Concerning the Wassermann Reaction

tionally collected and kept for some time, is a very poor control. Some positive sera give a complete fixation of the usual one or more MHD of the complement in a 1 in 200 dilution; others can do so in 1 in 5 dilution only. The margin.of variation allowed for in this control, 5 to 200, is too wide to be useful in indicating whether the antigen-antibody systems involved in the reaction of comple...

Serological Wassermann problem cases.

The subject of Wassermann "Problem" cases is of interest not only to the serologist but to the physician or clinician, upon whom devolves the responsibility for diagnosis. In the past there has been too little critical judgment by clinicians in assessing the results of the Wassermann reaction, and many practitioners may still regard a positive Wassermann reaction as in itself a diagnosis of syp...

Hence will you please publish the following in your valuable monthly :? False positive syphilitic reactions have been attributed to numerous causes, with sm...

Wassermann reactions simplified.

Most techniques at present in use for the Wassermann reaction require a great deal of bench and water bath space, are very time consuming, and put a considerable burden on those responsible for the preparation of glassware. The use of moulded perspex plates (M.R.C. pattern)* in this laboratory has cut down immensely the space and labour involved in doing routine Wassermann reactions, and has ad...
