我们采用对流免疫电泳和琼脂双扩散两法,对我地KG83份人血清及105份动物血清进行了乙型肝炎抗原的检测。 683份人血清中,社员212人,阳性21人(9.9％),炊事员83人,阳性3人(3.6％),均为健康带病毒者,值得注意;其他工种人员388人,阳性19人(4.9％)。对其中159人取血2次(间隔30天),双阳性12人,第1次单阳性4人,第2次单阳性2人,漏检率分别为2.5％和1.3％。对流免疫电泳和琼脂双扩散两法相 We used convective immunoelectrophoresis and agar double diffusion two methods, my KG83 human serum and 105 animal serum hepatitis B antigen detection. Of the 683 human serum samples, 212 were members, 21 were positive (9.9%), 83 were cooks, and 3 were positive (3.6%), all of whom were noted for their health. There were 388 other types of workers and 19 were positive (4.9%). Among them, 159 were taken blood twice (30 days apart), double positive 12, the first single positive 4, the second single positive 2, the missed detection rates were 2.5% and 1.3%.
