膀胱镜检查的有创性以及尿细胞学检查的有限性使得人们对于寻找移行细胞癌的非创伤性诊断工具越来越有兴趣。近年来 ,Fradet和Lockhart发明了ImmunoCyt检查 ,一种结合了尿细胞学和荧光免疫细胞化学的独创技术。它采用Texas红标记的单克隆抗体 19A2 11检测癌胚抗原的高分子量形 The invasiveness of cystoscopy and the limited availability of urinary cytology have led to an increasing interest in non-invasive diagnostic tools for finding transitional cell carcinomas. In recent years, Fradet and Lockhart have invented the ImmunoCyt test, an original technique that combines urinary cytology with fluorescent immunocytochemistry. It employs the Texas Red labeled monoclonal antibody 19A211 to detect the high molecular weight form of carcinoembryonic antigen
