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.

2022年12月13日 · Hemagglutination assay (HA) is a type of immunoassay in which erythrocytes are used as carrier particles and are commonly preferred for serological diagnosis of various infections.

2024年4月21日 · One common assay that uses hemagglutination is the direct Coombs’ test, also called the direct antihuman globulin test (DAT), which generally looks for nonagglutinating antibodies. The test can also detect complement attached to red blood cells.

2024年10月7日 · Explore the principles and applications of hemagglutination assays in virology and blood typing, enhancing your understanding of these essential techniques. Hemagglutination assays are pivotal in various biological and medical fields, facilitating the study of viruses, bacteria, and blood typing.

2023年10月12日 · The hemagglutination Assay is a useful tool for determining the presence or absence of hemagglutinin in allantoic fluid derived from embryonated eggs. While it is a more time-consuming approach than the Rapid Diagnosis Test (RDT), it has its own set of advantages and applications.

2021年3月18日 · Hemagglutination inhibition assay (HIA) is used to detect and titrate antibodies developed against a virus. In HIA, an absence of hemagglutination is observed to detect the presence of...

2024年10月7日 · Hemagglutination assays have emerged as a fundamental technique due to their simplicity, cost-effectiveness, and wide applicability. By understanding how these assays work, researchers can unlock critical insights into viral behavior and infection mechanisms.

2024年5月17日 · The hemagglutination assay, also known as the haemagglutination assay (HA), and the hemagglutination inhibition assay (HI or HAI), were developed by George Hirst, an American virologist, in the early 1940s. These assays serve as valuable methods for quantifying the relative concentration of viruses, bacteria, or antibodies.

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.

Hemagglutination, or haemagglutination, is a specific form of agglutination that involves red blood cells (RBCs). It has two common uses in the laboratory: blood typing and the quantification of virus dilutions in a haemagglutination assay.
