB Ac, collected from the patients. Of the total 1945 blood samples collected from 639 adult patients, 74 were serologically positive (3.8%) of which 39 HB Ag carriers (2%) and 35 HB Ac carriers (1.8%). Although these proportions are close to those found in the normal population the risk of contamination of the laboratory personnel is greater owing to the direct contact with the pathologic product and the impossibility of recognizing the HB Ag and Ac positive samples before testing. The risk may be lowered by strict compliance with the general rules of hygiene, by avoiding especially any microtraumas of the hands, by automatic pipetting of the sera and reagents and the use of sterilized materials (particularly in haematologic and biochemical laboratories.
对处理从患者采集的含乙肝表面抗原（HB Ag）和乙肝核心抗体（HB Ac）血液样本的临床实验室人员感染乙型病毒性肝炎的风险进行了一项研究。从639名成年患者采集的总共1945份血液样本中，74份血清学呈阳性（3.8%），其中39份为HB Ag携带者（2%），35份为HB Ac携带者（1.8%）。尽管这些比例与正常人群中的比例相近，但由于实验室人员直接接触病理产物且在检测前无法识别HB Ag和Ac阳性样本，其感染风险更高。通过严格遵守一般卫生规则、尤其避免手部任何微小创伤、自动吸取血清和试剂以及使用消毒材料（特别是在血液学和生化实验室），可降低风险。
