What does the RPR test screen for?

The RPR test, which stands for Rapid Plasma Reagin, is specifically designed to screen for syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum. This test detects non-specific antibodies that may be present in the blood of individuals infected with syphilis, indicating a possible infection. The RPR test is often used as a preliminary screening tool, and if positive, it is typically followed by more specific tests to confirm the diagnosis of syphilis.

This focus on syphilis sets the RPR apart from screenings for other conditions, such as hepatitis, gonorrhea, or HIV, each of which has its own specific tests tailored to detect their respective pathogens or antibodies. Thus, understanding that the RPR is directly linked to syphilis testing is crucial for accurate diagnosis and effective patient care in the context of sexually transmitted infections.
