Fibrinogen antigens were measured either with an agglutination inhibition method (using latex particles coated with fibrinogen; Diagen test) or with a direct agglutination technique (using latex particles coated with a mixture of anti-D and anti-E antibodies; Thrombo-Wellcotest). Both methods were compared with the tanned red cell haemagglutination inhibition immunoassay (TRCHII) during progres...

During experiments on the effect of direct electric currents on red cells suspended in saline an unexpected phenomenon was observed. Normal red cells showed agglutination and lysis, but if the red cells had been sensitized by antibodies there was a marked difference in the degree of agglutination and lysis. Samples of red cells which had been treated with " blocking " Rhesus antibody (anti-D an...

The present study was carried out to assess the efficacy of microtiter method of direct antiglobulin test in diagnosis of Immune Mediated Haemolytic Anaemia in Dogs. Two hundred and fifty eight anaemic dogs with pale/icteric mucous membrane were used for the present study. Initial screening of these dogs was done with saline agglutination test. Forty seven dogs were found positive for saline ag...

Sera obtained from 62 patients from four mountain counties in Catalonia (Northeastern Spain), in whom brucellosis had been diagnosed on the basis of clinical evidence and/or personal history, were analyzed using the rose Bengal test, standard serum agglutination test (SAT), Coombs' test, ELISA, and complement fixation. The diagnosis was further confirmed through blood cultures. Clinical evidenc...

Serum antitoxoplasma titres were determined simultaneously by the direct agglutination and the indirect immunofluorescent tests in 52 children aged 2 to 16 years having chronic lymph node enlargement, mainly cervical. Direct agglutination titres were raised (64 to 4096) in 22 children (42%), but rarely in the control groups of children with acute suppurative lymphadenitis, and healthy children,...

Background: Every human being, especially a married couple, wants children. Obstacles to obtaining children are called infertility. One of the Assisted Reproductive Technology (ART) procedures used for treating infertility is intrauterine insemination (IUI), non-invasive procedure with affordable costs. The success IUI influenced by many factors, one which sperm agglutination.
 Objective: ...

This study aimed to evaluate the performance of a fast agglutination screening test (FAST) for serodiagnosis of human Leishmania infantum infection in Iran. FAST is based on the direct agglutination test (DAT) but combines with a higher parasite concentration and is performed with only one serum dilution. The validity of FAST for the detection of L. infantum infection in the field was compared ...
