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.

A full panel STD test sounds like it covers everything. In practice, there is no single standard "full panel." The name means different things at different clinics and labs.

This guide shows you how to find out what a full panel STD test includes, what it usually leaves out, and how to ask for the right tests in Boston. It is built around one question: what is actually in the panel you are being offered?

What you need before you start

A list of the tests you were offered, or the name of the panel on the order form.
A rough timeline of any recent exposures, in plain terms (for example, "about three weeks ago"). A clinician uses this to choose tests and timing.
Your insurance card, if you have one. Some Boston clinics also see people without insurance.
A list of any symptoms, even mild ones, and when they started.
Your questions, written down. A short list helps in a short visit.

Step 1: Treat "full panel" as a label, not a promise

Labs and clinics build their own bundles and give them names like "full panel," "complete," or "comprehensive." The CDC STI Treatment Guidelines (2021) do not define a single full panel. They recommend screening based on age, anatomy, sexual practices and risk. So two people can both get a "full panel" and receive different tests.

Ask for the test list by name. If the name of the bundle is all you get, ask for the individual tests.

Step 2: Learn what a panel usually includes

Most panels center on infections that the CDC guidelines recommend screening for in people without symptoms. These commonly include:

Chlamydia and gonorrhea. Usually a urine sample or a swab. The CDC recommends testing at each site of sexual contact, which can include the throat and rectum as well as the genitals.
Syphilis. Usually a blood test.
HIV. Usually a blood test. The CDC recommends that everyone ages 13 to 64 get tested at least once, with more frequent testing for some people.
Hepatitis C. The CDC recommends that all adults 18 and older be screened at least once, and that pregnant people be screened during each pregnancy.

In Boston, the Boston STD Clinic at Boston Medical Center says its free routine testing covers HIV, chlamydia, gonorrhea, syphilis and hepatitis C. That is a useful picture of what a core panel looks like in this city.

Step 3: Learn what a panel often leaves out

This is where a "full panel" can surprise people. Several infections are not routinely included, and for good reason.

Herpes

The CDC guidelines do not recommend routine herpes blood testing for people without symptoms. The blood tests cannot always tell where an infection is, and a positive result can be hard to interpret. If you have a sore or blister, a clinician can swab it directly. That is a different test from a blood panel.

HPV

There is no routine HPV test in a standard STI panel for people who do not have a cervix. For people with a cervix, HPV testing is part of cervical cancer screening, which is a separate visit with its own schedule. The CDC also describes an HPV vaccine. Ask a clinician about it. Planned Parenthood League of Massachusetts and DotHouse Health both list HPV vaccine services in the CDC GetTested directory.

Trichomoniasis and Mycoplasma genitalium

The CDC guidelines do not recommend routine screening for these in most people without symptoms. A clinician can order a test if you have symptoms or a partner has been diagnosed. Both can be treated by a clinician. Trichomoniasis is curable with treatment, as are bacterial STIs.

Hepatitis B

Hepatitis B is sometimes missing from a bundle. The CDC recommends that adults get screened at least once, so ask whether it is included or whether a clinician can add it. Some clinics also offer vaccination.

Less common infections

Tests for things like mpox or bacterial vaginosis are not part of a standard panel. A clinician can tell you whether they are relevant to your situation.

Step 4: Match the panel to your body and your life

The CDC guidelines tailor screening to the person. They do not use one list for everyone. For example:

Sexually active women under 25 are recommended for yearly chlamydia and gonorrhea screening, and older women are screened based on risk.
Gay, bisexual and other men who have sex with men are recommended for at least yearly testing at each site of contact, and some people benefit from more frequent testing.
Transgender and gender diverse people are screened based on the anatomy they have and their sexual practices, not on gender label.
Pregnant people have additional recommended tests, including syphilis, HIV and hepatitis B. The USPSTF also recommends syphilis screening in pregnancy.

Tell the clinician which body parts have been involved in sex. A urine-only panel does not check the throat or rectum. That is one of the most common gaps in a full panel STD test.

Step 5: Ask about timing

Every test has a window period. This is the time after an exposure when a test may not yet detect an infection. For HIV, the CDC says a nucleic acid test can usually detect HIV 10 to 33 days after exposure. An antigen/antibody test done on a lab blood draw can usually detect it 18 to 45 days after exposure. Finger-prick tests may take 18 to 90 days.

For other infections, the CDC does not give one simple window to quote here. Ask the clinician how timing affects the tests on your panel. They may suggest testing now and again later.

Step 6: Choose where to go and confirm the details

Boston has several options. The most useful step is to call and ask what is in the panel. Here are a few, with details from each source:

Boston STD Clinic (Boston Medical Center), 725 Albany St., 9th Floor, Suite 9C. Phone 617-414-2803. The clinic's page lists free routine testing and says it is not confirmed whether walk-ins are accepted, so call first.
Fenway Health Sexual Health Clinic, 1340 Boylston Street, 4th floor. Phone 617-267-0159. The clinic lists walk-in hours on certain days and says 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.
TrueCare@MAC testing (Multicultural AIDS Coalition), 9 Palmer Street, Roxbury. Phone 617-442-1622. The coalition lists testing with or without an appointment.
X-Clinic at Codman Square Health Center, 637 Washington St., Dorchester. Phone 617-822-8350. The clinic lists a sliding fee schedule. Its two pages show different hours, so call to confirm.

For the full local list with costs and hours, see the Boston clinic list. For a wider look at where to go and what it costs, read STD testing in Boston: where to get tested and what it costs. The Boston Public Health Commission also runs the Mayor's Health Line at 617-534-5050, which offers free, confidential, multilingual information and referral.

Step 7: Ask these questions at the visit

Which exact tests are in this panel?
Are throat and rectal swabs included if those sites were involved?
Is hepatitis B or hepatitis C included?
Is herpes testing included, and would it make sense for me?
How does timing since my exposure affect these results?
How and when will I get results, and who will call me if something needs follow-up?
If a result is positive, what happens next?

Tips

Write down the name of every test you receive. Keep it with your records so you know what has been checked next time.
If you have symptoms, say so. A clinician may add tests that a routine panel would not include.
If you have a partner who was diagnosed with an infection, tell the clinician. Massachusetts law (M.G.L. c. 111, s. 121B) lets clinicians prescribe to partners of patients diagnosed with chlamydia under Department of Public Health rules, according to the CDC's summary of the law.
Ask about prevention too. Fenway Health and the Boston STD Clinic both list PrEP and PEP among their services. Fenway also lists doxy-PEP, which the CDC addressed in its 2024 guidance.
Records are private. Massachusetts General Laws c. 111, s. 119 makes venereal disease reports and records non-public, with limited exceptions.

Common mistakes to avoid

Assuming "full" means everything. As covered above, herpes, HPV, trichomoniasis and hepatitis B are often outside a standard bundle.
Testing only one site. A urine sample does not check the throat or rectum.
Testing too soon after an exposure. A test done inside the window period may not detect an infection. Ask whether to repeat it.
Treating one result as a lifetime answer. A result reflects the day of the test and the infections that were checked.
Skipping the results follow-up. Ask how results reach you before you leave.

What results can and cannot tell you

A negative result on a test may suggest that the infection that test looks for was not found in that sample. It does not speak to infections that were not tested, and timing can affect it. A positive result is something a clinician can confirm and explain. Bacterial STIs and trichomoniasis are curable with treatment from a clinician. HIV and herpes are not curable, but they are treatable and manageable. HPV is not curable either, though many infections clear on their own and clinicians can manage related health problems.

For context, the CDC county data reported by Boston 25 News and Stacker in March 2024 put Suffolk County's 2021 chlamydia rate at 807.8 per 100,000 and its gonorrhea rate at 298.0 per 100,000. Suffolk County is larger than the city of Boston, so these are not city-only figures. They show why many people in this area ask about regular testing. The Boston Public Health Commission and the clinics above can tell you what makes sense for you.
