Abstract:
Objective To investigate the effect of two different detection methods of reagent kits on blood concentration of Tacrolimus in liver transplantation .Methods 81 cases of liver transplantation patients received Tacrolimus testing in Zhoushan Hospital from February 2013 to August 2016 were selected, fasting venous blood of upper limb were collected 12h after treatment, blood concentrations of Tacrolimus in whole blood samples were detected by Enzyme linked immunosorbent assay ( ELISA) kit and Enzyme enhanced immunoassay ( EMIT) kit respectively , the results of the two methods were observed and compared .Results The intra day and inter day precision and accuracy of ELISA method were good , RSD <5%, in the low concentration range , the precision of detection was slightly worse; the intraday and inter day precision and accuracy of ELISA method were good , RSD <5%, in the low concentration range , the precision of detection was slightly worse; the Tacrolimus blood concentration measured by ELISA (5.19 ±0.73) μg/L test kit was significantly lower than that measured by EMIT kit (8.29 ±1.14) μg/L, the difference was statistically significant (P<0.05); correlation coefficient of the detection results of two kinds of reagent kit was r =0.9176, the detection results were positively related; the determination results of ELISA kit ( 1.116 ±0.125 ) μg/L were obviously lower than that of EMIT kit (1.507 ±0.201) μg/L when Tacrolimus blood concentration <2g/L, with significant difference (P<0.05).Conclusion ELISA detection kit and EMIT kit can be used to monitor the blood concentration of Tacrolimus in liver transplantation patients , and the correlation was good, but the blood concentrations of Tacrolimus were significantly different between the two kits , need to establish their own of therapeutic window to judge,the test results can not be replaced with each other .
