The indirect haemagglutination assay (IHA) is a simple serological test that can be used to detect antibodies raised by humans to Burkholderia pseudomallei, the cause of melioidosis. The IHA is currently the most common test used worldwide to quantify the human antibody response to Burkholderia pseudomallei Glutaraldehyde-fixed sheep erythrocytes (GA-SRBC) were used in the indirect hemagglutination test for the detection of Pasteurella antibody. GA-SRBC were stable for at least 6 months. Heat extract or potassium thiocyanate extract antigens of Pasteurella strains could be adsorbed onto GA-SRBC or tanned GA-SRBC, respectively
The indirect hemagglutination assay (IHA) is the most frequently used serological test to help confirm exposure to the causative organism. However, despite culture-confirmed disease, patients often have a negative IHA result at presentation and occasionally fail to seroconvert in serial testing Hemagglutination. measures the relative concentration of antibody in serum. is expressed as Titer. an indirect assay can also be devised: the antigen is linked to RBC.

The hemagglutination assay or haemagglutination assay (HA) and the hemagglutination inhibition assay (HI or HAI) were developed in 1941-42 by American virologist George Hirst as methods for quantifying the relative concentration of viruses, bacteria, or antibodies.. HA and HI apply the process of hemagglutination, in which sialic acid receptors on the surface of red blood cells (RBCs) bind. The serodiagnostic test most widely used in endemic areas is an indirect hemagglutination (IHA) test, which detects IgM antibodies to crude heat-stable antigens (probably predominantly LPS). 73 The test is poorly standardized, and there is considerable interlaboratory variation between the titers regarded as positive Although indirect hemagglutination, ELISA, and AGID tests are available for serologic testing of antibody levels against the parasite, these tests are largely limited to specialized laboratories. Early IgM antibody responses appear by 1 month following infection and peak at 3 to 4 months, whereas IgG increases by 6 weeks and peaks by 3 months
Test results could be read more clearly by the indirect hemagglutination test especially in weakly positive cases. Ninety-six samples from suspected field cases collected from every region of Japan which were positive on the immunodiffusion test were also positive on indirect hemagglutination test. Serum samples from 420 horses in one race. Hemagglutination Principle - It is a type of agglutination test performed on RBCs. - many human viruses have the ability to bind to the surface structures on red blood cells from different species thereby causing agglutination Example - influenza virus binds to fowl's red blood cell Hemagglutination inhibition tests are simple, sensitive, inexpensive, and rapid and therefore are often the method of choice for assaying antibodies to influenza A virus. The test relies on the hemagglutination activity of the influenza HA and the ability of HA-specific antibodies to inhibit the virus from agglutinating erythrocytes (Fig. 13-5. Agglutination Test. Definitions. Agglutinin. Substance that induces particles (e.g. Bacteria, viruses, cells) to stick together, forming a clump or mass.

The particulate complement-fixing antigen coincided with the more dense peak but was distinguishable by its sedimentation in rate-zonal sucrose gradients. ESS was obtained from each of the complement-fixing-reactive gradient peaks by extraction with hot alkali and was quantified by a modified indirect hemagglutination test 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. Besides this, when considering the ELISA test as the reference test, the Indirect Hemagglutination Test had a co-positive reaction of 48.3% and a co-negative reaction of 86.5% in the Brazilian sera, and a co-positive reaction of 80.6% and a co-negative reaction of 61.3% in the Peruvian sera The indirect hemagglutination tests was negative, he underwent surgical resection through Suboccipital-retrosigmoid approach, intraoperative views showing two cystic masses with white cystic content, the cysts were broken and the cysts'membrane with scolex were removed smoothly which were not adherent to cerebellar parenchyma very much

The indirect hemagglutination assay (IHA) is the most frequently used serological test to confirm exposure to Burkholderia pseudomallei. Patients with culture-confirmed disease often have a nonreactive IHA at presentation and occasionally fail to seroconvert on serial testing. We investigated whether using antigens derived from the cultured isolates of persistently IHA-nonreactive patient sera. The indirect hemagglutination (IHA) test was used as a diagnostic method for infectious bovine rhinotracheitis:(IBR) virus infection in the field. Formalized sheep red blood cells were treated with tannic acid, sensitized with IBR virus, and used for the test as antigen.
