How Often Should You Get Tested for STDs?
Quick answer
CDC-aligned baseline: everyone sexually active under 25 gets chlamydia and gonorrhea screening yearly; everyone 13–64 tests for HIV at least once; women under 25 and men with new/multiple partners test annually or more. With new partners: before sex together. Multiple partners: every 3–6 months. Pregnant: first trimester panel. Monogamous and mutually tested: annually or less.
Your schedule by situation
| Your situation | Testing rhythm | Cover |
|---|---|---|
| Sexually active woman <25 | Yearly | Chlamydia + gonorrhea (+HIV once minimum) |
| New partner | Before unprotected sex, then per exposure | Full panel both partners |
| Multiple/overlapping partners | Every 3–6 months | Full panel incl. site-specific swabs |
| Gay/bi men, on PrEP | Every 3 months | HIV + syphilis + gono/chlam (all sites) |
| Pregnant | Early pregnancy; repeat by risk | Syphilis, HIV, hep B/C, chlamydia/gonorrhea |
| Treated infection recently | Retest at 3 months | The treated infections |
| Mutually tested monogamy | Yearly or when circumstances change | Baseline maintenance |
Why 3–6 months for higher-risk patterns
Three reasons the interval shortens with exposure frequency:
- Reinfection cycles: successfully cured people re-acquire from untreated partners at high rates — CDC recommends retesting all treated persons at three months.
- Silent progression: quarterly screening catches infections while they're still easy cures rather than fertility threats.
- Window-period math: frequent testing plus known windows means no single negative gets trusted too long.
Trigger events override calendars: a condom break, a partner's disclosure, symptoms appearing — these demand immediate testing regardless of your last date.
Making testing boring (the goal)
- Stack it: pair panels with birthdays, daylight-saving changes, or dental cleanings.
- Use reminders: calendar invites titled something neutral work fine.
- Keep one venue: same lab each time builds speed and comfort.
- Normalize the ask: "when were you last tested?" belongs in early dating conversations alongside "what are you looking for?"
Venue selection and logistics live in where to get tested; budget planning in cost guide.
Frequently asked questions
How often should I get tested if I'm in a relationship?
Mutually tested monogamous couples can drop to annual maintenance — or pause entirely after confirming status, resuming when circumstances change.
How often do gay men need STI screening?
CDC advises at least annual screening; every 3 months for those on PrEP or with multiple partners, covering all exposure sites.
Is yearly enough for chlamydia screening?
For women under 25, yes — annual is the guideline. More frequently with new partners, symptoms, or post-treatment rechecks at 3 months.
When should I retest after treatment?
Gonorrhea: test-of-cure around 2 weeks post-treatment. Everyone treated: full retest at 3 months to catch reinfection.
