Quick Answer: Who Should Get Tested, and How Often

Most STIs cause no symptoms, so testing is often the only way to know your status. What you need tested and how often depends on several things working together: your age, which body parts are involved in sex (anatomy and exposure sites), your current sexual practices, whether you are pregnant, and where you live. It is not about picking a single identity label — a provider builds your testing plan from these specific factors, not from assumptions.

As a starting point, general guidelines include:

• Everyone ages 13 to 64 should be tested for HIV at least once as part of routine care.
• Most sexually active adults should be tested for syphilis, with frequency shaped partly by regional rates where they live.
• Pregnant women should be tested for syphilis, HIV, hepatitis B, and hepatitis C early in pregnancy; some also need chlamydia and gonorrhea testing and repeat testing later in pregnancy.
• Sexually active women under 25 should be tested for gonorrhea and chlamydia every year.
• Some women 25 and older should also be tested yearly for gonorrhea and chlamydia — for example, those with a new partner, multiple partners, or a partner known to have an STI.
• Sexually active gay and bisexual men and other men who have sex with men should be tested for syphilis, chlamydia, and gonorrhea at least once a year, with testing every 3 to 6 months if they have multiple or anonymous partners. The same more-frequent pattern applies to HIV testing for this group.
• Anyone who shares injection drug equipment should be tested for HIV at least once a year.
• Anyone who has had oral or anal sex should talk with a provider about whether throat or rectal testing is appropriate, since infections at those sites are not caught by a standard urine or blood test alone.

A healthcare provider is best positioned to translate these general guidelines into a specific plan for you. For more on why routine, symptom-independent screening is the standard approach, see our STI & Sexual Health guide. The checklist below helps you organize the information a provider will actually ask for, so your visit is efficient and your test menu matches your real exposure — not a guess.

Build Your Confidential Pre-Visit Checklist

You do not have to share this checklist with anyone but your provider. Writing it down beforehand — even just in your notes app — makes it easier to answer questions accurately and completely, especially if a visit feels rushed.

1. Anatomy and Exposure Sites

• What body parts are involved when you have sex (vagina, penis, mouth, anus)?
• Do you have a cervix? This affects whether cervical cancer screening applies alongside STI testing.
• Have you had oral sex, anal sex, vaginal sex, or a combination? Each exposure site may need its own swab, since a urine or blood test does not check the throat or rectum.

2. Symptoms (Describe, Do Not Self-Diagnose)

• Any unusual discharge, sores, bumps, itching, burning, or pain — note where and when it started.
• Symptoms are useful information for your provider, but many STIs cause no symptoms at all, and symptoms alone cannot confirm or rule out an infection. Testing is what confirms a diagnosis, not symptom-matching.

3. Partners and Practices

• Number of partners since your last test, and whether any were new or anonymous.
• Whether you or a partner have multiple concurrent partners.
• Whether a partner has been diagnosed with an STI or has symptoms.
• Condom or barrier use patterns — see our Birth Control & Contraception guide for how barrier methods factor into STI protection specifically, since not all contraception does.

4. Pregnancy Status

• Are you currently pregnant, trying to conceive, or unsure? Pregnancy changes which tests are recommended and how early they should happen, since some infections can affect a pregnancy if untreated.
• If pregnant, note how far along you are — some tests are repeated in the third trimester depending on risk factors.
• If you’re in the preconception stage, our Pregnancy & Preconception guide covers how STI screening typically fits into that broader visit.

5. Testing and Treatment History

• Date and results of your last STI test, and which infections were checked.
• Any past STI diagnoses and whether you completed treatment or a follow-up “test of support.”
• Whether you use injection drugs or share injection equipment.
• Whether you have HIV, are on PrEP, or have another condition that may call for more frequent screening.

Bringing this checklist to your appointment gives your provider what they need to recommend the right combination of tests the first time. Our Reproductive Health & Preventive Care guide has more on preparing for a visit like this.

Decision Path: Which General Guideline Applies to You?

These are population-level guidelines, not a diagnosis or a substitute for an individual conversation with a provider. More than one of these can apply to you at the same time — walk through each one.

• Are you between 13 and 64? HIV testing at least once is generally recommended as part of routine healthcare, regardless of other factors.
• Are you a sexually active woman under 25? Yearly gonorrhea and chlamydia testing is generally recommended.
• Are you a woman 25 or older with a new partner, multiple partners, or a partner with an STI? Annual gonorrhea and chlamydia testing may still apply — this is a conversation to have with a provider rather than something to rule out by age alone.
• Are you pregnant? Syphilis, HIV, hepatitis B, and hepatitis C testing is generally recommended early in pregnancy. Some pregnant women also need chlamydia and gonorrhea testing, plus repeat testing later in pregnancy if risk factors are present.
• Are you a gay or bisexual man, or another man who has sex with men? Syphilis, chlamydia, and gonorrhea testing at least once a year is generally recommended, moving to every 3 to 6 months with multiple or anonymous partners. The same more-frequent pattern applies to HIV testing.
• Do you share injection drug equipment? HIV testing at least once a year is generally recommended.
• Have you had oral or anal sex? Ask a provider whether throat and/or rectal testing should be added, since these sites require their own swabs and are not covered by a standard urine or blood test.
• Are you a sexually active adult generally? Syphilis testing is broadly recommended, with frequency also shaped by how common syphilis is where you live.

How STI Testing Works: Urine, Blood, and Swab Samples

Which sample type you provide depends on which infection is being checked and which body sites were exposed:

• Urine sample. Commonly used to test for chlamydia and gonorrhea in the urethra.
• Blood sample. Used for HIV, syphilis, and hepatitis B and C testing, and can also be used for some herpes antibody testing.
• Swabs. Vaginal, throat, or rectal swabs may be needed depending on which body parts were involved in sex. A urine or blood test alone will not detect an infection at the throat or rectum.

You may need more than one sample type in a single visit if your exposure involves more than one body site.

Self-Testing and Self-Collection Options

Beyond an in-office visit, there are two other confidential paths to get tested:

• Self-testing. You collect a sample yourself (a swab or a finger-prick blood sample) and use a device that gives results within minutes. FDA-approved self-test options exist for HIV and for syphilis, and an FDA-approved combined self-test for gonorrhea, chlamydia, and trichomoniasis is available using a vaginal swab.
• Self-collection kits. You collect a vaginal swab, urine sample, or blood sample at home using a kit, then mail it to a laboratory; results typically take a few days. FDA-approved self-collection options exist for HIV, syphilis, chlamydia, and gonorrhea.

Even if you use a self-test or self-collection kit, it’s worth having an open conversation with a healthcare provider about your results and your sexual history — self-testing does not replace that discussion, particularly if a result is positive or you have symptoms.

Limitations and Who Should Be Cautious

• This checklist is general education, not a personalized screening plan. Your provider may recommend more, less, or different testing based on your specific history.
• Symptoms are not a reliable way to diagnose or rule out an STI — testing is required to confirm status either way.
• Testing “windows” vary by infection; a test taken too soon after exposure may not detect a new infection. Ask your provider when retesting is appropriate.
• People with symptoms, a known exposure, or a partner with a confirmed STI should not rely on self-testing alone and should seek prompt clinical evaluation.
• This article does not cover every population or scenario (for example, screening nuances for transgender and gender-diverse patients, or for people living with HIV) — anyone in these situations should ask a provider directly which schedule applies to them.

Frequently Asked Questions

Do I need to know a specific test name before my appointment?

No. Bring your checklist of anatomy, practices, symptoms, pregnancy status, and testing history instead — your provider will select the right tests from that information.

Can I get tested if I don’t have any symptoms?

Yes. Most STIs have no symptoms, and providers commonly recommend testing based on exposure and risk factors rather than waiting for symptoms to appear.

Is a urine test enough to check for all STIs?

No. A urine test typically checks for infections like chlamydia and gonorrhea in the urethra. Other infections and other exposure sites, such as the throat or rectum, may require blood tests or swabs.

How often should I get retested after a positive result and treatment?

Retesting schedules depend on the infection and can include a follow-up test a few months after treatment. A provider can tell you the appropriate timing for your specific diagnosis.
