What is difference between syphilis and VDRL?

What is difference between syphilis and VDRL?

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. Rapid plasma reagin (RPR) test.

What causes VDRL positive?

The VDRL test is sometimes positive in the absence of syphilis. For example, a false positive VDRL can be encountered in infectious mononucleosis, lupus, the antiphospholipid antibody syndrome, hepatitis A, leprosy, malaria and, occasionally, pregnancy. The RPR (rapid plasma reagin) test is similar to the VDRL test.

What is a positive syphilis test?

A positive test result may mean that you have syphilis. If the screening test is positive, the next step is to confirm the diagnosis with a more specific test for syphilis, such as FTA-ABS . The FTA-ABS test will help distinguish between syphilis and other infections or conditions.

What does VDRL reactive mean?

A reactive CSF-VDRL test, free of blood or other contaminants, usually indicates past or present syphilis infection of the central nervous system (CNS). A BFP test result is rare in spinal fluid. A nonreactive VDRL test may indicate that the patient does not have neurosyphilis.

Is VDRL always positive?

The antibodies produced as a result of a syphilis infection can stay in your body even after your syphilis has been treated. This means you might always have positive results on this test.

How is VDRL positive treated?

The preferred treatment at all stages is penicillin, an antibiotic medication that can kill the organism that causes syphilis. If you’re allergic to penicillin, your doctor may suggest another antibiotic or recommend penicillin desensitization.

How do I know my VDRL is positive?

Understanding the results of your VDRL test 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.

Will I always test positive for syphilis?
