VDRL; RPR (Rapid Plasma Reagin) in Allahabad

The rapid plasma reagin (RPR) test is a blood test that looks for antibodies against a bacterial infection called syphilis. This test doesn't detect the actual bacteria that cause syphilis. Instead, it looks for antibodies against substances given off by cells that have been harmed by the bacteria.

It is used to screen for active syphilis infection and monitor response to treatment. Non-reactive RPR tests without clinical evidence of syphilis may suggest no current infection or an effectively treated infection. A false positive RPR (means positive results in the absence of syphilis) can be encountered in tuberculosis, malaria, and viral pneumonia. A reactive RPR test suggests past or present infections with the bacteria that cause syphilis. If not detected, syphilis can stay in the body for years and cause harm to internal organs.
