  August Paul von Wassermann (www.whonamedit.com)
Wassermann in 1898 became titular professor and in 1901 he was habilitated as Privatdozent in internal medicine at the Friedrich Wilhelm University in Berlin.
Wassermann left the institution in 1913 to become director of the department of experimental therapy at the Kaiser-Wilhelm-Gesellschaft for the Advancement of Science in Berlin Berlin-Dahlem.
Wassermann early understood the importance of the young science of bacteriology, and made the acquaintance of Paul Ehrlich (1854-1915) of whom he became a pupil and colleague.

  Wassermann test - Wikipedia, the free encyclopedia
Syphilis-specific antibodies (reagines) react with the lipid - the Wassermann reaction of antiphospholipid antibodies (APAs).
The antibody test was developed by Wassermann 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.

 Blood test - Wikipedia, the free encyclopedia
Blood tests are laboratory tests done on blood to gain an appreciation of disease states and the function of organs.
While the regular glucose test is taken at a certain point in time, the glucose tolerance test involves repeated testing to determine the rate at which glucose is processed by the body.
DNA testing is today possible with even very small quantities of blood: this is commonly used in forensic science, but is now also part of the diagnostic process of many disorders.

 Syphilis Test | World of Invention
Wassermann was influenced by the work of German researcher Paul Ehrlich (1854-1915), who established basic theories of blood immunity.
Wassermann's test consisted of taking a blood sample from the patient, and testing it for the antibody to the syphilis bacterium.
The Wassermann test was useful in diagnosing syphilis in 95% of cases.

August Paul von Wassermann (21 February 1866 - 16 March 1925) was the German bacteriologist.
He developed a complement fixation test for the diagnosis of syphilis in 1906, just one year after the causative organism had been identified.
The Wassermann test remains a staple of syphilis detection and prevention in some areas, although it has often been replaced by more modern alternatives.

 TIME Magazine Archive Article -- A New " Wasserman Test " -- Mar. 31, 1923   (Site not responding. Last check: 2007-10-08)
August von Wassermann, distinguished German serologist, who developed the so-called"; Wassermann test "for syphilis, announced another achievement in preventive medicine— a method of determining the presence in the body of latent tuberculosis before it becomes active in the lungs.
Wassermann's method—he refuses to call it a discovery—is the result of long research based on the groundwork of American and French investigators, during which he tried out more than 500 different serums.
While he does not claim that his test will make possible 100% accuracy in diagnosis and complete cure of the disease, Dr. Wassermann believes that it will enable the forces which are already fighting tuberculosis with well-understood methods to get a stranglehold on it in its earliest stages and greatly reduce the present death rate.

A negative test, however, by no means excludes a syphilitic infection, as is frequently shown in the case of typical gummas of the skin.
The test, let me add, is frequently alternately positive and negative in the same individual; is, also, often negative when the blood test is employed and positive when a spinal test is made, or vice versa.
They know their tests are inaccurate and they can't tell when they are right or wrong (if they could they would not need the tests), but they know to the smallest fraction of one percent, just how often their tests are wrong.

The tests put the emphasis in education not on what is important but on what is diminishing for students' learning and their overall growth.

 Wassermann's reaction (www.whonamedit.com)
Several negative Wassermann reactions a few years after treatment indicate the absence of syphilis.
Wassermann described his test one year after Fritz Richard Schaudinn (1871-1906) and Paul Erich Hoffmann's (1868-1959) discovered the causative organism of syphilis.
Many modifications have since been made of this test, such as the Kahn, Kolmer, etc, but the general principled applied by Wassermann continue to guide the procedures.

 Archives of Pathology & Laboratory Medicine: Antiphospholipid antibodies
Antiphospholipid antibodies (APAs) were first described by Wassermann et al in 1906.1 The Wassermann test was a complement fixation procedure using saline extracts from the liver of fetuses with congenital syphilis.
Following the introduction of the Wassermann test, a variety of procedures using antigens derived from alcoholic extracts of normal tissue were described.
False-positive tests using the VDRL were classified as either acute or chronic biologic false positives (BFPs).3 The chronic BFP was defined as a positive nontreponemal-- based screening test that persisted for 6 months or longer.

 [P&S Medical Review:Apr:95] H. Houston Merritt and Neurosyphilis, Then and Now
Merritt relied heavily on the CSF Wassermann test, which was regarded as highly specific because false positive reactions were restricted to people with leprosy, frambesia and trypanosomiasis, none of which were commonly encountered in Boston.
This rabbit infectivity test (RIT) was available then but it was mentione d only in passing in his monograph, probably because it was cumbersome, time-consuming and expensive, factors that precluded its general application to populations.
The blood Wassermann was neg ative in 26 of the 80 patients (36%) and was not recorded in six others.

 Syphilis: Chapter XIV
For the sake of those who may still have faith in the Wassermann test, let me say that in a few of these cases this test was made (in one case 9 tests in two years), subsequent to the disappearance of symptoms, and the tests proved negative in each case.
Nine negative tests in two years, without a single positive test should satisfy the most ardent supporter of the test and the prevailing views of the disease.
He said: "I have had three Wassermann tests made and they are all negative, but I am treating him for syphilis, anyway." He had been taught, in medical school, that this disease is due to "syphilis" and he had blindly accepted the words of his professors and text-book writers.

On that occasion, the only test administered to him was a Wassermann reaction test, which proved negative: there was no visual inspection or any other kind of examination.
Only in the middle of January 1948 did a different doctor cause blood tests to be made on A. In both cases the Wassermann test proved to be extremely positive, a fact which A communicated to Dr J on 14 February.
The Court of Appeal also held that in failing to follow the prescribed tests and other safety measures, Dr J was at fault and that this fault was a cause of the plaintiff’s being infected with syphilis.
