Hemagglutination Assay for Influenza Virus
Methods in molecular biology, 2014The hemagglutination assay (HA) is a tool used to screen cell culture isolates or amnioallantoic fluid harvested from embryonated chicken eggs for hemagglutinating agents, such as type A influenza. The HA assay is not an identification assay, as other agents also have hemagglutinating properties. Live and inactivated viruses are detected by the HA test.

Hemagglutination (Inhibition) Assay
Methods in molecular biology, 2014The hemagglutination assay is a simple and easy method to obtain semi-quantitative data on the sugar binding and specificity of a lectin. An active lectin agglutinates erythrocytes by recognizing a carbohydrate on the cell surface and forming a cross-linked network in suspension.

Hemagglutination Assay for the Avian Influenza Virus
Methods in molecular biology, 2008The hemagglutination (HA) assay is a tool used to screen cell culture or amnioallantoic fluid harvested from embryonating chicken eggs for hemagglutinating agents, such as type A influenza. The HA assay is not an identification assay, as other agents also have hemagglutinating properties.

Hemagglutination Assay for Antigen and Antibody Associated with Viral Hepatitis
Science, 1970Hemagglutination assays are described for measuring hepatitis-associated Australia antigen and antibody. Red cells coated with isolated antigen, with chromic chloride as a coupling agent, are used for detection of antibodies. Detection of the antigen in serums depends on inhibition of hemagglutination.

Diagnosis of Invasive Aspergillosis by Passive Hemagglutination Assay of Antibody
Journal of Infectious Diseases, 1980Sheep red cells treated with concanavalin A and sensitized with a partially purified aspergillus antigen were used to detect antibody to Aspergillus by passive hemagglutination (PHA). Sera from eight patients with aspergillomas or allergic aspergillosis had PHA titers of greater than or equal to 1:800 and antibody detectable by immunodiffusion (ID). Of

Passive Hemagglutination Assay for Antibody to Subtypes of Hepatitis B Antigen
The Journal of Immunology, 1974Abstract Antibody to the d and y subtypes of hepatitis B antigen (HB Ag) was detected by a modification of the passive hemagglutination assay (PHA) for anti-HB Ag. With this technique, anti-d or anti-y activity could be detected in many sera negative for anti-HB Ag by counterelectrophoresis but positive by PHA.

Development of Hemagglutination Assays
Vox Sanguinis, 1977Abstract. Studies were undertaken to enhance the sensitivity of a previously developed RPHA test for HBsAg. A net increase in sensitivity of approximately 3‐fold was achieved by modifying the elution procedure used to purify chimpanzee anti‐HBs by affinity chromato‐graphy.

Hemagglutination assay for human serum fibronectin
Journal of Immunological Methods, 1985A hemagglutination assay for human serum fibronectin (Fn) is described. The assay is based on the capacity of Fn to bind to gelatin. Purified and human serum Fn agglutinate chromic chloride treated sheep red cells coated with gelatin in a quantitative and reproducible manner.

Hemagglutination inhibition assays
Seminars in Avian and Exotic Pet Medicine, 2002Hemagglutination is a useful characteristic of many viruses because it can provide a simple and efficient method of detecting antihemagglutinating activity in serum from exposed animals. This is called hemagglutination inhibition (HI), and HI assays are used extensively to detect and titrate antibodies to many avian diseases including Newcastle disease

Passive Hemagglutination Assays for the Detection of Antibodies to Herpes Viruses
Microbiology and Immunology, 1993AbstractA simple and effective method for the detection of antibodies to herpes simplex virus (HSV), human cytomegalovirus (HCMV) and varicella‐zoster virus (VZV), has been established using the passive hemagglutination assay (PHA) in combination with viral specific glycoproteins.
