免疫荧光试验(Immunofluores—cent test)又叫免疫荧光抗体试验(I—mmunofluorescent antibody test,IFA),是一种把免疫学的特异性和敏感性与显微镜形态学的精确性结合起来的血清学诊断技术。就是将荧光色素与特异性抗体(或抗原但少用)以化学方法相结合,制成荧光标记抗体,而抗体的免疫特异性不受影响。然后将此荧光标记抗体,在一定条件下染色标本,用荧光显微镜观察。如标本中的抗原能与荧光标记抗体发
The Immunofluorescent-cent test, also known as the I-mmunofluorescent antibody test (IFA), is a serological diagnosis that combines the specificity and sensitivity of immunology with the accuracy of microscopic morphology technology. Is the fluorescent pigment and specific antibodies (or antigen but less used) chemically combined to make fluorescent labeled antibody, and the immune specificity of the antibody is not affected. The fluorescent labeled antibody was then stained under certain conditions and observed under a fluorescence microscope. Such as specimens of antigens and fluorescent labeled antibody hair
