Syphilis is a sexually transmitted bacterial infection. 102 synonyms for test: check, try, investigate, assess, research, prove, analyse, experiment with, try out, verify, assay, put something to the proof.... What are synonyms for VDRL test? A microflocculation test for syphilis using cardiolopin antigen: preliminary report. A negative (nonreactive) VDRL is compatible with a person not having syphilis, but in the early stages of the disease, the VDRL often gives false negative results. It therefore detects anti-cardiolipin antibodies (IgG, IgM or IgA), visualized through foaming of the test tube fluid, or "flocculation". Contact the laboratory prior to submission of urgent clinical specimens. [4] Treponema pallidum particle agglutination assay (TP-PA) and the Toluidine red unheated serum test (TRUST), which may be used to confirm a positive VDRL result, are more specific for syphilis than non-treponemal tests and in the presence of a positive test, more likely indicate active infection. [3] This test is very useful as the trend of titres are correlated to disease activity (i.e. The rapid plasma reagin (RPR) test is a blood test that looks for antibodies to syphilis.

[citation needed], The MHA-TP is used to confirm a syphilis infection after another method tests positive for the syphilis bacteria. A positive VDRL in a spinal fluid uncontaminated by serum is essentially diagnostic of neurosyphilis; however, a negative test may occur in 30% of patients with tabes dorsalis. If the test is positive, the next step is to confirm the results with an FTA-ABS test, which is a more specific syphilis test. The VDRL test performed on cerebrospinal fluid (CSF) can be used to diagnose neurosyphilis in patients with a prior history of syphilis infection.
