Passive Hemagglutination Test (Boyden)
1990The 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].

Hepatitis A virus hemagglutination and a test for hemagglutination inhibition antibodies
Journal of Clinical Microbiology, 1989Like enteroviruses, hepatitis A virus (HAV) hemagglutinated various species of erythrocytes under similar conditions. HAV-specific antibodies in both acute- and convalescent-phase sera were found to inhibit hemagglutination. The HAV hemagglutination inhibition test can be used for diagnosis, epidemiological surveillance, and vaccine assessment.

Hemagglutination Tests with Ascaris Antigens
The Journal of Immunology, 1958Summary Antisera against Ascaris lumbricoides var suum, Ascaris lumbricoides, Toxocara canis, and Toxocara cati were prepared in rabbits by injection of lyophilized antigen and infection with viable eggs. These antisera cross-reacted with Ascaris and Toxocara antigens in hemagglutination tests.

Hemagglutination Test in Tularemia
The Journal of Immunology, 1959Summary Agglutinin and hemagglutinin titers were determined in 59 cases of laboratory-acquired tularemia occurring in 56 cases of laboraotry-acquired tularemia occurring in 56 vaccinated persons. A 4-fold rise in agglutinins was observed, on the average, on the 19th day of illness and the mean peak titer of 1:1280 sometime during the ...

Influence of albumin on rubella virus hemagglutination and the hemagglutination-inhibition test
Canadian Journal of Microbiology, 1975The HEPES–saline–albumin–gelatin (HSAG) diluent found optimal for agglutination of fowl erythrocytes by rubella virus antigen is also optimal for agglutination of trypsin-treated human group O cells. Albumins from different commercial sources, however, can have varying inhibitory effects on rubella hemagglutination titers.

Toxoplasma Hemagglutination Test
Archives of Ophthalmology, 1961A new interest concerning the importance of Toxoplasma as an etiological agent in granulomatous uveitis followed the microscopic discovery of Toxoplasma organisms in eyes removed from 41 patients by Wilder in 1952.1The diagnostic methods which were subsequently developed for the detection of Toxoplasma antibodies include the complement-fixation test by

A Simplified Hemagglutination Test for Farmer’s Lung
American Journal of Clinical Pathology, 1972A 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.

Treponema pallidum Hemagglutination (TPHA) Test
2018Syphilis is a sexually transmitted disease caused by bacteria called Treponema pallidum, and range from asymptomatic to severe. Patients with suspected syphilis should undergo a non-treponemal screening test (rapid plasma reagin) and positive results must be confirmed with a test specific to T. pallidum antigen. Here, the treponemal test, T.
