Laboratory: Clinical Microbiology
Test Name:
Test Code: GC
Clinical Information:
Test Indications:
Patients with suspected gonorrhoeae due to symptomatic urethral or cervical, discharge, rectal or pharyngeal complaints, at-risk sexual behavior, sexual assault or known exposure when culture is preferred over nucleic acid detection. This includes:
1. Suspected treatment failure
2. Disease acquired in a country with high resistance rates
3. Symptomatic man who has sex with men.
4. Rectal or pharyngeal gonorrhoeae
5. Sexual assault
6. Requirement for susceptibility testing
7. Suspected pelvic inflammatory disease

Specimens from women should include a cervical swab from women with a cervix, or vaginal vault swab for women without a cervix. Vaginal swabs are acceptable from pediatric female patients. Submit a urethral swab from adult and pediatric males, or women with suspected gonorrhoeae and predominantly dysuric symptoms. All patients who report receptive anal intercourse or women who have anorectal symptoms (regardless of anal sex history) should have rectal swabs submitted for culture. All patients with a history of receptive oral intercourse should have a throat swab submitted for culture. The performance of this test for transgendered populations is not known. Transgendered females should have both urethral and neovaginal (if present) swabs submitted with pharyngeal or rectal swabs as indicated above. Transgendered males should have a urethral, cervical (if present) or vaginal swab (if present and no cervix present) submitted with pharyngeal or rectal swabs as indicated above.

Patient Preparation Instructions:
Not applicable.
