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. The VDRL test is used to screen for syphilis (it has high sensitivity ), whereas other, more specific tests are used to diagnose the disease.
The fluorescent treponemal antibody absorption (FTA-ABS) test is a diagnostic test for syphilis.Using antibodies specific for the Treponema pallidum species, such tests would be assumed to be more specific than non-treponemal testing such as VDRL but have been shown repeatedly to be sensitive but not specific for the diagnosis of neurosyphilis in cerebrospinal fluid (CSF).
Nontreponemal tests are screening tests, very rapid and relatively simple, but need to be confirmed by treponemal tests. [1] Centers for Disease Control and Prevention (CDC)-approved standard tests include the VDRL test (a slide test), the rapid plasma reagin (RPR) test (a card test), the unheated serum reagin (USR) test, and the toluidine red ...
Developed by privately held NOWDiagnostics, the antibody test helps identify current or past infection and provides a result in about 15 minutes. However, the regulator added that the results from ...
Another test often used to screen for syphilis is the Venereal Disease Research Laboratory (VDRL) slide test. However, the RPR test is generally preferred due to its ease of use. Other types of tests are being evaluated as possible alternatives to standard manual RPR testing. One of these alternatives is a fully automated RPR syphilis analyzer. [3]
The FDA just approved the first at-home test to detect syphilis antibodies, which will make it easier for people to screen themselves for this sexually transmitted disease. The test from ...
