Wassermann Test - Development and Refinement

Development and Refinement

The antibody test was developed by Wassermann, Julius Citron, and Albert Neisser at the Robert Koch Institute for Infectious Diseases in 1906. The test was a growth from the work of Bordet and Gengou on complementing-fixation reaction, published in 1901, and the positive reaction is sometimes called the Bordet-Gengou-Wassermann reaction or Bordet-Wassermann reaction.

The Wassermann test has been refined - the Kahn test, and the Kolmer test - and it is rarely used today. Replacement tests such as the VDRL test and the RPR test, initially based on flocculation techniques (Hinton), have been shown to produce far fewer false positive results. Indeed the "biologic false positives" of modern tests usually indicate a serious alternate condition, often an autoimmune disease.

Famous quotes containing the words development and/or refinement:

    If you complain of people being shot down in the streets, of the absence of communication or social responsibility, of the rise of everyday violence which people have become accustomed to, and the dehumanization of feelings, then the ultimate development on an organized social level is the concentration camp.... The concentration camp is the final expression of human separateness and its ultimate consequence. It is organized abandonment.
    Arthur Miller (b. 1915)

    Perhaps our own woods and fields,—in the best wooded towns, where we need not quarrel about the huckleberries,—with the primitive swamps scattered here and there in their midst, but not prevailing over them, are the perfection of parks and groves, gardens, arbors, paths, vistas, and landscapes. They are the natural consequence of what art and refinement we as a people have.... Or, I would rather say, such were our groves twenty years ago.
    Henry David Thoreau (1817–1862)
