Neisseria gonorrhoeae (GC) is a common sexually transmitted infection and may be asymptomatic. N. gonorrhoeae primarily causes a lower genital tract infection, but if untreated, may cause disseminated disease or pelvic inflammatory disease with endometritis, salpingitis, pelvic peritonitis, and tubo-ovarian abscesses.
This test should be ordered in patients with symptoms of cervicitis or urethritis, as well as for screening asymptomatic patients.
