The performance of a direct agglutination test for the detection of toxoplasma specific IgG immunoglobulin was compared with that ofthe latex agglutination test. The direct agglutination test was less sensitive but more specific than the latex agglutination test. Quantitative results were not directly comparable, reflecting the different antibody profiles detected in each assay. The direct aggl...

direct agglutination test (dat) is a sensitive and simple method, which is applicable in field and unequipped laboratories. in order to evaluate dat in the diagnosis of toxoplasma infections, the antigen was prepared in the protozoology unit, school of public health and it was used in the following studies. a- 251 serum samples collected from suspected toxoplasmosis out-patients were examined f...

background: new cases of visceral leishmaniasis (vl) have been reported recently in some parts of mazandaran province, north of iran where the first human case of  vl was reported in 1949. this study aimed to determine the present status of leishmania infantum infection among humans and domestic dogs using serological and molecular methods in central parts of mazandaran province. methods: in th...

The Coombs test (Coombs, Mourant, and Race, 1945a, 1945b, 1946) has become popular as a sensitive and reliable method of detecting incomplete antibodies. The essential reagent is the serum of an animal (usually a rabbit) which has been immunized with human globulin. Potent rabbit sera sometimes show a prozone phenomenon (Wootton, 1950; Van Loghem, Kresner, Coombs, and Fulton Roberts, 1950). The...

The BrucellaCapt test is an immunocapture agglutination test suggested as a possible substitute for the Coombs test in the diagnosis of human brucellosis. Here it is compared with classical tests using 321 samples from 48 patients with brucellosis (6.9 +/- 1.7 samples per patient), including 20 patients with focal disease and 8 patients with a total of 9 relapse episodes (mean follow-up, 18 mon...

OBJECTIVE To compare the performance of the direct agglutination test and rK39 dipstick for the diagnosis of visceral leishmaniasis. DATA SOURCES Medline, citation tracking, January 1986 to December 2004. Selection criteria Original studies evaluating the direct agglutination test or the rK39 dipstick with clinical visceral leishmaniasis as target condition; adequate reference classification;...

A comparison of the direct agglutination test and the indirect hemagglutination test for the detection of blood serum antibodies to Escherichia coli organisms indicated that these serological tests were comparable. In some instances the indirect hemagglutination test provided higher endpoint readings. Preparation of the antigens for the indirect hemagglutination test was more time consuming tha...
