Comparison of the complement fixation test and counterelectrophoresis test for the detection of antibodies in Chagas disease.

摘要

Sera from 452 patients and blood donors were tested for antibodies to Tryp-anosoma cruzi. The complement fixation test and a counterelectrophoresis test were used. The results showed that both tests agreed in 92% of the sera. However, the counterelectrophoresis test was not as sensitive as the complement fixation test.
