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). (wikipedia.org)
This test is done routinely to confirm whether a positive screening test for syphilis (either VDRL or RPR ) means you have a current syphilis infection. (medlineplus.gov)
All positive RPR and VDRL test results should prompt follow-up with FTA-ABS or TP-PA. (medscape.com)
Biologic false-positive results are defined as a positive RPR/VDRL result with a negative FTA-ABS/TP-PA result and are due to reactivity of autoantibodies to the cardiolipin-lecithin-cholesterol reagent present in the nontreponemal tests. (medscape.com)
RPR and VDRL titers are not interchangeable or convertible, so it is important to use consistent testing with a single method to monitor disease activity. (medscape.com)
