Serum RPR (Rapid Plasma Reagin) and VDRL (Venereal Disease Research Laboratory) tests are used to screen for syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum.
When this Serum RPR/VDRL test is required
These tests may be requested when a person shows signs or symptoms of syphilis, such as genital sores, skin rash, fever, swollen lymph nodes, and sore throat. They may also be ordered as part of routine screening during pregnancy or as part of a sexual health check-up.
What the Serum RPR/VDRL Test Detects
These tests detect the presence of antibodies produced by the body in response to a syphilis infection. The RPR test measures antibodies in the blood that react with a substance called cardiolipin. The VDRL test measures antibodies that react with a substance called reagin.
Preparation for the Serum RPR/VDRL Test
No special preparation is required for these tests.
Sample Requirements
The test requires a blood sample, which is usually drawn from a vein in the arm.
Additional Notes
It is important to get treated promptly if syphilis is detected, as it can cause serious health problems if left untreated. It is also important to follow up with your healthcare provider for further testing and treatment if you have a positive test result.
