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.

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.

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.

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 ...

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
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.

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.

A New Hemagglutination Test for Rheumatoid Factors
American Journal of Clinical Pathology, 1970A 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

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 ...
