The RPR screening test is similar to the older VDRL test as both measure reaginic antibodies. These antibodies are usually produced during infection with syphilis as a result of the body’s interaction with the bacteria which causes syphilis (Treponema pallidum). This test is a useful screening tool for Syphilis, yet its ability to detect syphilis depends on the stage of the disease.
