Syphilis is the sexually transmitted infection (STI) that is caused by a type of bacteria known as Treponema pallidum. It is a type of infection which can be easily cured but can be serious in case it is not treated at the right time.
Testing of syphilis is done on blood, body fluid, or tissue samples.
The screening test is done when a person shows the signs of syphilis. The confirmation test can be done to confirm syphilis infection.
- Venereal Disease Research Laboratory (VDRL) Test
VDRL is done using the blood of the spinal fluid sample to check the presence of an antibody in the person that is produced against syphilis.
Testing the sample of Blood:
Through the blood test, one can confirm the presence of the antibodies that are produced to fight against the infection. The best part of the blood test is that antibodies produced in the body against the syphilis infection will remain in the body of several years. Hence, the test is used to determine past infection in a person.
Testing the Cerebrospinal fluid
The physician would suggest for a lumbar puncture or spinal tap for the collection of cerebrospinal fluid for testing if you are suspected of any nervous system complications due to syphilis.
- Rapid Plasma Regain (RPR) test
The RPR test also helps to find the presence of syphilis antibodies.
- Rapid Immuno-chromatographic test
Rapid Immuno-chromatographic test helps in examining the antibodies specifically to syphilis.
Confirmation Tests Syphilis
- Enzyme Immunoassay (EIA) tests
EIA blood test checks for syphilis antibodies. A positive EIA test should be confirmed with either the VDRL or RPR tests.
- Fluorescent Treponemal Antibody Absorption (FTA-ABS) test
FTA-ABS test also checks the presence for antibodies either in blood or spinal fluid. It is the syphilis test done after the first 3 to 4 weeks of exposure.
- Treponema Pallidum Particle Agglutination Assay (TPPA)
TPPA test is done when the other tests results show as positive for syphilis. The test is also done to confirm the presence of antibodies in the blood. TPPA test is not done on spinal fluid.
- Darkfield microscopy
Darkfield Microscopy test is done using a special microscope to look for the syphilis germ in either the sample of fluid or tissue that is taken from an open sore. This test can also be done even in the early stages of diagnosis.
- Microhemagglutination assay (MHA-TP)
The MHA-TP is a method of confirmation of syphilis infection after other tests give a positive result for syphilis in a person.
If you doubt syphilis infection, it is extremely vital to get the STD test done immediately. Various treatment methods can be done when your result shows positive for Syphilis, including the antibiotics injections or course of capsule for two or four weeks. Treatment course will depend on the duration of your infection.
