    Journal: Clin Diagn Lab Immunol; 2001 Sep; 8(5):1024-7. PubMed ID: 11527823.
    Abstract:
    The reactivities of sera from chronic chagasic patients against the trypomastigote excreted-secreted antigens (TESA) of Trypanosoma cruzi strains with different biodemes were analyzed by TESA-blot and TESA-enzyme-linked immunosorbent assay (ELISA). Although both tests presented high sensitivity and specificity, TESA-ELISA is more appropriate for screening a larger number of samples.
