Estimation of sensitivity and specificity of several Trypanosoma cruzi antibody assays in blood donors in Argentina

摘要

BACKGROUNDThe absence of a gold standard test for Trypanosoma cruzi antibodies represents a problem not only for the evaluation of screening tests, but also for appropriate blood donor counseling. The aim of this study was to estimate the sensitivity and specificity of multiple blood donor screening tests for T. cruzi antibodies in Argentina.
