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

Clinica Chimica Acta, 1977
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.

Avian Diseases, 1983
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)

The Journal of Immunology, 1962
Summary The CF, HI and neutralization tests have been used to assay the antibody content of sera from animals and man following vaccination with killed measles virus and/or natural infection with the live virus. The CF test was demonstrated to be the least sensitive method of assay.

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.

OPTIMIZATION OF THE HEMAGGLUTINATION INHIBITION ASSAY FOR H5 AVIAN INFLUENZA STRAINS
2015Antibodies generated in response to influenza vaccine or virus exposure can be detected by the Hemagglutination Inhibition Assay (HAT). Avian influenza strains are more difficult to test than seasonal strains. Previous improvements to the assay include use of horse blood instead of turkey blood.

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

Laboratory animal science, 1989
The sensitivity of a newly developed enzyme-linked immunosorbent assay (ELISA) for detection of antibody to K virus was compared with the sensitivities of an immunofluorescence assay (IFA) and a hemagglutination inhibition assay (HIA). Specific pathogen-free BALB/c RIVM mice, 5 weeks old, were inoculated intraperitoneally with a mouse organ suspension ...
