Hemagglutination Test for Toxoplasmosis
Science, 1957The importance of adequate serological tests for toxoplasmosis is accentuated by the tremendous gains in knowledge concerning this infection, which stemmed from the description of the in vitro dye test by Sabin and Feldman in 1948. In the less than 8 years since this discovery, the serology of toxoplasmosis has been characterized and forms of the ...

Hemagglutination Tests for Syphilis Antibody
American Journal of Clinical Pathology, 1978In a study of serodiagnosis of syphilis, the authors compared the specificities and sensitivities of two hemagglutination tests, a sheep-erythrocyte test (MHA-TP) and a trukey-erythrocyte test (TPHA), with those of the Fluorescent Treponemal Antibody-Absorption (FTA-ABS) test.

A hemagglutination test for cryptococcosis
The American Journal of Medicine, 1962Abstract Details are presented of a new test, the cryptococcal hemagglutination test, which appears to offer promise not only as a diagnostic aid in human cryptococcosis but also as a laboratory correlate of the clinical course. The sensitivity of the cryptococcal hemagglutination test was compared with that of agglutination and precipitin tests ...

Rubella-Virus Hemagglutination-Inhibition Test
New England Journal of Medicine, 1967THE 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.

Various concentrations of pig, guinea pig, chicken, and turkey erythrocytes (RBCs) were cryopreserved and compared with fresh RBCs in hemagglutination and hemagglutination inhibition tests. Hemagglutination and hemagglutination inhibition titers obtained with cryopreserved or fresh RBCs from the same donor differed by not more than one twofold dilution.

Passive Hemagglutination Test with Fowlpox Virus
Avian Diseases, 1970SUMMARY 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

Passive hemagglutination test for enteric fever
Journal of Clinical Microbiology, 1987A passive hemagglutination (PHA) test for serodiagnosis of enteric fever was developed by sensitizing glutaraldehyde-preserved erythrocytes with lipopolysaccharide from Salmonella serogroups A, B, C, and D singly or simultaneously. The lipopolysaccharide-sensitized erythrocytes were tested with sera from 200 blood donors, 100 patients whose hemoculture

Comparison of Mycoplasma synoviae Hemagglutinating Antigens by the Hemagglutination-Inhibition Test
Avian Diseases, 1980Mycoplasma synoviae (MS) strains were isolated from the trachea of hens from MS-positive broiler breeder flocks having progeny condemnations due to airsacculitis. Hemagglutinating (HA) antigens were made from several strains. The HA antigen made from the 95th medium passage of MS FMT strain was compared with that of the standard MS WVU 1853 strain by ...
