After being infected with syphilis, TPPA usually turns positive first, which is a specific antibody test for syphilis; when the TPPA test is positive, it is necessary to do further TRUST test, which is a non-specific antibody test for syphilis.
In the early stage of clinical syphilis infection, once TPPA and TRUST are positive, early diagnosis and treatment should be carried out, with a regular process and adequate dosage.
TPPA is a syphilis-specific antibody test, while TRUST is a syphilis non-specific antibody test. When infected with syphilis, early syphilis-specific antibodies appear earlier than non-specific antibodies, so TPPA usually turns positive first.
After being infected with syphilis, it is necessary to go to the hospital as soon as possible to make a clear diagnosis, and the doctor will formulate an individualized diagnosis and treatment plan according to the specific condition, so as to avoid delaying the treatment.
