The test for syphilis antibodies can be divided into two categories: specific and non-specific tests. tP refers to the syphilis spirochete, and a positive syphilis spirochete antibody means that the corresponding test finds it to be positive, generally referring to the particle agglutination test for syphilis spirochetes, or TPPA for short, or possibly the hemagglutination test for syphilis spirochetes, or TPHA for short. the principle of these two tests is the same, and both of their positivity Both tests are based on the same principle, and a positive result can identify a person with syphilis. Because this is a specific test, the possibility of a false positive is very low. So if the TPPA test is positive, it means that a person has syphilis. However, this only indicates that a person is a syphilis patient, it does not indicate whether treatment is currently needed, to what stage of syphilis, and these should depend on the patient’s symptoms. Non-specific tests for syphilis spirochetes are also needed, mainly the application of the rapid plasma reactin test, or the toluidine red unheated serum test, to see its titer as well as changes and to determine whether treatment is needed.
