This page is general health information, not medical advice. It cannot tell you whether you have an infection. A clinician can, and the testing options on this site are a good place to start.

There is no single schedule that fits everyone. How often to get a full panel std test depends on your age, your partners, your body and your health history. The good news is that the main national guidance is clear, and you can turn it into a personal plan in a few steps.

This guide walks you through that process for life in Boston. It uses the CDC STI Treatment Guidelines (2021), later CDC updates and the Massachusetts Legislature for state law.

What a full panel usually includes

"Full panel" is not a medical term with one fixed meaning. Clinics build panels differently. Most cover HIV, syphilis, chlamydia and gonorrhea. Many add hepatitis C. Some add hepatitis B, trichomoniasis or herpes antibody blood tests when a clinician thinks they fit your situation.

The Boston Medical Center STD Clinic says its free routine testing covers HIV, chlamydia, gonorrhea, syphilis and hepatitis C. Ask any clinic exactly what is in its panel before you book. Then you will know what a result does and does not cover.

Materials you need

A rough list of when you last tested and what was tested.
A short, private note about partners since then: how many, and whether any were new.
Your insurance card, if you have one. You can still be seen without it at several Boston clinics.
Any symptoms you have noticed, with dates. Symptoms are a reason to be seen soon, not just on a schedule.
A list of questions for the clinician.

Step 1: Start with the baseline for everyone

The CDC recommends that everyone aged 13 to 64 be tested for HIV at least once as part of routine health care. The CDC also recommends hepatitis C screening at least once for all adults, and during each pregnancy. The USPSTF makes similar recommendations for HIV and hepatitis C.

If you have never had either test, a first full panel is a reasonable place to begin. After that, your schedule depends on the steps below.

Step 2: Match your age and body to the CDC schedule

For chlamydia and gonorrhea, the CDC STI Treatment Guidelines and the USPSTF recommend yearly screening for sexually active women under 25. They also recommend it for older women with risk factors, such as a new partner or a partner with other partners.

For pregnancy, the CDC recommends screening for HIV, syphilis and hepatitis B at the first prenatal visit. A clinician may repeat some tests later in pregnancy, depending on your situation.

The guidelines are written around anatomy and sexual contact, not identity. Transgender and gender diverse people can ask a clinician which sites and tests apply to their body and the kind of sex they have.

Step 3: Adjust for partners and sexual activity

The CDC suggests testing at least once a year if you are sexually active and have new or multiple partners. Gay, bisexual and other men who have sex with men are advised to test for HIV, syphilis, chlamydia and gonorrhea at least yearly. The CDC says testing every 3 to 6 months may be better if you or a partner have several partners, or if a partner has had other partners.

Other reasons a clinician may suggest a shorter interval include:

A new partner, or a partner who has been newly diagnosed with an STI.
A recent STI of your own.
Sharing injection equipment.
Sex while using substances that make safer-sex choices harder.

None of these say anything about your character. They are simply points on the calendar when a test can give useful information.

Step 4: Factor in PrEP and doxy-PEP

If you take HIV PrEP, regular visits usually include STI testing. The CDC's 2024 update on doxycycline post-exposure prophylaxis (doxy-PEP) says clinicians can discuss it with gay, bisexual and other men who have sex with men and transgender women who have had a bacterial STI in the past year. The CDC also advises STI screening every 3 to 6 months for people who use it.

Whether either option fits you is a conversation with a clinician, who is the only one who can prescribe it. Fenway Health lists PrEP, PEP and doxy-PEP among its services. Several other Boston clinics list PrEP.

Step 5: Write down your interval

Put the pieces together in one sentence. For example: "I plan to test every 12 months, and sooner after a new partner." Or: "Every 3 to 6 months, because my clinician and I agreed on that." Set a phone reminder so the date does not slip.

Here is a rough summary of the CDC and USPSTF ideas above. It is a starting point, not a prescription:

Situation	Common CDC-based approach
Never tested for HIV or hepatitis C	At least one test for each
Sexually active woman under 25	Chlamydia and gonorrhea screening every year
New or multiple partners	At least yearly, sooner after a change
Men who have sex with men	At least yearly for HIV, syphilis, chlamydia, gonorrhea; every 3 to 6 months for higher activity
On PrEP or doxy-PEP	Often every 3 to 6 months, per clinician
Pregnant	HIV, syphilis and hepatitis B at the first prenatal visit

Step 6: Pick a Boston place to test

Boston has several options at no cost or on a sliding scale. A few examples, with details that clinics publish themselves:

Boston STD Clinic (Boston Medical Center), 725 Albany St., 9th Floor, Suite 9C. The clinic's page lists free routine testing and help with costs for people without insurance. Appointments are by phone at 617-414-2803. The page does not say whether walk-ins are accepted.
Fenway Health Sexual Health Clinic, 1340 Boylston Street, 4th floor. It lists walk-in hours Tuesday 1 to 7 p.m., Wednesday and Thursday 3 to 7 p.m. and Friday 9 a.m. to 12 p.m. Monday is by appointment. Results take 3 to 5 business days. Its page is aimed at gay, bisexual and other men who have sex with men, transgender and gender diverse people, and their partners. Call 617-267-0159.
X-Clinic at Codman Square Health Center, 637 Washington St., Dorchester. It lists walk-in express visits for people without symptoms or a known exposure, plus a sliding fee. Its pages show different schedules, so call 617-822-8350 first.
Multicultural AIDS Coalition (TrueCare@MAC), 9 Palmer Street, Roxbury. It lists free testing with or without an appointment. Call 617-442-1622.

The Boston Public Health Commission also runs the Mayor's Health Line at 617-534-5050, which offers free, confidential health information and referrals.

Step 7: Know your privacy and consent rights

Under Massachusetts General Laws chapter 112, section 12F, a minor who reasonably believes they are at risk because of sexual activity may consent to care for an STI without a parent. The City of Boston tells people 13 or older they can get a confidential STI test without parental permission.

Chapter 111, section 119 makes venereal disease reports and records non-public, with narrow exceptions such as a court order. Under chapter 111, section 111, cases of reportable infections are reported to local boards of health under health department rules. That is a public health process, not a public announcement.

Step 8: Review results and set the next date

Ask how and when you will receive results. Fenway Health, for example, lists 3 to 5 business days. Before you leave, ask the clinician whether your next test should be in 3, 6 or 12 months, and write it down.

If any test is positive, a clinician can explain next steps. Chlamydia, gonorrhea, syphilis and trichomoniasis are curable with treatment prescribed by a clinician. HIV, herpes and HPV are not curable but are treatable or manageable. Massachusetts also allows expedited partner therapy for chlamydia under M.G.L. chapter 111, section 121B, so a clinician may be able to help partners get treated.

Expected results

A negative result may mean the tests found no sign of the infections they check for. It may not cover every infection, and it may not catch a very recent exposure. The CDC publishes window periods for each test, and a clinician can tell you when a repeat test might be useful.

A positive result is a reason to talk with a clinician about treatment and partners. It is not a judgment, and it is very common. The Boston 25 News report of CDC county data put Suffolk County's 2021 chlamydia rate at 807.8 per 100,000 people and its gonorrhea rate at 298.0 per 100,000. These are county figures, which cover more than the city of Boston.

Tips

Test at the same time each year, such as around a birthday, so the habit sticks.
Bring partners. Testing together is simple and often quicker.
Say plainly what kind of sex you have, so the clinician can choose the right sample sites.
Keep a short record of dates and results in your phone.
If a clinic's hours or walk-in policy are unclear, call first. Several Boston pages differ from each other.

Common mistakes to avoid

Assuming a panel covers everything. Ask which infections are included. Herpes and HPV are not part of every panel.
Waiting for symptoms. Many infections cause none, which is why the CDC recommends routine screening.
Testing too soon after an exposure. A test taken within the window period may be less informative. Ask a clinician about repeat timing.
Treating one test as permanent. A result reflects the day of testing, and new exposures need new tests.
Letting cost stop you. Free and sliding-scale options exist in the city.

The takeaway

For many sexually active adults, a full panel std test about once a year is a sensible starting point under CDC guidance. Some people are advised to test every 3 to 6 months, and some need a different schedule entirely. A Boston clinician can help you set the right interval for you.
