Cryopreserved erythrocytes in clinical laboratory hemagglutination and hemagglutination inhibition tests

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.

Comparison of Mycoplasma synoviae Hemagglutinating Antigens by the Hemagglutination-Inhibition Test

Avian Diseases, 1980
Mycoplasma 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 ...

Influence of albumin on rubella virus hemagglutination and the hemagglutination-inhibition test

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 in Tularemia

The Journal of Immunology, 1959
Summary 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 ...

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 for enteric fever

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

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

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

A New Hemagglutination Test for Rheumatoid Factors

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

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 ...
