What does RPR positive mean?

RPR is a serological test used to detect syphilis. A positive RPR result indicates a reactive outcome in this test, meaning non-treponemal antibodies against syphilis have been detected in the patient's serum. Patients are advised to seek medical evaluation promptly to determine the underlying cause and receive appropriate treatment. The detailed analysis is as follows:

When an individual undergoes an RPR test, a positive result means that non-treponemal antibodies have been detected in the serum. However, this does not definitively confirm a diagnosis of syphilis; rather, it suggests a possible syphilis infection or other conditions that may lead to the production of non-specific antibodies. Syphilis is a sexually transmitted infection caused by the bacterium *Treponema pallidum* and can be transmitted through sexual contact. The RPR test detects non-treponemal antibodies produced by the body, which may appear several weeks after infection. Nevertheless, the RPR test lacks sufficient specificity and may yield false-positive results due to other conditions such as other treponemal infections, autoimmune diseases, or pregnancy.

Therefore, a positive RPR result should be confirmed with additional testing methods, such as *Treponema pallidum* antibody tests, to improve diagnostic accuracy.
