Testing for chlamydia and gonorrhea

SiteApproach for asymptomatic patients or screeningApproach for symptomatic patients
Penile urethra
  • First-void urine for NAAT for chlamydia and gonorrhea

  • Urethral swab for gonorrhea culture and sensitivity testing, and first-void urine for NAAT for chlamydia and gonorrhea

Cervix or vagina*
  • Vaginal swab (preferred), cervical swab or first-void urine for NAAT for chlamydia and gonorrhea

  • Cervical swab for gonorrhea culture and sensitivity testing, and for NAAT for chlamydia and gonorrhea, or

  • Vaginal swab for gonorrhea culture and sensitivity testing, and for NAAT for chlamydia and gonorrhea, or

  • First-void urine for NAAT for chlamydia and gonorrhea

Throat
  • Throat swab for NAAT for chlamydia and gonorrhea

  • Throat swab for gonorrhea culture and sensitivity testing, and for NAAT for chlamydia and gonorrhea

Rectum
  • Rectal swab for NAAT for chlamydia and gonorrhea

  • Rectal swab for gonorrhea culture and sensitivity testing, and for NAAT for chlamydia and gonorrhea

  • Note: NAAT = nucleic acid amplification test.

  • * For patients with a neovagina, a first-void urine is the preferred screening test. In symptomatic patients, efforts should be made to conduct gonorrhea culture and sensitivity testing, as well as NAAT for chlamydia and gonorrhea. When culture and sensitivity testing is not possible, either a cervical or vaginal swab for NAAT or a first-void urine is appropriate.
