Chlamydia trachomatis NAAT- Provincial
Discipline
Microbiology
Overview
Description
- Chlamydia trachomatis infections are one of the most common sexually transmitted infections worldwide. They cause mostly uncomplicated lower urogenital tract infections that can lead to pelvic inflammatory disease when untreated. Certain serovars of Chlamydia trachomatis (LI, L2, L3) cause Lymphogranuloma venereum (LGV). The most sensitive and specific way to detect this pathogen is via a nucleic acid test.
Ordering Recommendations
- Sexually active patients who are symptomatic (urethral discharge, urethritis, vaginitis, cervicitis, pain)
- Pregnant women
- Patients at increased risk of STIs (multiple partners, sexual assault, high risk lifestyle)
- Suspect cases of LGV (should be indicated on requisition)
- Patients should simultaneously be tested for Chlamydia trachomatis and Neisseria gonorrhoeae as the presentations overlap
