ABSTRACT
Objective To compare correlation of tolulized red unheated serum test(TRUST),enzyme-linked immunosorbent assay method(ELISA)and treponema pallidum antibody determination.Methods The Positive re- sults were detected by TP-ELISA in recipients before blood transfusion,which were detected in two wells again.If they were positive again,they should be detected by TRUST and TPPA again.Results The positive results by TRUST and TPPA were 18 and 39.The positive correlation of TRUST and TPPA was 40.9%,the positive correla- tion of TRUST and TPPA was 43.6%,the positive correlation of ELISA and TPPA was highest,which was 88.6%.Conclusion The positive correlation of TRUST was lower than ELISA and TPPA,it was proper for obser- vation of therapeutic effect;the positive correlation of ELISA and TPPA was higher,and it was proper for filtering determination of many samples.
