HA and HAI apply the process of hemagglutination, in which sialic acid receptors on the surface of red blood cells (RBCs) bind to the hemagglutinin glycoprotein found on the surface of influenza virus (and several other viruses) and create a network, or lattice structure, of interconnected RBCs and virus particles. [2] .

Hemagglutination inhibition test is widely used for the diagnosis of infection caused by orthomyxoviruses (influenza), paramyxoviruses (measles, mumps), mononucleosis, arboviruses-togaviruses (including rubella), flaviviruses, and bunyaviruses.

To evaluate the efficiency of recombinant calcium binding domain containing protein by Indirect Haemagglutination Assay (IHA) against a commercial ELISA among amoebic liver abscess cases and control group.

In this study we have confirmed the utility of IHA as an initial screening test for the investigation of hospitalized patients clinically suspected of having acute leptospirosis. We did not titrate sera which reacted in the IHA, although this is recommended by the manufacturer.

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. Both false negatives and ...

An indirect hemagglutination test (IHA) and a coagglutination test (CA) were evaluated using saline, boiled, and autoclaved extracts for serotyping Haemophilus parasuis. CA showed several cross-reactions, whereas IHA gave rise to specific reactions, ...

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. It has been used extensively during ...

2008年12月1日 · 间接红细胞凝集试验（indirect haemagglutination test，IHA）是以红细胞为载体，将血吸虫可溶性虫卵抗原（SEA），吸附到经醛化和鞣酸处理的红细胞（人O型或绵羊红细胞）表面，吸附有抗原的红细

Among 72 patients clinically suspected of Entamoeba histolytica (E. histolytica) infections, 39 positive cases (54%) were detected serologically by the indirect hemagglutination (IHA) test. Parasitologically, microscopic examination of three consecutive stool specimens from all these patients indica …

1.An indirect hemagglutination assay (IHA) consisting of glutaraldehyde-fixed sheep red blood cells (SRBC) coated with the supernatant of sonicated HPS serovar 4 and 5 cells was established.将副猪嗜血杆菌 (Haemophilus parasuis,HPS)血清型4、5型分离菌株经超声波破碎处理后的产物致敏醛化红细胞,建立了检测HPS抗体的间接血凝试验方法。
