Sexually transmitted infections (STIs) often don’t show symptoms right away — or at all.
That’s why knowing when to get an STI test is crucial. Testing at the right time helps you detect infections early, prevent

Why Timing Matters for STI Testing
“Testing too early can produce false negatives — but waiting too long can lead to serious health issues.”
Timing your STI test correctly ensures accurate results and early treatment if needed.
Each infection has a “window period” — the time between exposure and when a test can reliably detect it.
Testing within the right window helps ensure you get accurate results the first time.
Bolded tips:
- Always test after a new partner or unprotected sex.
- If you have symptoms, get tested immediately.
- If you’re unsure, your clinician at SESH Clinic can help determine the best testing schedule for you.
Understanding the Window Periods for Common STIs
| STI / Infection | Typical Window Period | Testing Method | Retest Needed? |
| HIV (3th Gen Test | 3–4 weeks (confirm at 3 months) | Blood test | Yes |
| Chlamydia & Gonorrhea | 1–2 weeks | Urine / Swab | Sometimes |
| Syphilis | 3–12 weeks | Blood test | Yes |
| Herpes (HSV 1 & 2) | 3–6 weeks | Urine / Swab | Yes |
| Hepatitis B & C | 4–10 weeks | Blood test | Yes |
Tip: If you test negative but were exposed recently, retest after the full window period.
See CDC STI Testing Guidelines for more information.
When Should You Get an STI Test Immediately?
You should get tested as soon as possible if:
- You’ve had unprotected sex or a condom broke
- You’ve started a new relationship
- You or your partner have multiple partners
- You’ve noticed burning, sores, discharge, or unusual odor
- Your partner has been diagnosed with an STI
- You’re pregnant or planning pregnancy
How Often Should You Get an STI Test?
| Risk Level | Recommended Testing Frequency |
| Low Risk (monogamous, consistent condom use) | Every 12 months |
| Moderate Risk (occasional new partners) | Every 6–12 months |
| High Risk (multiple partners, MSM, on PrEP) | Every 3 months |
| Pregnant individuals | First trimester, and retest in 3rd trimester |
Tip: After an STI diagnosis, it’s best to retest 3 months after treatment to ensure full recovery.
