Why testing matters in Clark County

Many STIs cause no symptoms, especially early on. The CDC's STI Treatment Guidelines (2021) are built around this fact. They recommend screening based on age, sex, sexual practices and other factors, whether or not someone feels unwell. Testing is how you find out what is happening in your body, and it works the same way for people of every gender and orientation.

Las Vegas is part of Clark County, and the Southern Nevada Health District covers communicable disease there. The district says it serves more than 2.3 million residents. The Nevada Office of State Epidemiology published these figures for Clark County in its Nevada 2023 STD Fast Facts:

Chlamydia: 12,563 cases, or 525.2 per 100,000 people.
Gonorrhea: 5,768 cases, or 241.1 per 100,000 people.
Primary and secondary syphilis: 554 cases, or 23.2 per 100,000 people.

For HIV, the Nevada Division of Public and Behavioral Health's 2024 HIV Fast Facts reports 552 new diagnoses in Clark County, or 22.6 per 100,000 people.

These numbers describe diagnosed cases, not individual risk. They show that testing and treatment are a normal, common part of community health here. The same state reports also note that most of these infections can be treated or managed once they are found.

Provisional 2025 counts from the Southern Nevada Health District are lower than 2024 for several infections. Provisional data can change, and a drop in reported cases does not necessarily mean less transmission. Preliminary 2025 HIV data from the state carry the same caution.

Where to get tested in Las Vegas

People looking for an STD clinic in Las Vegas usually find a few kinds of providers. The sections below cover what the Southern Nevada Health District, community health centers and others publish about their services. You can also see a short list of local options on our local testing list.

Southern Nevada Health District Sexual Health Clinic

The health district runs the main public STI clinic in the county. It has two Las Vegas locations, both reached at (702) 759-1700.

Main facility (Decatur): 280 S. Decatur Blvd., Las Vegas, NV 89107.
Fremont Public Health Center: 2830 E. Fremont St., Las Vegas, NV 89104.

The clinic page says walk-ins for STI testing and treatment are available until capacity is reached. Listed services include STD testing, HIV testing, rapid HIV testing, treatment, and PrEP and PEP by appointment. The Decatur site also lists doxy-PEP among its services.

Hours listed on the sexual health clinic page:

Decatur: Monday, Wednesday and Thursday 7:00 AM to 6:00 PM; Tuesday 9:00 AM to 6:00 PM.
Fremont: Tuesday 9:00 AM to 6:00 PM; Wednesday, Thursday and Friday 7:00 AM to 6:00 PM. The page asks people to arrive by 5:30 PM to allow time for processing.

The district's own pages do not list identical hours for these sites. Call (702) 759-1700 or check the district's sexual health page before you travel.

Free Express Testing

The health district offers free Express Testing, a walk-in service for people who do not have symptoms. It lists these hours:

Decatur: Monday to Thursday, 7:30 AM to 12 PM and 1 PM to 3:30 PM.
Fremont: Fridays, 7:30 AM to 4 PM.

The district also offers Express Testing at its Henderson (Tuesdays) and Mesquite (fourth Monday) public health centers, which are outside Las Vegas city limits. For a fuller look at free options, see free and sliding-scale STD testing in Las Vegas.

The Center: Arlene Cooper Community Health Center

The Arlene Cooper Community Health Center is run by The LGBTQ Community Center of Southern Nevada. It is at 401 S. Maryland Parkway, Las Vegas, NV 89101. Appointments are at 702-802-5432, and the main Center line is (702) 733-9800.

The health center page describes fast, free HIV testing and STI screening at a low cost, with certain insurance billed. It also says STI treatment is provided on site. Appointments are highly encouraged, though walk-in services are available for a limited number of patients daily.

The listed hours are Monday to Friday 8:00 AM to 6:00 PM and Saturday 7:30 AM to 4:00 PM, with Sunday closed. The site footer shows different hours, so confirm by phone. Care is open to the whole community, and the setting is LGBTQ+ led.

Nevada Health Centers

Nevada Health Centers is a federally qualified health center network. It lists STD testing among its reproductive health services at two Las Vegas sites:

Martin Luther King Family Health Center: 1799 Mount Mariah Dr., Las Vegas, NV 89106. Phone 702.383.1961 or 800.787.2568.
Nellis Family Medical Center: 691 N. Nellis Blvd., Las Vegas, NV 89110. Phone 702.563.4662 or 800.787.2568.

The organization offers a sliding-fee discount program based on family size and income. Its HIV care and prevention page lists HIV testing, PrEP and PEP across the organization. That page does not name specific sites, and walk-in availability is not stated, so call ahead.

UNLV Student Health Center

The UNLV Student Health Center, at 4505 S. Maryland Pkwy., lists testing for sexually transmitted infections, including HIV. It serves UNLV students rather than the general public. The phone number is 702-895-3370, and the page does not publish prices.

Planned Parenthood, urgent care and primary care

Planned Parenthood health centers, urgent care clinics and primary care offices also offer STI testing in many places. We do not list their addresses, hours or prices here, because we have not confirmed them from a published source. Call the provider and ask three things: which tests they offer, what the visit costs with and without insurance, and whether you need an appointment. Our guide to STD clinics in Las Vegas compares the main types of provider.

The CDC's GetTested locator lets you enter a ZIP code to find testing sites close to where you live, work or study.

At-home options

Two programs are described in published sources:

Collect2Protect (Southern Nevada Health District): at-home HIV self-test kits and mail-in self-collect kits for gonorrhea and chlamydia. It is open to Nevada residents. The district says no insurance or Medicaid is accepted, and results can be ready within 7 to 10 business days after the laboratory receives the specimens. A 2020 district news release described the HIV kits as free and the gonorrhea and chlamydia kits as fee-based. The current program page does not state prices, so ask the district for current costs.
Together TakeMeHome: free mailed HIV self-tests for anyone 17 and older in the U.S., with two available every 90 days, according to its FAQ. It is a collaboration that includes Emory University, the CDC and NASTAD.

A self-test checks only for the infections it is designed to detect. Any result you are unsure about should be followed up with a clinician. Our comparison of at-home tests and clinic testing in Las Vegas explains the tradeoffs.

What STD testing costs

Published prices for STD testing in Las Vegas are limited. Here is what each source says.

Provider	What the provider publishes
Southern Nevada Health District Express Testing	Free for people without symptoms.
Southern Nevada Health District Sexual Health Clinic	Charges are based on your income and the number of people in your household. You will not be turned away on the day of your visit because you cannot pay. Bring proof of income and a photo ID.
The Center (Arlene Cooper Community Health Center)	HIV testing is free. STI screening is low cost. Certain insurance is billed. No dollar amounts are listed.
Nevada Health Centers	Sliding-fee discount program based on family size and income. No dollar amounts are listed.
Collect2Protect mail-in kits	HIV kits were described as free in 2020. Gonorrhea and chlamydia kits have a fee, and the amount is not stated. No insurance or Medicaid accepted.
Together TakeMeHome	Free HIV self-tests for ages 17 and older.
UNLV Student Health Center	The page does not list a price. Contact the center.

No dollar figures appear in these sources, so this guide does not give any. When you call, ask what the visit costs for the tests you want. Ask whether there are separate charges for the visit and for lab work. If you have insurance, ask whether a bill might go to the policyholder. For more on paying with little or no coverage, see low-cost STD testing in Las Vegas without insurance.

Saving money without skipping care

Ask whether free Express Testing fits your situation. It is designed for people who have no symptoms.
If you have symptoms, a sliding-scale visit lets a clinician examine you and choose tests. Fees are based on income and household size.
Bring photo ID and proof of income if you plan to use a sliding-scale program.
Ask the clinic what it can tell you about costs for treatment as well as testing, since both may be part of the same visit.

What to expect at a visit

A first visit can feel unfamiliar. It is usually quick and routine for the staff. Our step-by-step guide to what happens at an STD test goes deeper. This is the general shape of a visit.

Before you go

Check the clinic's current hours, especially for Express Testing, which has narrower hours than the general clinic.
Bring photo ID and, for sliding-scale pricing, proof of income.
Think about the dates of recent sexual contact. A clinician may ask about them to choose the right tests.
Write down any symptoms and any medicines you take.
Plan for time. Walk-in services run until capacity is reached, so arriving early helps.

The conversation

A staff member will ask about your health history, any symptoms and your sexual practices. The questions help them decide which tests make sense. The CDC's STI Treatment Guidelines (2021) encourage clinicians to ask these questions in a respectful, nonjudgmental way. You can ask them to explain why a question matters.

Collecting samples

Depending on the tests, samples may include:

A urine sample.
A swab from the throat, genitals or rectum. Some of these may be self-collected.
A blood draw or fingerstick for HIV, syphilis or hepatitis tests.

The sites tested should match the kinds of sexual contact you have had. A urine test or a swab at one site does not check the other sites. Tell the clinician about all types of contact so they can pick the right ones.

Results and follow-up

Rapid HIV tests may give a result during the visit. Other results arrive later by phone, portal or a follow-up visit. Ask how and when you will hear, and which phone number the clinic will use. If a result needs treatment, the clinic can explain next steps. For more on speed, see same-day STD testing in Las Vegas.

What is tested, and what to ask for

There is no single test that checks for every infection. Which tests make sense depends on your age, your body, your partners, your symptoms and your recent exposures. A clinician can help you choose. The following reflects the CDC's STI Treatment Guidelines (2021) and USPSTF guidance.

Common screening recommendations

HIV: The CDC recommends that everyone ages 13 to 64 be tested for HIV at least once, with more frequent testing for people with ongoing chances of exposure. The USPSTF recommends screening for adolescents and adults ages 15 to 65.
Chlamydia and gonorrhea: The CDC recommends yearly screening for sexually active women under 25, and for older women with risk factors. It also recommends at least yearly screening for gay, bisexual and other men who have sex with men, at each site of sexual contact.
Syphilis: The CDC recommends at least yearly screening for men who have sex with men, and for people with HIV who are sexually active. Clinicians may test others depending on risk.
Hepatitis B and C, trichomoniasis, herpes and HPV: Testing depends on your situation. HPV and herpes are not routinely screened for in people without symptoms, so ask a clinician what applies to you.

Questions worth asking

Which infections will this visit test for, and which will it not?
Which body sites will be tested?
Is there a test I should consider given my recent exposure or symptoms?
When should I test again?
Can I ask about PrEP, PEP or doxy-PEP if they could apply to me?

Window periods

A window period is the time between exposure and the point a test can reliably 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 lab test on blood from a vein can usually detect it 18 to 45 days after exposure.
An antigen/antibody fingerstick test can take 18 to 90 days.
Antibody tests, including most self-tests, can take 23 to 90 days.

Window periods differ for other infections, and the CDC and your clinician are the right source for them. If you tested soon after an exposure, ask whether you should test again later. For HIV-specific options, see free and rapid HIV testing in Las Vegas.

If you have symptoms

Unusual discharge, pain, sores, itching, rash or burning when urinating can have many causes, including infections that are not sexually transmitted. A clinician can examine you and choose tests. A sliding-scale visit is usually the better fit than Express Testing, which is designed for people without symptoms.

Privacy, consent and reporting in Nevada

Many people want to know who will see their results. Our guide to anonymous and confidential STD testing in Las Vegas covers this in more depth. Several points come from Nevada law.

Minors can consent

Under NRS 129.060, a minor may give express consent to examination and treatment for any sexually transmitted disease, and to STD prevention services. The statute names no minimum age. This includes PrEP provided by a pharmacist under NRS 639.28085. If you are under 18, call the clinic and ask how it handles billing and communication. Some insurance statements can reach a policyholder.

Reporting to the health district

Under Nevada Administrative Code chapter 441A, certain infections are reportable communicable diseases. These include chlamydia of the genital tract, gonococcal infection, HIV and syphilis. Health care providers must report cases or suspected cases to the local health authority (NAC 441A.230). This is a public health reporting step, and it is how the health district tracks disease in the community. Ask your clinic how your information is handled.

Telling partners

Expedited partner therapy is permissible in Nevada, according to the CDC's legal status page for Nevada, updated August 13, 2024. In this approach, a clinician may provide treatment for a patient's partner without examining that partner. Whether it is offered is a clinical decision, so ask your clinician whether it applies to you.

HIV and Nevada law

The sources reviewed for this guide found no HIV-specific criminal statute in the current Nevada Revised Statutes. Exposure to any communicable disease is handled under NRS 441A.180, which includes defenses for a partner's informed consent and for using means to prevent transmission. This is general information and not legal advice. If you have a legal concern, contact an attorney or an HIV legal service.

Pregnancy and syphilis testing

Under NRS 442.010, Nevada requires a syphilis test at the first prenatal visit and again in the third trimester (the 27th to 36th week). Testing at delivery is also required in some situations, such as no prenatal care or a stillbirth after 20 weeks. If you are pregnant or planning a pregnancy, tell your prenatal provider about any past or possible infections.

After your results: treatment, partners and prevention

Treatment is prescribed by a clinician

Chlamydia, gonorrhea, syphilis and trichomoniasis are curable with treatment from a clinician. HIV, herpes and HPV are not curable, but they are treatable or manageable. For HIV, the CDC says treatment can lead to an undetectable viral load, which means the virus cannot be passed to partners during sex. Only a clinician can decide which treatment suits you, and it should be taken as prescribed. Never share or save medicine from a previous visit. The Southern Nevada Health District Sexual Health Clinic and The Center both list treatment among their services.

Retesting and partners

The CDC's STI Treatment Guidelines (2021) recommend retesting after treatment for certain infections. Clinicians may also advise partners to be tested or treated. Ask your clinician when to come back and what to do about recent partners.

Prevention tools a clinician can discuss

PrEP is medicine that lowers the chance of getting HIV. The Southern Nevada Health District schedules PrEP and PEP by appointment at (702) 759-1700. The Center offers PrEP navigation, in person and online, with low and no-cost options. Nevada Health Centers lists a PrEP Navigator at 702-563-4618. Nevada law also lets qualifying pharmacists prescribe PrEP under a Board of Pharmacy protocol (NRS 639.28085).
PEP is medicine started after a possible HIV exposure. It works best when started as soon as possible, so call a clinic quickly if you think you may have been exposed.
Doxy-PEP was addressed in CDC guidance in 2024. The CDC advises that a clinician may offer it to some gay, bisexual and other men who have sex with men, and some transgender women, who have had a bacterial STI in the past year. The Southern Nevada Community Health Center lists it among its services. A clinician decides whether it fits your situation.
Condoms and dental dams lower the chance of passing many infections. Vaccines are available for hepatitis A, hepatitis B and HPV. Ask a clinician which are right for you.

Choosing your next step

For no symptoms and no cost, consider health district Express Testing.
For symptoms or a full visit with treatment, consider a sliding-scale clinic. Options include the health district, The Center and Nevada Health Centers.
For HIV only and privacy at home, consider a mailed self-test.
For other situations, use gettested.cdc.gov to find more providers.

Whatever route you choose, going is a step in taking care of yourself and the people you are close to. Clinic staff handle these visits every day.
