The VDRL test is a screening test for syphilis. It measures substances, called antibodies, that your body may produce if you have come in contact with the bacteria that causes syphilis. This bacteria is called Treponema pallidum. The test is similar to the newer rapid plasma reagin (RPR) test.

Your doctor will most likely order a VDRL test if there is a chance of having syphilis. Early symptoms that may prompt your doctor to order this test include:
One small, painless sore swelling in lymph nodes near the sore.
A skin rash that doesn?t itch.
In other cases, your doctor may screen for syphilis even if you don?t have any symptoms or reasons to think you have the disease. For example, your doctor will screen for syphilis as a routine part of your care if you?re pregnant. This is a standard procedure, and it doesn?t mean your doctor thinks you have syphilis.
Your doctor may also test you for syphilis if you?re being treated for another STI such as gonorrhea, if you?re infected with HIV, or if you?ve engaged in high-risk sexual activity. The Centers for Disease Control and Prevention (CDC) also recommends follow-up testing if you have been treated for syphilis to be sure that the treatment worked and the infection has been cured.
