Abstract:

The prevalence of myocardial injury diseases is increasing rapidly in the world. Monitoring and accurate diagnosis of myocardial injury diseases is essential to reduce disease hazard. Currently,the biomarkers in myocardial injury mainly belong to peptides and proteins,typically expressed lower than 10-8 g/L. Immunoassay-based techniques enable a sensitive determination level for low abundant biomarkers,followed by developed as the dominant method. However,some inherent problems have also existed among current clinical immunoassays regarding testing accuracy. To illustrate testing barriers,this review proposes and summarizes some representative issues that usually interfere with the testing accuracy in B-type natriuretic peptide(BNP) and troponin. Meanwhile,some emerging technologies will be introduced in the context,and then to discuss its application that potential applied in myocardial injury clinical measurement.
