Information about the VDRL  

We Have to Know about the VDRL 

  • VDRL is a screening test for syphilis that measures antibodies that can be produced by Treponema pallidum, the bacteria that causes syphilis.

How the Test is Performed:   

  • The test is usually performed on blood.
  • If a private is suspected of getting brain involved with the sexually transmitted disease (neurosyphilis), the VDRL takes a look at could also be performed on a bodily fluid.

How the Test Will Feel:       

  • When the badger is embedded to draw hemoglobin, you may sense moderate pain, / only a prick / stinging sensation. Afterward, there may be some throbbing.

Why the Test is Performed:   

  • This test is used to diagnose syphilis.
  • Syphilis is a highly treatable infection.
  • In addition to screening individuals with signs and symptoms of sexually transmitted diseases, syphilis screening is a routine part of prenatal care during pregnancy.

Normal Results:   

  • A negative take a look at is traditional and implies that no antibodies to sexually transmitted diseases are detected.
  • The screening test is most likely to be positive in secondary and latent syphilis. During primary and syphilis, this takes a look at could also be incorrectly negative.

What Abnormal Results Mean:   

  • A positive take a look at results might mean you have got sexually transmitted disease. If they take a look at is positive, the next step is to confirm the results with an FTA-ABS test, which is a more specific syphilis test.
  • The VDRL test’s ability to discover venereal Venus’s curse depends on the stage of the disease. The test’s sensitivity to discover sexually transmitted disease nears 100 percent throughout the center stages; its less sensitive throughout the sooner and later stages.

The following conditions may cause a false positive test:

  • HIV
  • Lyme disease
  • Certain types of pneumonia
  • Malaria
  • Systemic lupus erythematosus

Risks of VDRL    

  • Veins & arteries differ in size from one patient
     to a different and from one facet of the body to the opposite.
    Obtaining a blood sample from some individuals could also be harder than from others.

Other risks  related to having blood drawn are slight, however, might include:

  • Excessive bleeding
  • Fainting or feeling light-headed
  • Hematoma (blood accumulating under the skin)
  • Infection (a slight danger at any moment the membrane is broken)


  • The body doesn’t continuously manufacture antibodies specifically in response to the sexually transmitted disease bacterium, thus this takes a look at isn’t continuously correct.
