SpletCadham Provincial Lab (CPL): VDRL, FTA-ABS and syphilis PCR Non-treponemal test: VDRL • If reactive, i.e. 1 dilution or higher, then it is confirmatory for neurosyphilis Treponemal test: fluorescent treponemal antibody absorption (FTA-ABS) • Often reactive, but it is more sensitive and less specific than VDRL • Automatically run after VDRL SpletThe VDRL is a nontreponemal serological screening for syphilis that is also used to assess response to therapy, to detect central nervous system involvement, and as an aid in the …
SpletNon-treponemal assays, such as rapid plasma reagin (RPR) and Venereal Disease Research Laboratory (VDRL) assays, detect the reactivity of antibodies in serum or cerebrospinal fluid (CSF) against cardiolipin-cholesterol-lecithin antigens, which, though not specific to T. pallidum, are present in most patients with syphilis. Further testing with CSF evaluation is warranted for persons with clinical signs of neurosyphilis (e.g., cranial nerve dysfunction, meningitis, stroke, acute or chronic altered mental status, or loss of vibration sense).

SpletBackground. Syphilis is a sexually transmitted disease (STD) caused by the bacterium Treponema pallidum. Syphilis is passed from person to person through direct contact with a syphilitic chancre. Chancres occur mainly on the external genitals, vagina, anus, or in the rectum but can also occur on the lips and in the mouth. SpletThe CSF-VDRL syphilis test is not an appropriate screening test because, although specific, it is not sensitive. A negative result can also occur in some neurosyphilis patients, so the test cannot be used to rule out neurosyphilis. The Centers for Disease Control recommend that the CSF-VDRL be performed ONLY when a patient has a seropositive ...
Splet27. sep. 2024 · In addition, asymptomatic patients should be screened for syphilis if they are at high risk for having acquired disease or for transmitting disease to others. Serologic testing is generally used to make a diagnosis of syphilis. The approach to testing is described below. (See 'Approach to testing' below.)
SpletBecause these tests measure the host's antibody response to nontreponemal antigens, they may lack specificity. Therefore, a positive result by RPR or VDRL requires confirmation by a treponemal-specific test, such as the T pallidum particle agglutination (TP-PA) assay. Although technically simple to perform, the TP-PA assay is labor intensive ... adobe reader digital signature cacSpletThe VDRL test in CSF has high specificity but low sensitivity. A negative CSF VDRL therefore does not rule our neurosyphilis. The sensitivity of the test can be increased by testing only patients with documented infection with Treponema pallidum.
