What does RPR non reactive mean?
Moreover, what does a non reactive syphilis test mean?
A negative or nonreactive result means you don't have syphilis. Positive results are given as a ratio in titers. This tells your healthcare provider the amount of antibodies in your blood. If you have a history of syphilis and your RPR test is negative or nonreactive, it is likely that you no longer have syphilis.
Subsequently, question is, why would RPR be reactive? A normal RPR blood sample shows no antibodies typically produced during an infection. One reason for a false positive is the presence of another disease that produces antibodies similar to the ones produced during a syphilis infection. A few of the conditions that can cause a false positive include the following: HIV.
Also asked, what does a reactive RPR mean?
RPR test: Rapid plasma reagin, a blood test for syphilis that looks for an antibody that is present in the bloodstream when a patient has syphilis. A negative (nonreactive) RPR is compatible with a person not having syphilis, but in the early stages of the disease, the RPR often gives false negative results.
Why is RPR nonspecific?
Reagin is not a specific antibody to Treponema pallidum, but is an IgM antibody to tissue lipids. RPR titers drop rapidly after treatment of primary or secondary syphilis, while the FTA-ABS remains reactive, irrespective of treatment. RPR is not highly specific.
