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.

Wanting answers fast is normal. Waiting on STD test results can be stressful, and many people in Pittsburgh ask how long do STD test results take before they book a visit.

The honest answer is that it depends on the test. Some can return a result during your visit. Others go to a lab and take a few days.

This guide walks you through getting tested in Pittsburgh, step by step. It explains which tests can be rapid, which usually cannot, and how to plan your visit around that.

Why a quick plan helps

Testing is a routine part of health care. The CDC STI Treatment Guidelines (2021) recommend regular screening based on age, anatomy and sexual practices, and the U.S. Preventive Services Task Force (USPSTF) also recommends screening for certain groups.

In Allegheny County, the Allegheny County Health Department (ACHD) reported a chlamydia rate of 421.3 per 100,000 people in 2024, with 5,190 cases. It also reported 2,574 gonorrhea cases, a rate of 209.0 per 100,000. These infections are common, and they are treatable with care from a clinician.

Knowing what to expect on timing makes the process easier. It also helps you avoid showing up for a rapid test at a place that only draws blood for a lab.

What you need before you go

You do not need much. Gather these items first.

A photo ID. ACHD says a photo ID is not required to be seen, but it is required to receive results.
Insurance information, if you have it. Some clinics accept insurance or Medicaid. Others offer free or sliding-scale testing. You can usually still be seen without coverage, so ask the clinic.
A working phone number. Clinics use it to share results that are not ready during the visit.
A short list of dates and questions. Note when you last had a possible exposure, any symptoms, and what you want to ask. This helps the clinician choose the right tests.
Time. Walk-in visits are first come, first served, so plan for a wait.

Which tests can give same-day results?

A test is only "same day" if it can be run on the spot. Here is how that usually breaks down.

Tests that are often rapid

Rapid HIV tests. These use a finger stick or an oral swab. Allies for Health + Wellbeing says rapid HIV results are ready in about 20 minutes. Planned Parenthood of Western Pennsylvania and Central Outreach Wellness Center are listed on the CDC GetTested directory as offering rapid HIV testing.
Rapid syphilis tests, where offered. Allies lists rapid syphilis results in about 20 minutes at its testing sites. Not every clinic offers this, so ask when you book.
Rapid hepatitis C tests, where offered. Allies also lists hepatitis C results in about 20 minutes.

Tests that usually take longer

Chlamydia and gonorrhea. These are usually checked with a nucleic acid amplification test (NAAT), which the CDC STI Treatment Guidelines (2021) describe as the recommended approach. The sample is a urine sample or a swab from the throat, rectum or genitals, and it goes to a lab. Clinics commonly quote about one to three days, but turnaround depends on the lab. Ask the clinic what to expect.
Herpes blood tests, hepatitis B and many full panels. These are generally sent to a lab as well. The clinic can tell you the usual timing.

A same-day visit can still be useful if only some of your results come back that day. You can often finish the whole set of tests in one trip.

Step-by-step: getting tested in Pittsburgh

Step 1: Decide which tests you want to ask about

Think about what you want to ask the clinician about. Many people ask about HIV, syphilis, chlamydia and gonorrhea together. Others add hepatitis C or herpes.

You do not have to pick perfectly. A clinician can talk through your sexual health history and suggest tests based on CDC guidance. Tell them about every site of possible exposure, such as genital, oral or anal, because swabs may be taken from different places.

Step 2: Check the timing of your exposure

A test can miss an infection if it is done too soon after an exposure. This early period is called the window period.

For HIV, the CDC says the window period depends on the type of test. It lists roughly 10 to 33 days for a nucleic acid test, 18 to 45 days for a lab antigen/antibody test using a blood draw, and 18 to 90 days for a rapid antigen/antibody test using a finger stick. Antibody tests may take longer, about 23 to 90 days.

For other infections, the clinician can explain when testing is most informative. If your exposure was recent, ask whether a repeat test later would make sense. This is a normal question and clinics hear it often.

If you think you may have been exposed to HIV within the last 72 hours, call a clinic right away and ask about post-exposure prophylaxis (PEP). A clinician decides whether PEP is appropriate. ACHD lists PEP and asks you to call the clinic at 412-578-8081 for urgent guidance.

Step 3: Choose a place that fits your timeline

Walk-in sites are the best fit if you want to be seen quickly. Appointment-only sites can still be fast, but you need to book first. Here are the Pittsburgh-area options, and you can compare more on our local testing list.

Allegheny County Health Department Sexual Health Clinic, Downtown. 425 First Avenue, Fourth Floor (entrance on Cherry Way), Pittsburgh, PA 15219. Phone 412-578-8081. Testing is free. Walk-ins are accepted. ACHD says appointments get priority and walk-ins are first come, first served. Listed hours are Monday, Tuesday, Wednesday and Friday 9:00 am to 3:45 pm, and Thursday 11:30 am to 6:15 pm, with a lunch closure. Hours may vary on holidays. Another ACHD page shows different Wednesday hours, so call to confirm.
Allegheny County Health Department Sexual Health Clinic, McKeesport. 339 Fifth Avenue, McKeesport, PA 15132. Phone 412-578-8081. Testing is free, walk-ins are accepted, and it is open Monday to Friday 9:00 am to 3:45 pm with a lunch closure.
Allies for Health + Wellbeing. 211 North Whitfield Street, Suite 500, Pittsburgh, PA 15206. Phone 412-345-7456. Free walk-in testing is listed at the Allies office on Sundays, 9 to 11:15 am and 1 to 4:15 pm. Allies also lists weekly walk-in sites around the city, including Unity Recovery on Tuesdays, Pittsburgh Action Against Rape on Wednesdays and Bethany Baptist Church on Fridays. Allies posted a notice that a past Sunday session was canceled, so confirm before you go. Clinic visits may require an appointment.
Central Outreach Wellness Center. 127 Anderson Street, Suite 101, Pittsburgh, PA 15212. Phone (412) 322-4151. It is an LGBTQ-focused community health center and offers sliding-scale options. The CDC GetTested directory says no appointment is required, but the center's own page does not say which site does walk-in STI testing, so call first.
Planned Parenthood of Western Pennsylvania, 933 Liberty Ave. Phone (412) 434-8971. The CDC GetTested directory lists rapid HIV testing and sliding-scale fees, and says an appointment is required. Hours are not listed there, so confirm with the organization.
University Family Medicine UPMC, Squirrel Hill. 5608 Wilkin Ave, Suite 100, Pittsburgh, PA 15217. Phone (412) 422-8762. The CDC directory lists an appointment requirement and says insurance and Medicaid are accepted. The cost is not listed, so ask the office.

You can also search the CDC's directory at gettested.cdc.gov by ZIP code to see other nearby sites.

Step 4: Call ahead and ask three questions

A two-minute call can save a trip. Ask these questions:

Do you offer rapid HIV or rapid syphilis tests, and are they available today?
Are walk-ins accepted, and what is the usual wait?
How and when will I get the rest of my results?

Walk-in schedules can change. Calling is the best way to be sure.

Step 5: Go to your visit

Bring your ID and any insurance card. You will usually fill out a short form about your health and sexual history. Clinic staff ask these questions to choose the right tests, not to judge you.

Depending on the tests, you may give a urine sample, a swab, a finger stick or a blood draw. Many of these samples can be self-collected in private.

If you have symptoms such as a sore, discharge or pain, mention them. A clinician can examine you and decide what to test for.

Step 6: Ask how you will get your results

Before you leave, confirm how results will reach you. Options may include a phone call, a patient portal or a return visit. ACHD notes that a photo ID is required to receive results, so keep it handy.

Ask what number the clinic will call from. That way you will recognize it and not miss the call.

Step 7: Plan for what comes next

A clinician will explain your results and next steps. If a test is positive, treatment is prescribed by a clinician. Bacterial infections like chlamydia, gonorrhea and syphilis, and trichomoniasis, are curable with treatment from a clinician. HIV and herpes are not curable, but they are treatable and manageable with care from a clinician.

Pennsylvania's rules on reporting mean that some positive results are shared with public health. According to 28 Pa. Code 27.21a, laboratory-confirmed chlamydia, gonococcal infections, syphilis and HIV are reportable within five work days. This is how health departments track trends and help connect people to care.

How long do STD test results take?

This table gives a general sense of timing. Your clinic's own schedule is what counts, so treat these as typical ranges and not promises.

Test	Common timing	Notes
Rapid HIV test	About 20 minutes where offered	Allies lists about 20 minutes. Window period depends on the test type, per the CDC.
Rapid syphilis test	About 20 minutes where offered	Listed by Allies. Not every site offers it.
Chlamydia and gonorrhea NAAT	Often about one to three days	Sent to a lab. Ask the clinic for its timing.
Lab blood tests (HIV lab test, herpes, hepatitis B)	Varies	Ask the clinic when to expect a call.

Many people also want to know what a result means. A rapid test result is a screening result. A clinician may recommend a follow-up test to confirm it.

What your results may show

Test results are not a guarantee about your health. A negative result suggests the test did not detect an infection at that time. It may not rule out an infection if the exposure was recent and the test was inside the window period.

A positive or reactive result means the test detected something. A clinician will explain whether more testing is needed and what treatment options exist.

Only a clinician can interpret your STD test results in the context of your history. If anything on your report is unclear, ask them to explain it in plain words.

Tips for a smoother visit

Go early in the day for walk-ins. Waits can build as the day goes on. Most listed hours end by mid-afternoon at ACHD, except Thursday.
Check hours the same day. Hours can change around holidays, and different pages may list different times.
Ask about all the sites that matter. If you have had oral or anal sex, a urine test alone may not cover every site. Ask whether throat or rectal swabs are right for you.
Ask about PrEP and prevention. ACHD lists PrEP, PEP and doxy-PEP among its services. A clinician decides whether any of these fit your situation.
Bring a friend if it helps. Some people find a visit easier with support.

Common mistakes to avoid

Testing too soon after an exposure and stopping there. Ask whether a repeat test later makes sense.
Assuming every clinic has rapid tests. Some send everything to a lab. Ask first.
Forgetting ID. You may be seen without it at ACHD, but you will need it to receive results.
Not confirming how results arrive. Missed calls can delay follow-up care.
Waiting because of cost worry. ACHD testing is free, and other sites offer sliding-scale or financial assistance. Allies says it offers financial assistance but does not publish prices, so ask.

Special situations

Teens and minors

Under Pennsylvania law (Act of Feb. 13, 1970, P.L. 19, No. 10), a minor may consent to medical services to determine the presence of or treat venereal disease. The consent of no other person is needed. ACHD says its Sexual Health Clinic sees anyone age 13 and older without parental consent.

Immigration status

ACHD says patients are seen regardless of immigration status.

Testing from home

If you prefer privacy, ACHD lists free at-home test kits for gonorrhea, chlamydia, syphilis and HIV, ordered through lumba.health/achd. One county flyer reportedly limits kits to Allegheny County residents age 16 or older, so check the ACHD page for current eligibility. Mailed kits do not give same-day results, since samples or follow-up take time.

Partners

Pennsylvania law (35 P.S. 603) lets a health care practitioner prescribe or furnish antibiotics for STIs without examining the partner, as described by the CDC's page on expedited partner therapy. Ask your clinician whether this applies to you.

Pregnancy

Under 28 Pa. Code 27.89, a physician examining a pregnant person is directed to offer a syphilis test at the first exam. The Pennsylvania Department of Health also recommends testing later in pregnancy and at delivery. Talk with your prenatal provider about timing.

Next step

If you want a quick answer, call a walk-in site such as the ACHD Sexual Health Clinic at 412-578-8081 or Allies at 412-345-7456. Ask about rapid tests and the day's schedule. If you prefer to compare options, use the CDC GetTested directory.

Getting tested is a routine step in taking care of your health. Whatever your result, there are people in Pittsburgh ready to help with the next step.
