The indirect hemagglutination test for the detection of antibodies in cattle naturally infected with mycoplasmas. Abstract The indirect haemagglutination (IHA) test was performed on 200 mastitic cows (naturally infected with mycoplasmas), using glutaraldehyde treated sheep erythrocytes sensitized either with M. agalactiae subsp. bovis or M ...

Hemagglutination Inhibition Certain viruses have a protein on their surface that in-teracts with red blood cells and is able to attach to them. This property is called hemagglutination and the surface protein of the virus is hemagglutinin. The inhibition or blocking of this activity is the basis of the hemagglutination inhibition (HI) test. The ... Therefore, treponemal-specific tests like enzyme immunoassay (EIA), T. pallidum hemagglutination assay (TPHA), microhemagglutination, fluorescent treponemal antibody absorption test (FTA-abs), and the enzyme-linked immunosorbent assay (ELISA) that detect IgG antibodies to antigenic components of T. pallidum are used primarily to confirm the ... w hich of the following tests is most effective in determining whether someone has been infected with the H1N1 influenza virus? A) a viral neutralization test. B) an immunodiffusion test. C) a viral hemagglutination test. D) an antibody titer test. E) a western blot

Which of the following tests is most effective in determining whether someone has been infected with the H1N1 influenza virus? a. an antibody titer test b. an immunoblot c. an immunodiffusion test d. a viral hemagglutination test e. a viral neutralization test The study was proposed to see the usefulness and correlation of Treponema pallidum hemagglutination assay (TPHA) with varying titers of Venereal Disease Research Laboratory (VDRL) test. Materials and Methods: Over a period of 2 years, 22,351 sera were subjected to screening for syphilis by VDRL test. 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).
