During a measles outbreak, 283 serum specimens from 221 suspected cases of measles were tested by immunofluorescence and enzyme immunoassay for the presence of measles-specific immunoglobulin M (IgM) antibodies by using commercially available reagents. There was 97% agreement between the two assays; thus, the choice of the method for diagnostic testing is a matter of convenience and experience. In all 62 cases of measles from which a single blood sample was available, measles IgM-specific antibodies were detectable by both methods. Fifty percent of the 62 cases were positive within 3 days after onset of the rash. This increased to 91% 10 days after onset of the rash.
在一次麻疹疫情期间,使用市售试剂通过免疫荧光法和酶免疫法对来自221例疑似麻疹病例的283份血清标本进行检测,以确定是否存在麻疹特异性免疫球蛋白M(IgM)抗体。两种检测方法的一致性为97%;因此,选择诊断检测方法是便利性和经验的问题。在所有62例仅提供了一份血样的麻疹病例中,两种方法均检测到了麻疹IgM特异性抗体。62例病例中有50%在出疹后3天内呈阳性。出疹后10天,这一比例增至91%。
