Cryopreserved erythrocytes in clinical laboratory hemagglutination and hemagglutination inhibition tests [PDF]
Journal of Clinical Microbiology, 1985 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.

Influence of albumin on rubella virus hemagglutination and the hemagglutination-inhibition test [PDF]
Canadian Journal of Microbiology, 1975 The 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.

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 ...

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 ...

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.

Modification of meningococcal polysaccharide antigens for use in passive hemagglutination tests.
Journal of Immunology, 1968Lipopolysaccharide antigens derived from the cell walls of several Gram-negative bacteria by any of the commonly employed procedures have little erythrocyte-sensitizing activity.

An evaluation of the hemagglutination test for tuberculosis
The American Journal of Medicine, 1951Abstract 1.1. A clinical evaluation was made of the Scott and Smith modification of the hemagglutination test for tuberculosis in normal individuals and in subjects with tuberculosis, sarcoidosis, following BCG vaccination and with miscellaneous diseases. Tests were performed on sera obtained from over 400 patients. 2.2.

A New Hemagglutination Test for Rheumatoid Factors [PDF]
American Journal of Clinical Pathology, 1970 A new commercially available reagent for testing for rheumatoid factors was evaluated in patients with rheumatoid arthritis and in controls. It provided less sensitivity than the bentonite flocculation and latex fixation tests, which depend on the use of human immunoglobulin G, but provided excellent correlation with results obtained in the Waaler-Rose

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 ...

Passive hemagglutination test for enteric fever [PDF]
Journal of Clinical Microbiology, 1987 A 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
