A standard counterelectrophoresis method has been used to screen almost 250,000 samples from South Australian and Northern Territory blood donors since 1971. The initial incidence of approximately one hepatitis B antigen positive donor per thousand has diminished as these donors have been excluded from further blood donation. There is a predominance of males in the series, and more of the hepatitis B antigen carriers are in the younger age groups than expected. A higher than expected incidence of hepatitis B antigen positives has been noted in Northern Territory donors. Follow-up of donors found to be hepatitis B antigen positive has shown that the majority remain positive for more than two years without developing overt hepatitis. These individuals may represent a long-term asymptomatic carrier state.
自1971年以来，一种标准的对流免疫电泳方法已被用于筛查来自南澳大利亚和北领地献血者的近25万个样本。随着这些献血者被排除在进一步献血之外，最初每千名献血者中约有一名乙肝抗原阳性者的发生率有所下降。该系列中男性占主导地位，且乙肝抗原携带者在较年轻年龄组中的比例高于预期。北领地献血者中乙肝抗原阳性的发生率高于预期。对被发现乙肝抗原阳性的献血者进行随访发现，大多数人在两年多的时间里一直呈阳性，且未发展为显性肝炎。这些个体可能代表一种长期无症状携带状态。
