Testing Of Syphilis

Syphilis is an infectious disease cause by bacterium and this disease won’t go own it’s own and can cause serious problem if it remained untreated and undiagnosed. You should get tested for syphilis infection if you are worried about having it. A sexual partner has been detected with syphilis or you are noticing some symptoms of syphilis infection. There are many different varieties of tests that can be done to check whether the person is having syphilis infection or not. The tests look for the antibodies of bacterium or the germs that are responsible for causing syphilis. Testing can be performed by using three things these are.

  • Blood
  • Tissue Sample
  • Body fluid like spinal fluid

There are two types of test that are performed to check whether a person is infected or not and these are 

  • Screening test
  • Confirmation test 

Screening Test: Tests that are used for screening syphilis are

    1. Venereal disease research laboratory (VDRL) test:This test looks for those antibodies that are produced by that body which is infected with syphilis bacteria by the use of spinal fluid or blood. 
    2. Rapid plasma reagin (RPR) test:This is another type of test which is performed to find syphilis antibodies.

Confirmation Test:After the screening test comes positive then a confirmatory test is needed. Confirmation test are of following types.

      1. Enzyme immunoassay (EIA) test: This blood test verifies the syphilis antibodies. A positive result of EIA test should be confirmed by either RPR or VDRL test.
      2. Fluorescent treponemal antibody absorption (FTA-ABS) test: This test is recommended to those patients who has been exposed that they are infected with syphilis for more than a month. To conduct this test blood sample or a spinal fluid is needed.
      3. Treponema pallidum particle agglutination assay (TPPA): this is a type of test which doesn’t need spinal fluid for testing. It also checks the presence of antibodies.
      4. Darkfield microscopy: In this test a special microscope is used to examine the syphilis germs in a sample of tissue or fluid from an open sore. This test is mainly used to diagnose syphilis in a premature stage.
