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.

Waiting for results is often the hardest part of getting tested. Knowing the usual timeline can make the wait easier to plan around.

This guide walks you through how to find out your STD test results time before, during and after a visit in Boston. It covers what changes the timeline, what the CDC says about HIV test types, and what to ask each clinic.

One honest note up front: most Boston clinics do not publish a result time for every infection. Where a time is not published, this guide says so and tells you who to ask.

What you need before you start

A phone number or patient portal login where you are comfortable receiving results.
A list of the infections you want to ask about (for example HIV, chlamydia, gonorrhea, syphilis, hepatitis C).
The approximate date of any recent exposure, if there was one, so a clinician can talk through timing.
Your insurance card, if you have one. Some clinics bill insurance and some do not.
Two or three questions written down (see Step 2).

Why results do not all arrive at the same speed

Two things set the timeline: how a test is run, and where it is run.

Some tests give a read on the spot. The CDC describes rapid HIV tests as ones that can return a result in roughly 30 minutes or less. Other tests are sent to a laboratory, and the result comes back after the lab processes it.

Tests for chlamydia, gonorrhea, syphilis and hepatitis C are typically run on a urine, swab or blood sample, depending on the infection and the body site. A clinician decides which sample fits your situation.

Step 1: Match the infection to the test type

Start by knowing which kind of test you are likely to get. This is the biggest factor in how long you wait.

HIV

The CDC describes three kinds of HIV tests. Each can detect HIV at a different point after exposure, which is called the window period.

Nucleic acid tests (NAT) can usually detect HIV 10 to 33 days after exposure, according to the CDC.
Antigen/antibody tests done on blood from a vein can usually detect HIV 18 to 45 days after exposure, according to the CDC.
Antigen/antibody tests done on a fingerstick can usually detect HIV 18 to 90 days after exposure, according to the CDC.
Antibody tests can usually detect HIV 23 to 90 days after exposure, according to the CDC.

Testing too soon after an exposure can lead to a result that does not reflect what is happening yet. A clinician can tell you whether a repeat test makes sense for you.

Chlamydia, gonorrhea and syphilis

These are bacterial infections, and the CDC STI Treatment Guidelines (2021) describe them as curable with treatment from a clinician. Samples are generally processed by a lab. The clinics in Boston's published listings do not give a standard turnaround for each one, so ask at the visit.

Hepatitis C

Hepatitis C testing is done with a blood sample. Several Boston clinics list it as a service. Ask whether the result comes from the same sample as your HIV test and how long it usually takes.

Herpes and HPV

The CDC STI Treatment Guidelines (2021) do not recommend routine screening for herpes in people without symptoms. HPV testing is handled differently from the other tests above. If either is a concern, a clinician can explain which test, if any, fits your situation and when you would hear back.

Step 2: Ask the clinic these timing questions

Because published result times vary, a short phone call saves guessing. Ask:

Which of my tests give a result during the visit, and which go to a lab?
About how many business days does the lab result take?
How will I be told: phone call, portal message, or in person?
What happens if a result is not what I expected? Who contacts me and how fast?
Is there a cost for the visit, the lab, or a repeat test?

The Boston Public Health Commission runs the Mayor's Health Line at 617-534-5050. The City of Boston describes it as free, confidential, multilingual health information and referral. It is a good place to start if you are unsure where to call.

Step 3: Know what Boston clinics publish about timing

Here is what the clinics' own pages say, and what they leave out.

Fenway Health Sexual Health Clinic says results take 3 to 5 business days. Its page says it bills insurance if you have it, bills Quest Labs separately, and that uninsured patients can be seen free through grant funding. Walk-in hours are listed on the Fenway Health page, and check-in closes 30 minutes before the end time. Call 617-267-0159 to confirm.
Boston STD Clinic at Boston Medical Center lists free routine testing for HIV, chlamydia, gonorrhea, syphilis and hepatitis C. Its page does not list a result time. Call 617-414-2803 and ask. Appointments are made by phone or MyChart, and the page does not say whether walk-ins are accepted.
X-Clinic at Codman Square Health Center lists rapid HIV testing and walk-in express visits for people with no symptoms and no known exposure. Its pages do not list a result time for other tests, and its two pages list different hours. Call 617-822-8350 to confirm.
TrueCare@MAC (Multicultural AIDS Coalition) lists free STD, HIV and hepatitis C testing, with or without an appointment. Its page does not list a result time. Call 617-442-1622.
Planned Parenthood League of Massachusetts and DotHouse Health both list rapid HIV testing in the CDC GetTested directory. Neither listing gives result times or hours. Call Planned Parenthood at 617-295-7235 or DotHouse at 617-288-3230.

For addresses and hours in one place, see the local testing list. For costs and how to choose a site, the guide to where to get tested in Boston and what it costs covers it in more depth.

Step 4: Plan the wait

Once you know the timeline, decide how you will spend those days.

Write down the date you were tested and the date the clinic gave you for results.
Confirm the phone number the clinic has on file is the one you want used. If you share a phone or home with others, say so and ask for a different contact method.
If you were told to expect a call and none comes by the stated date, call the clinic yourself.
If a clinician prescribed treatment, take it exactly as directed by that clinician and ask them any questions about partners or follow-up testing.

Massachusetts law helps with privacy here. The Massachusetts Legislature, in M.G.L. c. 111, s. 119, makes venereal disease reports and records non-public, with disclosure only on a judicial order or to officials whose duties entitle them. Ask the clinic about its own privacy practices too.

Step 5: Read your results with a clinician

A result is one piece of information. It does not replace a conversation with a clinician, who can explain what a test can and cannot show and whether another test is worth doing.

The CDC notes that a test done before the end of its window period may not show an infection yet. If your exposure was recent, ask whether and when to test again.

Tips for a smoother wait

Ask for the result time in business days, since weekends and holidays can add to the wait.
If you want a faster HIV read, ask whether the clinic offers rapid testing and which type it is, because the window period depends on the test type.
Choose a clinic that fits your schedule. Fenway Health lists fixed walk-in blocks, and other sites list different days and evenings.
If you are under 18, Massachusetts law (M.G.L. c. 112, s. 12F) lets a minor who reasonably believes they are at risk consent to STI care without a parent. The City of Boston tells people 13 or older they can get a confidential STI test without parental permission.

Common mistakes to avoid

Assuming every test is a same-day test. Rapid tests are mainly an HIV option. Many other tests go to a lab.
Testing for HIV once and treating the result as final for any exposure. The CDC window periods mean timing matters.
Relying on a hours page without calling. Some Boston listings are incomplete or differ between pages, so confirm by phone.
Not asking how results are delivered. This is the most common reason people feel left waiting.
Taking silence as a result. No call does not by itself tell you anything. Contact the clinic.

What to expect

Many people find that a rapid HIV test returns a read within about half an hour at sites that offer one, according to the CDC. Lab-processed tests at Fenway Health are listed as returning in 3 to 5 business days. For other clinics and infections, the clinic's own staff are the best source for the timeline.

Results can vary with the lab, the sample, and the day of the week. Your clinician can tell you what a particular result means and what, if anything, comes next.
