目的：应用胶体金免疫层析法制备检测全血或血清样本中心肌型脂肪酸结合蛋白（ H-FABP ）的检测试纸条，用于急性心肌梗塞（ AMI）的早期辅助诊断。方法采用柠檬酸三钠还原法制备胶体金，标记鼠抗心肌型脂肪酸结合蛋白单克隆抗体，喷于玻璃纤维膜上制成胶体金结合物垫，将另一株鼠抗心肌型脂肪酸结合蛋白单克隆抗体和抗鼠二抗分别包被检测线和质控线，组装成试纸条进行灵敏性、特异性、精密性、稳定性及临床样品检测。结果该试纸条的检测灵敏度为10 ng/mL，15 min内可判定结果；与肌钙蛋白I、C反应蛋白、肌酸激酶、人心肌肌红蛋白无交叉反应。检测240份临床标本，与临床诊断结果进行配对分析，阳性符合率95．83％、阴性符合率100％、总符合率97．92％。结论制备的H-FABP检测试纸条有良好的灵敏性、特异性，可用于早期AMI的辅助诊断。

Objective To develop the detection kit of human heart-type fatty acid binding protein ( H-FABP ) from the whole blood or serum samples using colloidal gold immunochromatography technology , for the early diagnosis of acute myo-cardial infarction ( AMI) .Methods The colloidal gold was obtained by trisodium citrate reduction method .Colloidal gold particles labelled with monoclonal antibody of H-FABP were used as the detector reagent and coated on some glass fiber and dried.The other monoclonal antibody of H-FABP and purified anti-mouse IgG were blotted on the test line and control re-gions of nitrocellulose membrane .Then the strip was finished and the detection sensitivity ,specificity, precision,stability were measured ,and clinical samples were done as well .Results The detection sensitivity of this method was 10 ng/mL and the analysis process can be completed within 15 min.There are no cross reactions with cardiac troponin I ,C-reactive protein,human creatine kinase MB and myocardial myoglobin .To compare the agreement of positivity/negativity between clinical samples and results with 240 cases.we found that the positive coincidence rate is 95.83% and negative coinci-dence rate is 100%, and the total compliance rate is 97.92%.Conclusions The test strip for the rapid detection of H-FABP have been made with good sensitivity and specificity , can be used for early diagnosis of AMI .
