2020年12月5日 · The VDRL (Venereal Disease Research Laboratory) test is a screening test for syphilis that detects antibodies produced against antigens released by damaged host cells in patients infected with Treponema pallidum, the bacterium that causes syphilis.

2022年4月26日 · A brief overview of syphilis and an outlook on the frequently requested VDRL test. An insight into other investigative modalities for the diagnosis of syphilis.

2015年8月14日 · It describes direct detection methods like darkfield microscopy and fluorescent antibody testing to visualize the bacterium in samples. It also covers non-treponemal tests that …

2011年4月3日 · VDRL – A Standard Test for Syphilis • The VDRL can be used for qualitative and quantitative measurements and is recommended when a patient suspected of having syphilis has a negative dark field microscopy result or when atypical lesions are present.

2014年9月6日 · Diagnostic Evaluation • The diagnosis of syphilis is based on the clinical picture in conjunction with demonstration of microorganisms in a lesion and serologic testing. • Darkfield Microscopy • Nontreponemal Methods- Venereal Disease Research Laboratory (VDRL) and the Rapid Plasma Reagin (RPR) procedures are used to screen patient’s serum.

This document provides information on serological tests for syphilis, including the VDRL, RPR, FTA-ABS, and TP-MHA tests. It describes what each test is, how it works, its accuracy, limitations, and role in screening and diagnosing syphilis.

What is a VDRL test? The venereal sickness explore research facility (VDRL) test is intended to survey whether you have syphilis, a sexually transmitted contamination (STI). Syphilis is caused by the bacterium Treponema pallidum. The bacterium taints by entering into the coating of the mouth or genital territory. The VDRL test doesn't search ...

How can we test for Syphilis? Traditionally screening was done with a non-treponemal test such as RPR or VDRL. Some smaller labs with low volumes still do this. Now vast majority of labs screen with a treponemal test and then confirm with a non-treponemal test. What problems might this lead to? How can we test for Syphilis?

2014年2月15日 · Direct tests include dark-field microscopy, direct fluorescent antibody testing, and PCR to identify the bacterium in lesions. Serological tests include non-treponemal tests like VDRL and RPR that detect nonspecific reagin antibodies, and treponemal tests like FTA-ABS, TPHA, and EIA that detect treponema-specific antibodies. 3.
