In order to solve the problem that it is difficult for syphilis patients to be re-visited and unable to monitor the change of RPR titer for a long period of time, we have opened a green channel for syphilis patients since June 2014, and any patient who meets the requirements can see me for an additional number when I have an outpatient clinic (Monday to Friday morning, please ask the nurse at the triage desk for the specific clinic number). Please bring your personal laboratory tests (Rapid Syphilis Serum Reactive Protein Test or RPR and TPPA results). If you need to add a number, please bring your test results if you meet the following requirements 1. Patients with syphilis serum fixation, who have had syphilis in the past and whose RPR titers do not become negative after 1 or 2 years of penicillin treatment. (RPR test sheet shows 1:2, 1:4, 1:8, 1:16, 1:32 and does not show negative). 2. History of unclean sexual intercourse, recent ulcers on external genitalia, or red rash on palms and back of chest, not painful or itchy, RPR and TPPA results tested or not tested in external hospitals.
