trans-sialidase inhibition assay, a highly sensitive and specific diagnostic test for Chagas' disease

Clin Diagn Lab Immunol. 2001 Jan;8(1):187-9. doi: 10.1128/CDLI.8.1.187-189.2001.

Abstract

For the diagnosis of Chagas' disease, the trans-sialidase inhibition assay was able to resolve the results for samples with borderline results, to detect as positive 60% of samples that were negative by conventional serology, and to discriminate idiopathic from chagasic megaviscera or cardiopathy. No cross-reaction with sera from patients with other diseases was observed.
