Incorporating species-specific anti-immunoglobulin G (IgG) serum into the hemagglutination-inhibition (HI) test for influenza markedly increased sensitivity without loss of specificity. The effectiveness of anti-IgG serum for augmenting antibody titers may be influenced by the variable potency of commercial anti-IgG preparations. Maximal enhancement of HI titers was achieved when anti-IgG serum and virus-antiserum mixtures were incubated at 23 C for 10 min. Precision and reproducibility of the test were within acceptable limits. Other conditions likely to affect the test were investigated.
将种属特异性抗免疫球蛋白G(IgG)血清加入流感血凝抑制(HI)试验中,可显著提高敏感性且不失特异性。商业抗IgG制剂效力的差异可能会影响抗IgG血清提高抗体滴度的效果。当抗IgG血清与病毒抗血清混合物在23℃孵育10分钟时,HI滴度可实现最大增强。该试验的精密度和可重复性在可接受范围内。还对其他可能影响该试验的条件进行了研究。
