    August von Wassermann, (born Feb. 21, , Bamberg, Bavaria [Germany]—died Ma , Berlin, Ger.), German bacteriologist whose discovery of a universal blood-serum test for syphilis helped extend the basic tenets of immunology to diagnosis.. “The Wassermann reaction,” in combination with other diagnostic procedures, is still employed as a reliable indicator for the disease. gives a positive Wassermann reaction, and it is assumed in this case that such a reaction does not mean syphilis. It is, however, interesting that Byrom Bramwcll,3 in a book published before the Wassermann test camo into vogue, gives syphilis as one of the causes of infective endocarditis ; so acute an observer must have had good reason for his.

In a numerical (or otherwise) model, the Sensitivity Analysis (SA) is a method that measures how the impact of uncertainties of one or more input variables can lead to uncertainties on the output variables. This analysis is useful because it improves the prediction of the model, or. Wassermann test definition: a diagnostic test for syphilis | Meaning, pronunciation, translations and examples.

Wyler, in this pamphlet, presents a method for raising the sensitiveness of the Wassermann method number 1, Medical Research Council, an improved technic of which he described inby increasing the quantity of serum used in the test.

This method was included in the League of Nations' serologic conferences of Copenhagen () and of Montevideo () and was considerably less sensitive than the Kahn test. Miscellaneous: A Method of Increasing the Sensitiveness of the Wassermann Test. No pp pp.

ref Abstract: The method described in this report is identical with No. 1 Method M.R.C. as modified by Wyler (M.R.C. Special Report Series No.

) with the exception that the quantity of tested serum is greater, the amounts being two, three, four and five times respectively, that used in Author: E. Wyler. CONCLUSION The sensitiveness of the Wassermann reaction has been increased by using a serum dilution of 1/2 as compared with 1/5.

There appeared to be no reduction in the specificity of the test Cited by: 6. Increased Sensitiveness of the Wassermann Test by the Use of Specific Antigen (Pallida Reaction of Gaehtgens). The author has tested out on 1, sera the Gaehtgens method of the Wassermann test [this Bulletin,v.

They propose a method in which a serum containing some specific reagin but insufficient to give a positive reaction can be made to show its luetic character by the addition of reagin of a known positive serum Author: H.

In the second article the authors give the results of 1, tests in parallel with the ordinary Wassermann and with Kahn, Müller and Meinicke Klärungs-Reaction.

The results are shown in the above table constructed from the original. From these the authors conclude that the theoretical basis of the test is substantiated by the results in that the method does increase the sensitiveness of the.

THE Kahn test is a flocculatIOn test used in the serum diagnosis of syphilis. In December,this test was adopted by the United States Navy as the official sero-diagnostic method in syphilis in place of the Wassermann reaction. Winder and Michael () have reported.

The Results and Interpretation of the Wassermann Test American J. Sc., Phila. 41 5 Medical Research Committee Special Report Series. The Wassermann test or Wassermann reaction (WR) is an antibody test for syphilis, named after the bacteriologist August Paul von Wassermann, based on complement was the first blood test for syphilis and the first in the nontreponemal test (NTT) category.

Newer NTTs, such as the RPR and VDRL tests, have mostly replaced it. The amount of it used in the Bordet-Wassermann test is cc. and that for the tuberculosis complement fixation reaction is cc. In Bordet-Wassermann tests sera, using the Bordet-Ruelens antigen, the removal of the globulins by the method described resulted in an important increase in the sensitiveness, as shown in the following table.

Sensitivity can be increased by examining multiple fecal specimens, by using concentration techniques, and by plating feces on an agar plate and inspecting for tracks of colonies created by bacteria being dragged by migrating larvae.

Incubating stool mixed with bone charcoal can also enhance recovery (the Harada-Mori culture technique). Wassermann Test (medicine), a method of diagnosing syphilis by means of a serological reaction.

Named after A. von Wassermann. The Wassermann test is based on the ability of blood serum of syphilitic patients to form a complex with the appropriate antigen that absorbs complement (a component of normal serum); erythrocytes of sheep’s blood serve as the.

The vast majority of patients with syphilis were positive in the Wassermann test, whereas serum samples from most other patients were negative. The test was soon adopted by leading medical centers throughout. test and the fewer its reagents, the less liable is it to be affected by conditions of climate and temperature.

The ideal test, therefore, would require to combine a minimum of complexity with a maximum of accuracy. At the time the number of tests claiming to equal the Wassermann reaction in value was large and steadily increasing.

The original Wassermann test has undergone many changes until, at present, the technic and methods bear little resemblance, except in prin-ciple, to the early test. Most of the studies have been made, and modi-fications proposed, with a view to increasing uniformity of results.
