From the Research

Based on the CT/NG urine screen result of 40, treatment for both chlamydia and gonorrhea is recommended, as the most recent and highest quality study 1 suggests that point-of-care tests for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) can provide accurate diagnoses and guide immediate treatment. The current standard treatment is a single dose of ceftriaxone 500 mg intramuscularly PLUS doxycycline 100 mg orally twice daily for 7 days, as supported by the study 1. This combination therapy is effective against both infections and helps prevent the development of antibiotic resistance. Some key points to consider when treating patients with a CT/NG urine screen result of 40 include:

  • Treating all sexual partners from the past 60 days to prevent reinfection, as emphasized in the study 2
  • Patients should abstain from sexual activity until treatment is completed and all partners have been treated, as recommended in the study 3
  • A follow-up test should be performed 3 months after treatment to ensure the infection has cleared, as suggested in the study 4 This approach is recommended because the test result doesn't specify which infection is present, and co-infection is common, as noted in the study 5. Treating both infections simultaneously is the most effective way to ensure complete cure and prevent complications.
