VDRL Test Means

VDRL Test is a blood test used to screen for syphilis.

  • VDRL Test detects the presence of antibodies produced in response to the syphilis bacteria.
  • A positive VDRL test indicates the presence of syphilis infection.
  • It is an initial screening test and further confirmatory tests are needed for a definitive diagnosis.
  • VDRL Test in pregnancy is also commonly performed to screen for syphilis infection in expectant mothers, as untreated syphilis can pose serious health risks to both the mother and the baby.

 

VDRL Test Purpose

Here are the purposes of the VDRL Test.

  • The VDRL test is commonly used to diagnose syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum.
  • The VDRL test is also used as a screening tool to detect syphilis in people who may not have any symptoms but are at risk of infection.
  • It can be used to monitor the effectiveness of treatment for syphilis. A decrease in the titer (level) of antibodies in the blood indicates that treatment is working.
  • If the VDRL test is positive, a confirmatory test such as the Treponemal Pallidum Antibody (TP-PA) test is usually done to confirm the diagnosis of syphilis.
  • The VDRL test may be used to test for other conditions that can cause false positive results on a syphilis test, such as lupus and rheumatoid arthritis.

  • A tourniquet will be tied around your upper arm to help locate a vein and make it easier to draw blood.
  • A needle will be inserted into the vein, and a small amount of blood will be drawn into a sterile tube.
  • After the needle is removed, a cotton ball or bandage will be placed over the site to stop any bleeding.

  • A non-reactive or negative VDRL test result means that no syphilis antibodies were detected in your blood.
  • A reactive or positive VDRL test result means that syphilis antibodies were detected in your blood.
  • A reactive VDRL test may indicate a current or past infection with syphilis. However, false positive results are possible, and additional tests are needed to confirm a diagnosis.
  • If your VDRL test is positive, your healthcare provider will recommend additional tests to confirm the diagnosis and begin treatment if necessary.
  • If you have a history of syphilis or have been treated for syphilis, a VDRL test may remain positive even if you are no longer infected.

VDRL Test FAQ

What is a VDRL Test?

  • The VDRL (Venereal Disease Research Laboratory) test is a blood test used to screen for syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum.
  • It detects the presence of antibodies produced by the body in response to a syphilis infection.

Why is a VDRL Test done?

  • The VDRL Test is performed to screen for syphilis in individuals who may have been exposed to the infection.
  • It is commonly included in routine prenatal testing to detect syphilis in pregnant women, as the infection can be transmitted from mother to baby during pregnancy and lead to severe complications.
  • The test is also used for diagnosing and monitoring the treatment of syphilis in individuals with symptoms or known exposure.

How is a VDRL Test performed?

  • The VDRL Test involves a blood sample taken from a vein, usually from the arm.
  • The blood sample is then sent to a laboratory for analysis.
  • In the laboratory, the sample is mixed with a solution containing substances that react with syphilis antibodies. The reaction is observed, and the results are reported as reactive (positive) or non-reactive (negative).

How to interpret the results of a VDRL Test?

A non-reactive (negative) VDRL Test result typically indicates the absence of syphilis antibodies in the blood, suggesting no current infection.

  • However, it's important to note that the test may not detect early-stage or recent infections.
  • Follow-up testing may be necessary if there is a suspicion of recent exposure.
  • A reactive (positive) VDRL Test result indicates the presence of syphilis antibodies in the blood.
  • Further testing, such as confirmatory tests (e.g., treponemal tests) and clinical evaluation, is needed to confirm the diagnosis and determine the stage of the infection.
  • Positive results should be reported to a healthcare provider for appropriate treatment and management.
