I have got my 4 weeks syphilis test results after the exposure .the TPPA and RPR test are all negative,but I take 12 pills of Azithromycin to cure my NGU during the 4 weeks,and I did not take the pills for 5 days before I take tke test.some one told me that the Azithromycin would cure the syphilis,and it will make the test result inaccurate,should I test syphilis again,and would the Azithromycin make the result inaccurate? thamk you
