A Simplified Hemagglutination Test for Farmer’s Lung

American Journal of Clinical Pathology, 1972
A simple method for the detection of hemagglutinating antibodies to the thermophilic actinomycetes is described. The antigens were derived from Micropolyspora faeni and Thermoactinomyces vulgaris . The key to the coupling of the antigen to the sheep erythrocytes is the use of chromium chloride.

Passive Hemagglutination Test (Boyden) [PDF]

, 1990
The etiological mechanism of anisakiasis involves an anaphylactic as well as an Arthus reaction in the digestive tract [1,2]. Cell-mediated immune reaction must also be considered in the establishment of an allergic condition in experimental anisakiasis [1].

An Immune Adherence Hemagglutination Test for Toxoplasmosis [PDF]

Archives of Ophthalmology, 1973
An immune adherence hemagglutination (IAHA) test has been developed for the rapid detection of antibodies againstToxoplasma gondii. This test, which utilizes human type 0 erythrocytes andToxoplasmaorganisms fixed in formaldehyde solution, is easy to perform, safe, and sensitive.

Passive Hemagglutination Test with Fowlpox Virus

Avian Diseases, 1970
SUMMARY A passive hemagglutination (HA) test using tanned horse red blood cells coated with partially purified fowlpox viral antigen, obtained by Genetron treatment, was used for titration of antibodies against fowlpox virus. HA antibodies were detected in sera of a few birds as early as 1 week after inoculation, though usually not until the third week

List of Plants Tested for Hemagglutinating Activity

Transfusion, 1961
Lists are given of all the plants tested in the authors' laboratory for hemagglutinating activity. The plants, arranged alphabetically by their scientific names, are grouped into three tables: (1) plants found to contain blood group specific lectins, (2) plants which gave negative or nonspecific extracts, and (3) plants which yielded hemolytic extracts.

Evaluation of the hemagglutination treponemal test for syphilis

Journal of Clinical Microbiology, 1984
The sensitivity and specificity of the hemagglutination treponemal test for syphilis (HATTS) was compared with the fluorescent treponemal antibody-absorption test (FTA-ABS) with 491 sera. Medical histories were obtained for 153 patients with seroreactivity in either treponemal test. Overall correlation with patient history was 96.7% for the FTA-ABS and

The Hemagglutination Test for Rheumatoid Arthritis

The Journal of Immunology, 1952
Summary The agglutinin titer of a mixture of sheep erythrocytes and the homologous agglutinin is significantly potentiated by the addition of certain animal sera including human. The magnitude of potentiation varies with different sera within species and is a function of dilution.

Rubella-Virus Hemagglutination-Inhibition Test

New England Journal of Medicine, 1967
THE isolation of rubella virus1 , 2 in 1961 opened a period of remarkable progress in studies of the virus,3 the disease4 and, recently, experimental vaccines for preventing the disease.5 , 6 Comparable progress has not been made in the development of simple, rapid serodiagnostic methods.

The indirect complement fixation hemagglutination and conglutinating complement absorption tests for viruses of the psittacosis-lymphogranuloma venereum group.

Journal of Immunology, 1951
Three new tests for demonstrating antibody against viruses of the psittacosis-lymphogranuloma venereum group are described. These are the indirect complement fixation test, which detects inhibitory antibody for these viruses in the sera of chickens ...

An Indirect Hemagglutination Test for Hydatid Disease

The Journal of Immunology, 1957
Summary By the employment of complement fixation and indirect hemagglutination tests 50 serum samples obtained from patients with hydatid disease and other conditions were tested. Of the 16 serum samples collected from hydatid disease patients positive results were obtained in 13 (81.25%) in indirect hemagglutination tests and in 11 (68 ...
