Comparison of haemagglutination-inhibition and single radial haemolysis techniques for detecting antibodies to influenza A and B viruses

Quantitation and analysis of the specificity of post-immunization antibodies to influenza B viruses using single radial haemolysis.

The single radial haemolysis (SRH) technique detected anti-B/HK/8/73 HA antibody rises in 59-85% of paired sera from persons immunized with different influenza vaccines. In contrast, analysis of the same sera by the haemagglutination inhibition (HI) test indicated significant antibody rises in only 27-54% of paired sera. High levels of antibody were detected to influenza B/HK/8/73 and B/Singapo...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Comparison of passive haemagglutination and haemagglutination-inhibition techniques for detection of antibodies to rubella virus.

Because of the technical problems and length of time involved in the satisfactory performance of the haemagglutination-inhibition test for detection of rubella-specific antibodies, a commercially available passive haemagglutination (PHA) kit utilising rubella antigen-sensitised human erythrocytes was tested for its suitability for use in diagnostic laboratories. The immune response to acute rub...

Comparison of radial haemolysis with haemagglutination inhibition in estimating rubella antibody.

Radial haemolysis (RH) for assaying rubella antibody was studied in parallel tests with haemagglutination-inhibition (HAI) on 1102 sera from adult women. Simple to perform and economical in reagents, the RH test is as sensitive as the HAI test and is a useful method of screening antenatal and other sera for rubella immunity. It detects IgG but not IgM antibody.
