The direct agglutination technique for chagasic infection diagnosis is easy to performand inexpensive. It has good sensitivity and specificity when used in conjunction
with other serological and/or parasitological techniques. It has been replaced with
other reactions with faster results and easiness to read (i.e. immunoenzymatic
assay (ELISA) and indirect hemagglutination). Currently it is difficult to obtain
commercial kits. In the present paper we present a series of cases that show the
usefulness of the direct agglutination test to early determine acute and/or congenital
infection and to differentiate acute from chronic infections.
