Common bacterial STIs
Often tested using swabs and/or urine (depending on infection and exposure site). Many are treatable, and early testing + treatment matters.
- Chlamydia
- Gonorrhea
- Syphilis (blood test)
STI testing: get the right test at the right time.
“STD testing” is often used as a general term, but different infections need different tests and timing. This site explains how to think about screening, window periods, symptoms, and choosing reliable providers.
- What “STI” vs “STD” means (and why it matters for screening).
- Home test vs clinic: accuracy, logistics, and follow-up.
- Timing after exposure: why some tests require waiting.
- Privacy considerations and what to look for in policies.
If you have symptoms, severe pain, fever, or you feel unsafe, seek medical care promptly.
What to test for (general overview)
The right tests depend on your exposure type, symptoms, partners, and prior results. This page is educational and not personalized medical advice.
Common viral infections
Testing approach varies: blood tests, swabs from lesions, or specific screening strategies depending on region and guidelines.
- HIV (blood/rapid tests, depending on type)
- HSV (herpes) (context-dependent)
- Hepatitis B/C (blood tests)
When “a panel” makes sense
Many services offer multi-test panels. Panels are useful when you want broad screening, but they still must match timing and exposure.
- Check what’s included (and what’s not).
- Confirm sample type (swab/urine/blood).
- Ensure results include clear next steps.
Timing & window periods (why “too early” happens)
After exposure, some infections may not be detectable immediately. That detection delay is often called a “window period.”
- Exposure → infection → detectability is not instant for many tests.
- Symptoms are not required for an infection to be present.
- Negative tests early sometimes need re-testing later.
- Clinic guidance matters if you are anxious, symptomatic, or high-risk.
If you need a clear plan, talk to a sexual health clinic or doctor for timing guidance tailored to your situation.
Home STI tests vs clinic testing
Home tests can be convenient, but you should know what “home test” actually means.
Home collection + lab processing
You collect a sample at home and send it to a lab. Reliability depends on sample collection quality and lab methods.
- Often more robust than self-read rapid tests.
- Good for privacy and convenience.
- Confirm how results are delivered and supported.
Rapid self-tests
Some tests are read at home. These can be useful in specific scenarios, but they have limitations and may need confirmation.
- Convenient and quick.
- Not available for every infection.
- False negatives/positives can occur.
Clinics and sexual health services
Clinics can choose validated tests, collect appropriate samples, and arrange treatment/partner notification support where relevant.
- Best when you have symptoms.
- Clear follow-up and interpretation.
- May be required for certain confirmatory tests.
Privacy and sensitive health data
STI testing is sensitive. Before using any online service, verify how they store data and what deletion options exist.
Checklist
- Can you delete your account and results?
- Is data used for research or marketing?
- Is there a clear contact point for privacy requests?
