Serological Tests
Serological diagnosis of an acute infection can be done by the demonstration of seroconversion and/or agent-specific IgM antibodies in the serum samples. Seroconversion describes 4 fold or more increase in antibody levels of the serum samples which is collected at the acute and convelescent phase (10-15 days intervals) of an infection. As the detection of seroconversion is time-consuming, the a...
متن کاملSerological tests for syphilis.
Many of the nontreponemal or serological tests for syphilis involve the detection of serum antibodies (reagin) which are not directed against a component of the causative organism itself but may arise as a result of pathological changes brought about by proliferation of Treponema pallidum in host tissue. Test antigens for the detection of reagin are lipoidal, the main active component being the...

In a pilot study by field-screening in two different sauna baths, a day-sauna and a night-sauna, 318 homosexual men were investigated for syphilis and hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs).

متن کاملSerological tests for staphylococcal infection.
The need for a reliable serological test for occult staphylococcal infection has long been evident, especially for the diagnosis of lesions of the spine and hip. Earlier reports on the use of the anti-a-haemolysin (Lack and Shelswell, 1955; Lack, 1957), and anti-leucocidin tests (Towers and Gladstone, 1958; Towers, 1961) have placed us in a position to compare the value of these two tests; anti...
متن کاملSerological tests in 150 cases of leprosy.
Hansen's disease is considered to be one of the well-known infections which upset serological tests for syphilis in patients in whom there has been no past or current treponemal infection. The reason why lepers are biological false positive (B.F.P.) reactors and why this failure in the specificity of lipoidal reactions occurs remains obscure. The frequency of false positive reactions is said to...
