Research Progress on Interference of Endogenous Factors in Detection of Serum Cardiac Troponin I by Sandwich Antibody Immunoassay and Its Solutions
心肌肌钙蛋白I(cardiac troponin I,cTnI)是临床上诊断心肌损伤的首选血清学标志物.cTnI检测基于抗体夹心免疫法,不同检测试剂中检测和捕获抗体所针对的cTnI抗原表位不一致,易造成cTnI检测结果的异质性.内源性干扰因素如cTnI自身抗体、异嗜性抗体、类风湿因子等可严重的干扰cTnI检测结果,影响临床上对心肌损伤类疾病的诊断、治疗及预后判断.该文就cTnI的抗体夹心免疫检测和内源性因素对cTnI检测的干扰及解决方案等方面研究进展作一综述,为临床上鉴别诊断cTnI异常检测结果提供理论依据.
Cardial troponin I(cTnI)is the preferred serological marker for the diagnosis of myocardial injury.cTnI detection is based on antibody sandwich immunoassay.The epitopes of cTnI antigen targeted by detecting and capturing antibodies in different detection reagents are inconsistent,which easily leads to the heterogeneity of cTnI detection results.Endogenous interfering factors such as cTnI autoantibody,heterophile antibody,rheumatoid factor,ect,which can seriously interfere with the results of cTnI detection,and affecting the clinical diagnosis,treatment and prognosis of myocardial injury diseases.In this paper,the research progress of antibody sandwich immunoassay for cTnI and interference of endogenous factors on cTnI detection and solutions are reviewed to provide theoretical basis for differential diagnosis of abnormal cTnI detection results in clinical practice.
