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.

2021年3月18日 · Hemagglutination is a reaction that causes clumping of red blood cells in presence of some enveloped viruses, such as the influenza virus. A glycoprotein on the viral surface,...

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 · Hemagglutination. Agglutination of red blood cells is called hemagglutination. 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.

Hemagglutination is a classical method for viral diagnosis, but is still used for diagnosis of influenza virus today. One outstanding advantage of this method is that it does not require any equipment. Moreover, it is a robust and rapid diagnostic tool, …

2024年10月7日 · Hemagglutination serves as a foundational technique in blood typing, a crucial process for ensuring compatibility in blood transfusions. By utilizing specific antibodies that target antigens on the surface of red blood cells, this method determines an individual’s blood group.

4.1.1.3.1 Hemagglutination. Immune hemagglutination, used for cross-matching donor red blood cells (RBCs), refers to coagulation of RBCs, with antibodies either directed to the RBC themselves or specific carbohydrates coating the cells (Gyenes & Sehon, 1962). The method is highly sensitive, and the degree of agglutination is directly ...

2023年10月12日 · In 1941-1942, an American virologist named George Hirst developed the hemagglutination assay (HA) and the hemagglutination inhibition test (HI or HAI), procedures for detecting the relative concentration of viruses, bacteria, or antibodies.
