Abstract:
Objective To explore the clinical application of determination of troponin I(cTnI) by enzyme linked fluorescent(EL-FA) method .Methods The concentration of cTnI in serum was detected by chemiluminescence immunoassay(CLIA) method and ELFA method .The precision test ,linear test ,recovery test and interference test were done on ELFA method .The correlation analy-sis was done on the results of cTnI detected by ELFA method and CLIA method .Results Determination of the concentration of cTnI by ELFA method ,the intraassay coefficient of variation(CV) of high(30 .00 μg/L cTnI) and low (0 .12 μg/L cTnI) values were 2 .81% and 1 .62% ,the interassay CV were 5 .67% and 3 .52% .Reliable detection range detection of ELFA method was 0 .00-30 .00 μg/L .When the total bilirubin concentration less than 450μmol/L ,hemoglobin concentration less than 1 .5 g/L ,three glycerol concentration less than 7 .0 mmol/L ,the ELFA method for the determination of cTnI was without interference .Determina-tion of the concentration of cTnI had a good correlation between ELFA method and CLIA method(r=0 .971) .Conclusion The EL-FA method has good precision ,recovery and linear range ,and has a good correlation with the CLIA method ,and the ELFA method is rapid and convenient ,suitable for the emergency inspection ,can satisfy the clinical requirements .
