VDRL, Serum - The serum VDRL test is an aid in the diagnosis of syphilis. The predictive value of a reactive VDRL is increased when combined with a treponemal-specific test such as FTA or TP-PA. A reactive VDRL test on CSF, free of blood or other contaminants, usually suggests past or present syphilis infection of the central nervous system.

2018年9月29日 · 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...

The Venereal Disease Research Laboratory test (VDRL) is a blood test for syphilis and related non-venereal treponematoses that was developed by the eponymous US laboratory.

2020年2月24日 · The venereal disease research laboratory test (VDRL) is a blood test that can identify syphilis infections. Syphilis is one of the most common sexually transmitted infections (STIs).

2024年2月6日 · Studies of treponemal test sensitivity in CSF included patients with symptomatic and asymptomatic neurosyphilis; various laboratory tests were used for the reference standard, including CSF white blood cell count, protein, and CSF-VDRL (153).

This syphilis VDRL is a nontreponemal assay used to aid in the diagnosis of neurosyphilis. Agglutination. Nonreactive. A positive VDRL in a spinal fluid uncontaminated by serum is essentially diagnostic of neurosyphilis; however, a negative test …

A VDRL test measures antibodies that are often produced within one to two weeks after an infected person develops an initial sore. VDRL testing can be performed on blood or spinal fluid.

2022年7月31日 · The Venereal Disease Research Laboratory (VDRL) test is one of two variations of micro flocculation procedures used for serological testing of syphilis. Flocculation testing is based on antibody detection with the interaction of soluble antigen with an antibody that results in a precipitate formation of fine particles.

2023年8月30日 · The VDRL (Venereal Disease Research Laboratory) and TPHA (Treponema pallidum hemagglutination assay) tests are essential components of the serological screening and diagnosis of syphilis, a sexually transmitted infection (STI) caused by …

The Venereal Disease Research Laboratory (VDRL) test is a blood test designed to screen for syphilis. As a non-treponemal test, it identifies antibodies that the body produces in response to tissue damage caused by syphilis, rather than directly detecting the …
