Chlamydia is the most common bacterial cause of sexually transmitted infection (STI) in both males and females. While the majority of patients are asymptomatic, the most frequent manifestation of uncomplicated C. trachomatis is urethritis in males and cervicitis in females. Proctitis, lymphogranuloma venerum, prostatitis, PID and other complications can also occur.
On all genital STI samples, Island Health uses a molecular STI Pathogen Panel that tests for Chlamydia trachomatis, Neisseria gonorrhoea and Trichomonas vaginalis. All requests for Chlamydia trachomatis and/or Neisseria gonorrhoea and/or Trichomonas vaginalis will result in testing for all three pathogens from any genital sample. The new combined assay is referred to as the STI Pathogen Panel and this is now the preferred order.
Preferred testing specimen varies by syndrome. Please ensure the correct STI swab is submitted to avoid rejection:
