Evaluation of the gonococcal complement-fixation test.

Evaluation of the gonococcal complement-fixation test.

The gonococcal complement-fixation test (GCFT), based on the same principle as the Wassermann reaction (WR), has been in use for over 60 years. The test was applied for the first time, using a culture of the gonococcus as antigen, by Muller and Oppenheim (1906) to establish the diagnosis in a case of arthritis. Teague and Torrey (1907) suggested that negative results in the GCFT were due to dif...

Gonococcal Complement-fixation Test in Complicated and Uncomplicated Gonorrhoea.

The complement-fixation reaction with gonococcal antigen (gonococcal complement-fixation test: GCFI) is based on the same serological principle, and has been known for about as long, as the Wassermann reaction. Up to the 1940's the GCFT was widely employed, but as improvements in cultivation techniques for gonococci were developed, interest in the complement-fixation reaction diminished. At pre...

Detection of rotavirus by Latex Agglutination Test (Rotales); Comparison with Electron Microscopy and Complement Fixation Test

Quantitative micro-complement fixation test.

A quantitative micro-complement fixation test capable of detecting nanogram quantities of antigen is described. The test is simple to perform and is highly reproducible. Typical results from three antigen-antibody systems are given.

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
