The serum levels of IgA, IgG and IgM were determined by the single radial immunodiffusion method in 86 patients with acute viral hepatitis serologically differentiated by radioimmunoassays. The levels of IgA and IgG were similar in patients with hepatitis A, B and non-A, non-B, while differences in IgM levels were observed between the three groups. The hepatitis non-A, non-B group had significantly lower levels of IgM than both the hepatitis A and hepatitis B group, a finding which may be diagnostically useful if hepatitis A serology fails.
采用单向辐射免疫扩散法测定了86例经放射免疫分析法血清学鉴别诊断的急性病毒性肝炎患者的血清IgA、IgG和IgM水平。甲型、乙型和非甲非乙型肝炎患者的IgA和IgG水平相似，但三组之间的IgM水平存在差异。非甲非乙型肝炎组的IgM水平显著低于甲型和乙型肝炎组，这一发现如果甲型肝炎血清学检测失败可能具有诊断价值。
