STI testing follows the contact

Many STIs cause no symptoms. The useful testing conversation starts with what kind of contact happened, which body sites were involved, when it happened, and what prevention was used.

The one idea to keepA urine test or vaginal swab does not automatically test every infection or every exposed body site.
A patient and clinician review throat, urine, vaginal, blood, and rectal testing options based on exposed body sites.

01

Name the sites

Oral, vaginal, anal, and genital skin-to-skin contact can create different testing needs. A throat or rectal swab may be relevant when those sites were exposed.

  • Symptoms are not required
  • Testing windows differ
  • Ask what each sample checks
02

Prevention is layered

Condoms and barriers, vaccination, testing, fewer exposures, mutually agreed relationship practices, and HIV prevention options can work together.

  • Birth control is not STI protection
  • Skin-to-skin infections may spread beyond condom coverage
  • A new barrier is needed between body sites
03

Make the visit easier

A clinician needs practical information, not a moral story. You can say what body parts touched, what barriers were used, and what you want tested.

  • Ask about self-collected swabs
  • Ask when to retest
  • Pregnancy changes some testing priorities
