What if VDRL test is positive?
A positive test result means you may have syphilis. If the test 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 detect syphilis depends on the stage of the disease.
What is the normal range of VDRL test?
Tertiary Syphilis RPR/VDRL: 85%-99% FTA-ABS/TP-PA/EIA: 96%
How do I know my Vdrl is positive?
If this occurs, your doctor will order a more specific test to confirm the results. A treponemal test is often used to confirm the positive test. Treponemal tests check whether your immune system has produced specific antibodies in direct response to the syphilis-causing Treponema pallidum.
What is VDRL test for syphilis?
Venereal disease research laboratory (VDRL) test. The VDRL test checks blood or spinal fluid for an antibody that can be produced in people who have syphilis. This antibody is not produced as a reaction to syphilis specifically, so the test result could be “abnormal” for reasons other than syphilis.
What syphilis means?
Syphilis is a bacterial infection usually spread by sexual contact. The disease starts as a painless sore — typically on the genitals, rectum or mouth. Syphilis spreads from person to person via skin or mucous membrane contact with these sores.
What type of bacteria causes syphilis?
Syphilis is a sexually transmitted disease (STD) caused by the bacterium Treponema pallidum.
What does Vdrl 1/32 mean?
This means that the RPR pr VDRL test remains reactive. The only way to know if it is an infection that needs treatment is to compare titers. If the titer is four fold lower than pervious (i.e. 1:128 down to 1:32), this means that the person has been appropriately treated and no further therapy is needed (CDC, 2010).
Is VDRL positive for life?
Other parameters, including VDRL results, can remain positive for more than a year after treatment of neurosyphilis.
