What does VDRL test mean?

VDRL is a blood testing method commonly used for rapid detection of syphilis. The detailed analysis is as follows:

The VDRL test determines whether a person is infected with syphilis by detecting the presence of antibodies against the syphilis-causing spirochete in the blood. This test is typically performed as part of syphilis screening and can help diagnose early syphilis infection. However, it cannot determine the duration of infection or the severity of the disease. For the VDRL test, a certain amount of blood sample must be collected, usually drawn from the patient's vein. The blood is then sent to a laboratory for analysis. If the result is positive, it indicates a possible syphilis infection, and further detailed examinations and diagnosis under a physician's guidance are required—such as the *Treponema pallidum* particle agglutination (TPPA) test—to confirm whether a true syphilis infection exists.

Syphilis is a sexually transmitted disease caused by spirochete bacteria that can damage multiple organ systems, including the skin, nervous system, cardiovascular system, and eyes. Once diagnosed, prompt targeted treatment under medical supervision is essential.
