Studies on Hemagglutination and Hemolytic Test

A hemolytic modification of the hemagglutination test for antibodies against tubercle bacillus antigens.

A specific hemagglutination reaction has been described (1) between the sera of tuberculous experimental animals or human beings and sheep erythrocytes treated with extracts or products of the culture filtrates of tubercle bacilli. Observations on this reaction have been confirmed and extended by other investigators (2-6). The present paper is concerned with a modification of this test which in...

Studies on hemagglutination activity of caprine herpesvirus-1

The aim of this study was to investigate the hemagglutination properties of caprine herpesvirus-1(CpHV-1) and their application for CpHV-1 antigen detection and evaluation of the dynamics of postinfectious/vaccine antibody production. CpHV-1 hemagglutination activity was proved only with mouseerythrocytes, PBS and saline solutions at 4°C and 22°C. In vaccinated animals, goats and bucks withresp...

Cold hemagglutination in acute and chronic hemolytic syndromes.

the relationship between eq, iq and test format: a study on test fairness

the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...

Hemagglutination treponemal test for syphilis.

Sera from 290 hospital patients were tested to compare the sensitivity, specificity, and reproducibility of the hemagglutination treponemal test for syphilis (HATTS) with the fluorescent treponemal antibody absorption test (FTA-ABS). Complete agreement was obtained between the methods when 142 syphilitic sera from patients with various stages of syphilis were tested. By using clinical histories...
