Hemagglutination Assay for Antigen and Antibody Associated with Viral Hepatitis

Science, 1970
Hemagglutination 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, 1980
Sheep 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

Erythropoietin assay by hemagglutination-inhibition.

The American journal of medical technology, 1975
The 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

Potato lectin activity assay based on hemagglutination

Journal of the Science of Food and Agriculture, 1992
AbstractA quantitative method for the determination of potato lectin activity has been developed. In the method, lectin is incubated with an excess of red blood cells (RBC) in phosphate buffered saline at 25 °C. Maximum agglutination is reached within 60 min. Agglutinated RBC are then separated from nonagglutinated RBC by filtration.

Hemagglutination Assay For Determination Of Human Factor VIII:C

Thrombosis and Haemostasis, 1981
New methods for the determination of human factor VIII clotting protein (F. VIII:C) have been developed utilizing hemagglutination technique without using any other coagulation proteins in the assay. A 50% ammonium sulphate precipitate of the plasma from a hemophilic patient containing high titer of F.

Reactivity of nonsensitized control erythrocytes in rubella passive hemagglutination assays

Journal of Clinical Microbiology, 1983
Two commercially available, nonsensitized control erythrocytes for use in rubella antibody passive hemagglutination assays detected nonspecific reactions in 10 of 600 (1.7%) and 9 of 500 (1.8%) sera tested. Reactive sera were positive with one or the other cell type, but not both.

Passive Hemagglutination Assay for Antibody to Subtypes of Hepatitis B Antigen

The Journal of Immunology, 1974
Abstract 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.
