: "Neisseria gonorrhoeae (NG) infections are the second most common communicable notifiable diseases in the United States. NG causes acute urethritis in males, which if untreated can progress to epididymitis, prostatitis, and urethral stricture. In females, the primary site of infection is the endocervix. An important complication in females is development of pelvic inflammatory disease, which contributes to infertility. Asymptomatic infections occur often in females but infrequently in males. Current methods for detection of NG include culture, non-amplified probes, and nucleic acid amplification tests (NAATs). NAATs have demonstrated two advantages over non-amplified methods: increased sensitivity and applicability to a variety of sample types, including urine. NAATs have been accepted as the preferred method for laboratory diagnosis of NG infections. In addition to testing for genital NG infections, recent CDC recommendations reflect the clinical utility of NAA-based NG testing of rectal and oropharyngeal specimens collected from patients at increased risk of infection at these extragenital sites, in particular, men who have sex with men.
