Comparative Study of VDRL and TPHA and their Complementary

VDRL slide Meridian Healthcare. Among the serological tests for syphilis VDRL is the most inexpensive and commonly done test. In clinically unsuspected cases a reactive VDRL should always be checked with treponemal test like TPHA, FTA, ABS, TPI tests. TPHA test is routinely done in many laboratories in our country as a confirmatory test. Western reports regarding the comparison on VDRL and TPHA are few., VDRL Test full form is Venereal Disease Research Laboratory (VDRL) test. Thi s is a nonspecific flocculation test which is used for the screening of syphilis. VDRL test is easy to perform and inexpensive, so it is commonly used in the screening of population for syphilis ..

Primary Syphilis. All three screening tests (i.e., VDRL, TPHA, and EIA) have a sensitivity in the range of 70% to 80% in primary infection, and a few patients are negative in one test but positive in another. The use of ECOTEST-RPR as a diagnostic test is confronted by its false positivity. Thus, neither the ECOTEST-RPR nor the DIALAB-ELISA test stands on its own to be used either as screening or confirmatory test for syphilis diagnosis. Consequently, thorough studies should be conducted aiming on a change of the current diagnostic scheme in the community.

We read with great interest the CME article titled "VDRL ttest and its interpretation," which was published in March 2012 (2012; 57(1): 3-8) issue of Indian Journal of Dermatology. [1] The article very clearly and rightly conveyed the facts and misconceptions about this test and its interpretations in pregnant women and in cases of congenital syphilis, neurosyphilis and HIV infection.

    Widal test is a common agglutination test employed in the serological diagnosis of enteric fever. This test was developed by Georges Ferdinand Widal in 1896 and helps to detect presence of salmonella antibodies in a patient’s serum. The venereal disease research laboratory (VDRL) test is designed to assess whether you have syphilis, a sexually transmitted infection (STI). Syphilis is caused by the bacterium Treponema pallidum.

    According to its conclusion VDRL is the only test or the first in a series with the TPHA test (screening with VDRL and confirming with TPHA only the VDRL positives). If a general practitioner in the US wants to look for latent syphilis or for late active syphilis, he is expected to specially emphasize this on the request form or add SE 15.5% = (VDRL+ All 265 TPHA infected with T. uninfected The result of the VDRL/RPR is read as reactive or non-reactive and not as positive/negative. Although this has been made clear by the authors themselves but at number of places in the interpretation part of the article, the test results have been mentioned as positive or negative.

Viroj Wiwanitkit Department of Laboratory Medicine, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand Abstract. Syphilis serology is a basic screening test for the workers who want to go abroad. Many countries reject migrant workers who have reactive syphilis serology. Biological false reactives warrant repeated …

    Syphilis, which is caused by the bacterium Treponema pallidum, has often been called the “great imitator” because many of its signs and symptoms are indistinguishable from those of other diseases. Many refugees who are infected do not recall ever having had symptoms. Asymptomatic latent infection is detected through serologic screening. In 1896 and named after its inventor, Georges-Fernand Widal, is a presumptive serological test for enteric fever or undulant fever whereby bacteria causing typhoid and malaria fever (caused by protozoa) are mixed with a serum containing specific antibodies obtained from an infected individual. In cases of Salmonella infection, it is a demonstration of the presence of O-soma false-positive

Cockayne, in Medical Microbiology (Eighteenth Edition), 2012. Non-specific serological tests for syphilis. The rapid plasma reagin (RPR) test, which has now largely superseded the earlier Venereal Disease Research Laboratory (VDRL) test, is a non-specific serological test for syphilis that uses cardiolipin as antigen.
