Getting an STD test is straightforward: you visit a clinic, doctor’s office, or health department, give a sample (urine, blood, or swab depending on the infection), and typically get results within 5 to 10 days. You can also now test for several infections entirely at home with FDA-authorized kits. The process is private, usually quick, and often low-cost or free.
Where to Get Tested
Most people can get STD testing through a provider they already see. Primary care doctors, OB-GYNs, family medicine offices, and community health centers all offer testing. If you don’t have a regular doctor, dedicated sexual health clinics (sometimes called STD clinics) and family planning clinics like Planned Parenthood are widely available and designed specifically for this.
Urgent care centers and some school-based health centers also provide testing. Public health departments in most counties run sexual health clinics with sliding-scale fees, meaning you pay based on what you can afford. Some waive the fee entirely if you can’t pay.
What Happens During the Test
There’s no single “STD test.” Different infections require different samples, so what happens depends on what you’re being tested for. In most cases, you’ll provide one or more of the following:
- Urine sample: Used to test for chlamydia, gonorrhea, and trichomoniasis. You pee in a cup. That’s it.
- Blood draw: Used for HIV, syphilis, hepatitis B, and sometimes herpes. A small needle draws blood from your arm, the same as any routine blood test.
- Swab: Used for HPV, chlamydia, gonorrhea, and herpes. A provider takes a sample from the site of potential infection, which could be the vagina, cervix, penis, urethra, rectum, or throat depending on your sexual history.
If you go in for a full STD panel, you’ll likely do a combination: a urine sample plus a blood draw, and possibly a swab. The whole visit is usually quick. Many clinics also do a brief risk assessment, asking about your sexual history and partners so they can decide which tests to order. Be honest during this conversation, because testing the wrong sites means infections can be missed entirely.
At-Home Testing Options
If you’d rather skip the clinic visit, at-home options have expanded significantly. The FDA has authorized home collection kits for HIV, chlamydia, gonorrhea, syphilis, and hepatitis C. With most of these, you collect a sample at home and mail it to a lab for processing.
In 2025, the FDA authorized the first test that can be performed and read entirely at home without mailing anything. The Visby Medical Women’s Sexual Health Test checks for chlamydia, gonorrhea, and trichomoniasis using a vaginal swab, with no prescription needed. In clinical studies, it correctly identified over 97% of positive samples and over 98% of negative samples across all three infections.
Some county health programs also ship free home test kits. For example, programs in multiple states offer free chlamydia and gonorrhea kits for people under 25, and free multi-infection kits (HIV, chlamydia, gonorrhea, syphilis, hepatitis C) for anyone who hasn’t been tested in the past year.
How Long Before You Get Results
Standard lab-processed tests typically return results in 5 to 10 days. Some clinics offer rapid tests for HIV and syphilis that give results in 20 to 30 minutes during the same visit. The fully at-home Visby test delivers results in about 30 minutes as well.
Results are usually shared through a patient portal, phone call, or secure message. If something comes back positive, the clinic will contact you to discuss treatment, which for bacterial infections like chlamydia and gonorrhea is a course of antibiotics.
Timing Matters: Window Periods
Testing too soon after exposure can produce a false negative. Each infection has a “window period,” the time it takes for the infection to become detectable. If you test before the window closes, you could be infected but get a clean result.
- Chlamydia: Detectable in most cases after 1 week. Waiting 2 weeks catches nearly all infections.
- Gonorrhea: Similar to chlamydia, roughly 1 to 2 weeks.
- Syphilis (blood test): Detectable in most cases after 1 month. Waiting 3 months catches nearly all.
- HIV (blood test, antigen/antibody method): Detectable in most cases after 2 weeks. Waiting 6 weeks catches nearly all.
- HIV (oral swab): Detectable in most cases after 1 month. Waiting 3 months catches nearly all.
If you had a specific exposure you’re worried about, the practical approach is to test at the earliest useful window and then retest at the longer interval to be sure. For a full panel covering everything, testing at 2 weeks and again at 3 months covers the range.
Who Should Get Tested and How Often
The CDC recommends annual chlamydia and gonorrhea screening for all sexually active women under 25. Men who have sex with men should also be screened for chlamydia, gonorrhea, and syphilis at least once a year, with testing at all relevant body sites (throat, rectum, urine) based on sexual activity. HIV screening should be offered to all adolescents and adults at least once, with repeat testing based on risk.
Pregnant women are routinely screened for syphilis, HIV, and hepatitis B. Outside of these groups, routine screening for infections like herpes, trichomoniasis, and hepatitis in people without symptoms isn’t standard practice, though your provider can order these tests if there’s a reason.
Anyone with a new sexual partner, multiple partners, or a partner who has tested positive should get tested regardless of age or gender.
Cost and Insurance
Most insurance plans cover STD screening, particularly the routine tests recommended by the CDC. Under the Affordable Care Act, preventive screenings are generally covered with no copay.
Without insurance, costs vary. Public sexual health clinics are the most affordable option. As a reference point, San Diego County’s sexual health clinics charge a flat $40 per visit covering the risk assessment, lab tests, any needed treatment, and follow-up visits within 30 days. HIV-only testing is free. And for anyone who can’t afford the fee, it’s waived.
Similar sliding-scale clinics exist in most cities and counties. Planned Parenthood locations also offer testing on a sliding fee scale. At-home test kits purchased directly range from roughly $30 to $150 depending on how many infections are included, though the free programs mentioned earlier eliminate that cost for people who qualify.
Privacy and Confidentiality
STD testing is confidential. Your results are part of your medical record and protected by the same privacy laws as any other health information. If you’re on a parent’s insurance and concerned about an explanation of benefits being mailed home, visiting a public health clinic that doesn’t bill insurance avoids that issue entirely.
Some testing sites, particularly for HIV, offer anonymous testing where your name isn’t attached to the test at all. Instead, you’re identified by a code. This means even the clinic doesn’t have a record linking your name to the result. If anonymity matters to you, call ahead and ask whether the site offers anonymous versus confidential testing.
Certain positive results (HIV, syphilis, gonorrhea, chlamydia) are reported to the local public health department by law. This reporting uses your name in confidential testing or your code in anonymous testing. Public health staff may reach out to help notify partners, but they never reveal your identity to those partners.
