In the microimmunofluorescence test for measuring immunoglobulin A (IgA) antibodies against Chlamydia pneumoniae, removal of interfering IgG antibodies made IgA antibody reactivity patterns in 952 serum samples easier to interpret, prozone effects disappeared, and titers increased, especially in the sera with high IgG titers. IgA rheumatoid factors did not interfere in the assay.
在用于检测抗肺炎衣原体免疫球蛋白A(IgA)抗体的微量免疫荧光试验中,去除干扰性IgG抗体后,952份血清样本中的IgA抗体反应模式更易于解读,前带效应消失,且滴度升高,尤其是在IgG滴度较高的血清中。IgA类风湿因子不干扰该检测。
