An immunoglobulin A (IgA) enzyme-linked immunosorbent assay was developed and compared with the radioimmunoprecipitation test in determinations of IgA antibodies to Mycoplasma pneumoniae. Of 45 nasal secretions obtained from infected volunteers, 42 (93.4%) were positive and 2 (4.4%) were negative in both tests. The IgA enzyme-linked immunosorbent assay is at least as sensitive as the IgA radioimmunoprecipitation test but is simpler and safer and should therefore be preferred.
开发了一种免疫球蛋白A(IgA)酶联免疫吸附测定法,并将其与放射免疫沉淀试验在肺炎支原体IgA抗体测定中进行比较。在从感染志愿者获得的45份鼻分泌物中,两种检测方法均呈阳性的有42份(93.4%),呈阴性的有2份(4.4%)。IgA酶联免疫吸附测定法至少与IgA放射免疫沉淀试验一样灵敏,但更简便、安全,因此应优先选用。
