May support Gp25 antigen evaluation for Chagas serodiagnosis; leaves open prospective validation before blood donor screening adoption.
Does serodiagnosis with purified Gp25 antigen accurately detect Chagas' disease?
Purified Gp25 antigen demonstrates high diagnostic accuracy for Chagas' disease with minimal cross-reactivity, suggesting utility for routine blood donor screening.
Scharfstein et al. (1985) studied this question.
