You can get same-day STD testing at several types of facilities: urgent care clinics, Planned Parenthood health centers, local public health departments, and some retail clinics or private labs. Most don’t require an appointment, though walk-in availability varies by location and time of day. The bigger question is whether you need same-day testing or same-day results, because those are two different things.
Same-Day Testing vs. Same-Day Results
Most clinics advertising “same-day STD testing” mean you can walk in and get tested that day. That doesn’t always mean you’ll leave with results in hand. The distinction matters.
Rapid tests for HIV and syphilis can deliver results in about 15 to 30 minutes while you wait. These are point-of-care tests done with a finger prick or oral swab, and they’re widely available at sexual health clinics. For HIV specifically, most rapid tests have sensitivity above 99%, meaning they’re highly accurate at detecting infection. However, rapid tests can be slightly less reliable during the early phase of infection, before your body has produced enough antibodies to detect.
Testing for chlamydia and gonorrhea is a different story. The standard method uses a urine sample or swab sent to a lab for nucleic acid testing, which is the most accurate approach. Lab processing typically takes one to three days, sometimes up to five. Some clinics now offer rapid versions of these tests, but they aren’t available everywhere. If knowing your chlamydia or gonorrhea status the same day is critical, call ahead and ask specifically whether the facility offers rapid results or lab-based results.
Planned Parenthood
Planned Parenthood health centers test for the full range of common STDs and welcome walk-ins during regular hours. If you show up without an appointment, they’ll make every effort to fit you in the same day on a first-come, first-served basis. If they can’t see you, they’ll schedule you for the first available slot. Pricing is on a sliding scale based on income, and many services are covered by insurance or Medicaid. You can find your nearest center on their website and check hours before heading over.
Local Health Departments
City and county health departments often run dedicated sexual health clinics with low-cost or free testing. Many now offer what’s called “Express STI Services” for people who don’t have symptoms and haven’t been notified of exposure. These express visits are streamlined: you provide a urine or blood sample without needing a full clinical exam, covering chlamydia, gonorrhea, HIV, and syphilis. The whole visit can be significantly shorter than a traditional appointment. Call your local health department to ask whether they offer express services and what their walk-in hours look like.
Urgent Care Clinics
Most urgent care centers can order STD panels during a standard visit. The advantage is convenience: they’re widely available, often open evenings and weekends, and generally accept walk-ins. The downside is that urgent care facilities typically send samples to an outside lab, so you’re looking at a few days for results on most infections. Some locations stock rapid HIV tests, but this varies. If speed of results matters, confirm before you go. Expect a copay or visit fee ranging from $100 to $200 without insurance, plus lab charges.
Commercial Labs and Online Ordering
Companies like Quest Diagnostics and Labcorp operate thousands of draw sites across the country. Several online services let you order your own STD panel, then walk into a nearby lab location for sample collection without a doctor’s visit. You typically choose a test package online, pay upfront (usually $50 to $200 depending on the panel), and receive a lab order you can use the same day. Results come back electronically in one to three days. This route offers privacy and convenience, since you skip the clinic visit entirely, but you won’t get rapid results or in-person guidance.
What to Know Before You Go
If your test involves a urine sample, which is standard for chlamydia and gonorrhea screening, try not to urinate for two to three hours beforehand. A full bladder gives the sample enough concentration for accurate results. This is easy to forget, especially if you’re rushing to a walk-in appointment, so plan accordingly.
Bring a form of ID and your insurance card if you have one. If you’re concerned about privacy, many public health clinics and online lab services offer confidential or anonymous testing. At health department clinics, you can often get tested without insurance information at all.
Keep in mind that every STD has a window period: the gap between exposure and when a test can reliably detect infection. For chlamydia and gonorrhea, that window is roughly one to two weeks. For HIV, rapid antibody tests are most reliable about three weeks after exposure, though combination tests that detect both antibodies and viral proteins can pick up infection sooner. Syphilis tests generally become accurate within three to six weeks. If you test too early after a potential exposure, a negative result may not be definitive, and retesting after the window period closes gives you a more reliable answer.
Getting Treated the Same Day
If your rapid test comes back positive for HIV or syphilis, or if you have visible symptoms of an infection like herpes or gonorrhea, many clinics can start treatment during the same visit. For chlamydia and gonorrhea, treatment is straightforward with antibiotics, and some clinics will treat presumptively if your symptoms and risk factors strongly suggest infection, even before lab results are back.
Some facilities also offer something called expedited partner therapy. If you test positive for chlamydia or gonorrhea, the clinic can provide a prescription or medication for your sexual partner without requiring them to come in for their own exam first. The CDC considers this a useful option for managing partner treatment, particularly for male partners of women diagnosed with chlamydia or gonorrhea. Not every state allows it, so ask your provider whether it’s available where you are.
