A screen test for rubella haemagglutination inhibition antibodies.
The findings agree closely with those of Hobbs and Aw (1968). The isoamylase patterns of normal plasma and urine are similar, though the activity in urine is greater. Three bands are usually found in normal urine, the slower, and usually more distinct, band being the pancreatic component, and the faster those derived from salivary gland. The activities of these isoenzymes in plasma appear to be...
متن کاملSimplified method for the rubella haemagglutination inhibition screening test.
A modification of the rubella haemagglutination inhibition (HAI) test in which both pretreatment and serum titration are carried out in wells of the same microtitre plate saves time, labour, and materials and gives results comparable to a conventional HAI procedure.
متن کاملA haemagglutination and haemagglutination inhibition test for bluetongue virus.
Haemagglutination of bluetongue virus (BTV) was demonstrated for the first time by making use of a purified preparation of the virus. The reaction was found to be independent of variations in the pH, temperature, buffer system and origin of the erythrocytes used in the test. A haemagglutination inhibition test, subsequently developed, was demonstrated to be serotype specific. The storage of the...
متن کاملDetection of rubella haemagglutination-inhibition (HAI) and virus-specific IgM antibody using trypsin-treated human group O erythrocytes in the HAI test.
The modification of the standard rubella haemagglutination-inhibition (HAI) test using trypsin-treated human group O erythrocytes instead of chick erythrocytes was evaluated. In a comparative study we found that, of 816 samples tested by both methods, the titres of 807 (98.9%) sera were in close agreement within an acceptable twofold difference. Trypsin-treated human group O erythrocytes usuall...
متن کاملRapid latex agglutination test for rubella antibody.
The latex agglutination card test (Rubascan) for the detection of rubella antibody was compared with the standard hemagglutination inhibition and enzyme-linked immunosorbent assay tests. There was complete agreement with sera which had hemagglutination inhibition titers of >/=16. Sera with low levels of antibody which were positive in the enzyme-linked immunosorbent assay, however, gave negativ...
