Laboratory diagnosis of syphilis with automated immunoassays

Laboratory diagnosis of syphilis with automated immunoassays.

The serological detection of specific antibodies to Treponema pallidum is of particular importance in the diagnosis of syphilis. The purpose of this study was to evaluate diagnostic performances of automated immunoassays in comparison with T. pallidum hemagglutination test (TPHA) and Western Blot (WB). The retrospective study was performed with different panels of sera: 244 clinical and serolog...

The laboratory diagnosis of syphilis.

Syphilis has several clinical manifestations, making laboratory testing a very important aspect of diagnosis. In North America, many unsuspected cases are discovered by laboratory testing. The etiological agent, Treponema pallidum, cannot be cultured, and there is no single optimal alternative test. Serological testing is the most frequently used approach in the laboratory diagnosis of syphilis...

Performance characteristics of three automated immunoassays for thyroid hormones

Background: Since the introduction of the first radioimmunoassay, several improvements have been made in the design of immunoassays such as method of antibody production, labeling, automation and detection technology. We performed an analytical evaluation of the new electrochemiluminescent immunoassay (ECLIA) for serum TSH, FT4 and T3 in the Elecsys 2010 immunoassay system and compared the resu...

The laboratory diagnosis of gonorrhoea and syphilis infection.

Following a decline in prevalence during the 1980s and early 1990s, gonorrhoea and syphilis infections are once again posing a threat to public health. In addition, the antibiotic sensitivity pattern for gonorrhoea appears to have changed with an increased prevalence of resistance. Both syphilis and gonorrhoea appear to disproportionately affect MSM and black ethnic minorities, and are concentr...
