Getting tested for STIs is straightforward and more accessible than most people expect. You can get tested at a doctor’s office, a sexual health clinic, a community health center, or even at home with a mail-in kit. The process typically involves providing a urine sample, a blood sample, or a swab, and results come back within minutes to a few days depending on the test type.
Where to Get Tested
You have several options, and the best one depends on your budget, privacy preferences, and what you’re testing for.
Your primary care doctor or gynecologist can order a full STI panel during a regular visit. This is often the simplest route if you already have a provider and insurance. Planned Parenthood and similar reproductive health clinics offer testing on a walk-in or appointment basis, often on a sliding fee scale. County and city sexual health clinics are another option. Some charge a flat fee that covers testing, treatment, and follow-up visits. San Diego County’s clinics, for example, charge $40 per visit for a comprehensive panel including lab work, treatment, and vaccinations, and they’ll waive the fee if you can’t pay. HIV testing at many public clinics is free.
Urgent care centers can also run STI tests, though they tend to cost more and may not test for every infection unless you ask specifically.
At-Home Testing Kits
If you’d rather skip the clinic entirely, FDA-cleared home test kits let you collect your own samples and mail them to a lab. Self-collection options now exist for HIV, syphilis, chlamydia, gonorrhea, and trichomoniasis. You collect a vaginal swab, urine sample, or finger-prick blood sample at home, send it off, and get results in a few days.
These kits are reliable. The first FDA-authorized home test for chlamydia, gonorrhea, and trichomoniasis (the Visby Medical test for vaginal samples) correctly identified 97.2% of positive chlamydia samples, 100% of positive gonorrhea samples, and 97.8% of positive trichomoniasis samples. Some programs even offer free home testing kits. The CDC-affiliated TakeMeHome program provides free kits for HIV, chlamydia, gonorrhea, syphilis, and hepatitis C to people who haven’t been tested in the past year.
There are also rapid self-tests for HIV and syphilis that give you results at home without mailing anything. A positive result on a self-test still needs to be confirmed with a follow-up lab test.
What the Tests Involve
STI testing is not one single test. Different infections require different specimens, and your provider will choose based on what you’re screening for and your sexual history.
- Chlamydia and gonorrhea: Urine sample or a swab of the vagina, rectum, or throat. If you’ve had oral or anal sex, make sure to mention it so the right sites get tested. A urine-only test will miss infections in the throat or rectum.
- HIV: Blood draw or an oral cheek swab. Rapid finger-prick tests give results in about 20 minutes. Standard blood tests sent to a lab are more sensitive, especially soon after exposure.
- Syphilis: Blood test. Rapid point-of-care versions return results in about 10 minutes.
- Hepatitis C: Blood test.
- Herpes: Usually tested only if you have active sores (swab of the sore) or by a blood test that checks for antibodies.
A “full panel” doesn’t always mean the same thing at every clinic. Ask what’s included. Many standard panels cover chlamydia, gonorrhea, syphilis, and HIV but skip herpes, hepatitis, and trichomoniasis unless you request them.
When to Wait Before Testing
Testing too soon after a possible exposure can produce a false negative. Every infection has a window period: the gap between when you’re exposed and when the test can reliably detect it.
- Chlamydia and gonorrhea: One week catches most cases. Two weeks catches nearly all.
- HIV (blood test, antigen/antibody method): Two weeks catches most. Six weeks catches nearly all.
- HIV (oral swab): One month catches most. Three months catches nearly all.
- Syphilis: One month catches most. Three months catches nearly all.
If you had a specific exposure you’re worried about, testing at two weeks will catch chlamydia and gonorrhea. For HIV and syphilis, you may need to test again at the six-week or three-month mark to be fully confident in the result.
How Often to Get Tested
The CDC recommends all adults ages 13 to 64 get tested for HIV at least once. Beyond that, the frequency depends on your age, sex, and risk factors.
Sexually active women under 25 should be screened for chlamydia and gonorrhea annually. Women 25 and older need annual screening only if they have risk factors like new or multiple partners. All adults over 18 should be screened for hepatitis C at least once.
Men who have sex with men face higher rates of several STIs and should get tested for chlamydia, gonorrhea, syphilis, and HIV at least once a year. If you’re on PrEP, living with HIV, or you or your partners have multiple partners, testing every 3 to 6 months is recommended. Gonorrhea and chlamydia testing should include the throat and rectum based on sexual activity, not just a urine test.
During pregnancy, chlamydia, gonorrhea, syphilis, and HIV screening happens at the first prenatal visit. Retesting in the third trimester is recommended for those under 25 or with certain risk factors.
How Long Results Take
Rapid tests for HIV and syphilis deliver results in 10 to 20 minutes during your visit. These are common at sexual health clinics and community testing events.
Standard lab tests for chlamydia, gonorrhea, and other infections that require a specimen sent to a laboratory typically take one to five business days. Most clinics will call, text, or make results available through an online portal. Home collection kits follow a similar timeline once the lab receives your sample.
If You Test Positive
Chlamydia, gonorrhea, syphilis, and trichomoniasis are all curable with antibiotics. Many clinics will treat you the same day as your positive result or even at the initial visit if symptoms are present. HIV and herpes are not curable but are manageable with treatment that can keep viral levels undetectable or reduce outbreaks significantly.
Notifying past partners is an important step, and you don’t have to do it face to face. TellYourPartner.org lets you send an anonymous text to a sexual partner letting them know they may have been exposed. Studies show anonymous notification tools improve the rate at which partners actually get tested, which helps break the chain of transmission. Many local health departments also offer partner notification services where a public health worker contacts your partners without revealing your identity.
After treatment for chlamydia or gonorrhea, retesting in about three months is standard to make sure you haven’t been reinfected. A positive result doesn’t mean you did anything wrong. It means the test did exactly what it was supposed to do.
