阑尾炎是最常见的需要外科处理的急腹症，也是急诊病人中最易漏诊的，因此最易引起医疗差错。因此，需要一种迅速、准确的诊断方法。放射物标记的抗白细胞单克隆抗体可在注入体内后迅速标记白细胞，而抗体的小片段由于在血内清除快且不易引起免疫反应更适于临床应用。Sulesomab Appendicitis is the most common acute abdomen requiring surgical treatment, and is also the most commonly missed diagnosis among emergency patients, making it most likely to cause medical errors. Therefore, a rapid and accurate diagnostic method is needed. Radiation-labeled anti-leukocyte monoclonal antibodies rapidly label leukocytes after they are injected into the body, whereas small fragments of antibodies are more suitable for clinical use because of their rapid clearance within the blood and their poor immune response.
