Pruba de anglutinación indirecta de partículas de gelatina, un medio simple y sensible para el serodiagnóstico de la de la enfermedad de Chagas / Annual Reports 1992 / The gelatine praticle indirect agglutination test, a means of simple and sensitive serodiagnósis of Chagas' disease

An indirect agglutination test using Trypanosoma cruzi antigen-coated gelatin particles was employed to Trypanosomiasis in Paraguay. Results with this test were quite comparable to those obtained with enzyme-linked immusorbent assay (Elisa). Furthermore, nonspecific reaction to the gelatin particles alone was not found in either acute or chronic infection. This method is more convenient than the ELISA, since the antigen-conjugate particles are stable for at least 1 year at 47 ºC and the test itself is short and simple to perform and does not require specialized equipment
