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

Abstract A rapid, semiquantitative hemagglutination inhibition assay for urinary luteinizing hormone (LH) and human chorionic gonadotropin is described. Midcycle LH peaks were detected in fresh, unprocessed urines from several individuals.

Erythropoietin assay by hemagglutination-inhibition.
The American journal of medical technology, 1975The immunochemical assay (HAI) for erythropoietin is accurate enough to detect small quantities and sensitive enough to demonstrate consistently and quantitatively the presence of erythropoietin in serum and urine. It will be the purpose of this report to describe in detail the procedure for the assay, the usefulness and value of erythropoietin testing

Assay of IgG and Other Human Plasma Proteins by Quantitative Inhibition of Passive Hemagglutination
The Journal of Immunology, 1972Abstract Using tanned human red cells coated optimally with isolated plasma proteins, specific agglutination in an AutoAnalyzer was quantitatively inhibited by solutions of the coating protein. IgG, IgM, IgA, IgD, IgE, transferrin, fibrinogen and ceruloplasmin were assayed in this manner.

AbstractA rapid passive hemagglutination assay (Rubaquick™) was developed that detects antibody to rubella virus in serum specimens. The test result is read visually after an incubation period of 15–30 minutes. When compared with a hemagglutination inhibition assay, the Rubaquick assay results obtained from 1,470 sera were greater than 99% specific ...

A digital data interpretation method for hemagglutination inhibition assay by using a plate reader
Analytical Biochemistry, 2019Hemagglutination inhibition (HAI) assay is a simple method quantifying relative binding activities of glycan-lectin interactions. Currently, interpretation of HAI data remains a manual task depending on visual observation. In this study we developed a digital data reading method for HAI assay by using the area scanning function of a microplate reader ...

Journal of Visualized Experiments
Accurate assessment of Newcastle disease virus (NDV) antibody titers is crucial for effective poultry disease control and surveillance. This article introduces an optimized method for preparing 4 hemagglutination units (4-HAU) antigen solution, a key component of the hemagglutination inhibition assay (HI) used in NDV serological detection.

Rubella immunity measured by hemagglutination inhibition and enzyme-linked immunosorbent assay.
Israel journal of medical sciences, 1985Evaluation of the immunity to rubella by the hemagglutination inhibition (HI) test and an enzyme-linked immunosorbent assay (ELISA), in a series of 1,697 sera collected from women of childbearing age, showed a 65% agreement; 33% were ELISA-positive and HI-negative at a 1:16 dilution and only 2% were ELISA-negative and HI-positive. Among 241 women given

Early pregnancy testing: a comparison of hemagglutination inhibition and radioreceptor assay.
The American journal of medical technology, 1982Two methods of early pregnancy testing, Neocept hemagglutination inhibition assay, and Biocept-G radioreceptor assay, were compared using 508 female patients from whom both urine and serum specimens were submitted for routine testing. A conventional urine HAI test was also used to support results.

An indirect enzyme-linked immunosorbent assay (ELISA) for the detection of antibody to a hemagglutinating duck adenovirus is described. Optimum conditions for the test were determined, and the system was compared with procedures currently used. Experimentally infected chickens were assayed for specific antibody by ELISA, hemagglutination inhibition (HI)
