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.

Getting an HIV test in Tucson is a short, routine health step. Several local clinics offer HIV testing at no cost or on a sliding fee scale, and at least one uses a rapid test with results in about 20 minutes.

This guide walks you through the process from start to finish. It covers what to gather, how to choose a test, who to call, what to expect in the room and what your result can and cannot tell you.

The CDC recommends that everyone ages 13 to 64 get tested for HIV at least once as part of routine health care. The U.S. Preventive Services Task Force (USPSTF) recommends screening for people ages 15 to 65. Testing is also recommended more often for people with ongoing chances of exposure. A clinician can help you decide how often fits your life.

What you need before you go

You do not need much. A little preparation makes the visit smoother.

A phone. Many Tucson clinics ask you to call first, and some give results by phone or follow-up call.
A rough date. Write down the date of any recent possible exposure. This helps the clinician pick a test and explain timing.
Questions. Jot down anything you want to ask, such as cost, privacy or what happens after a reactive result.
Insurance information, if you have it. Some clinics accept insurance or Medicaid. Many do not require it.
A way to be reached. Ask each clinic how they contact people with results and follow-up needs.
About an hour. A rapid test itself is quick, but check-in, a short conversation and counseling add time.

Ask the clinic when you call whether you need to bring photo identification or any paperwork. The health department and clinics set their own rules, and the rules can change.

Step-by-step: how to get an HIV test in Tucson

Step 1: Decide what you want to find out

Start with a simple question: is this routine testing, or is there a specific recent exposure you are thinking about? Both are good reasons to test.

Routine testing fits most people at least once. The CDC also recommends testing at least once a year for people with certain ongoing chances of exposure, such as new or multiple partners. The CDC's recommendations apply to every gender and orientation.

If your possible exposure was in the last few days, mention that when you call. The CDC says post-exposure prophylaxis (PEP), a medicine a clinician prescribes, works best when started as soon as possible and within 72 hours. Step 7 lists local places to ask about it.

Step 2: Learn the test types and window periods

An HIV test cannot find HIV right after an exposure. The time between exposure and when a test can reliably show a result is called the window period. The CDC publishes window periods by test type.

Test type	What it looks for	CDC window period
Nucleic acid test (NAT, an RNA test)	The virus itself, in blood from a vein	10 to 33 days after exposure
Antigen/antibody test, lab (blood from a vein)	Antibodies and a viral protein called p24	18 to 45 days after exposure
Antigen/antibody test, fingerstick	Antibodies and p24	18 to 90 days after exposure
Antibody test	Antibodies only	23 to 90 days after exposure

The CDC says most rapid tests and home self-tests are antibody tests. It also notes that antibody tests using blood from a vein usually detect HIV sooner than tests using blood from a finger stick or oral fluid. Some rapid tests are antigen/antibody tests, which look for more than one marker.

If you test before the end of the window for your test, the CDC advises getting tested again after the window period has passed. A single negative result inside the window cannot tell you the whole story.

Step 3: Pick a Tucson site

Tucson has public health, nonprofit and community health center options. A short summary appears below, and the next section gives details. You can also compare options on the local testing list.

Think about three things: cost, whether you want a rapid result, and whether you need to be seen quickly. Free testing and sliding fee scales exist, so cost should not keep you from testing.

Step 4: Call to confirm hours, cost and whether you need an appointment

Do this step even if a clinic says it takes walk-ins. Hours and walk-in rules in Tucson differ by site and can change.

Ask these questions:

Is HIV testing available today, and do I need an appointment?
Is the test a rapid test? How long until I have a result?
Is the test free for me, or is there a sliding fee? What is the cost?
Is it a fingerstick, a blood draw from a vein, or an oral swab?
How do I get a result if it is not given the same day?

Write the answers down so you can compare.

Step 5: Go to the visit

At the visit, expect a brief conversation. Staff usually ask why you are testing, explain the test and ask for your consent. You do not need to share more than you want to. You can ask what is recorded and who sees it.

Then comes the test. For a rapid fingerstick, a staff member pricks your finger and collects a small blood sample. For a blood draw, a staff member takes blood from your arm. The collection itself usually takes a few minutes.

Step 6: Wait for and talk through the result

With a rapid test, you may wait in the clinic for about 20 minutes. The Southern Arizona AIDS Foundation (SAAF) says it uses a Rapid HIV Antigen and Antibody Test, with results available in approximately 20 minutes.

A lab-based test, such as a blood draw, can take longer. Ask the clinic how and when you will hear back.

Whatever the result, ask the staff to explain it in plain words and to tell you about next steps. That is part of their job, and it is a good time to ask about retesting dates and prevention options.

Step 7: Plan your next step

Your next step depends on the result and on timing.

If the result is negative and your last possible exposure was before the window period for that test, a clinician can talk with you about how reliable the result is and when to test again.
If the result is negative but you tested early, ask about retesting after the window period.
If the result is reactive, you will be offered a follow-up test, covered below.
If you want to prevent HIV in the future, ask about pre-exposure prophylaxis (PrEP), a medicine a clinician prescribes. Several Tucson sites offer PrEP or PrEP navigation.

Free and low-cost HIV testing in Tucson

These are the places that publish HIV testing in Tucson. Hours, eligibility and fees can change, so call before you go.

Pima County Health Department clinics

Pima County runs two clinics that list HIV and STI testing, and both are listed with PrEP Starter Packs and PrEP navigation on the county's HIV and STI page.

Theresa Lee Public Health Center, 1493 W. Commerce Court, Tucson, AZ 85746. Phone 520-724-7900.
Pima County Northwest Clinic, 1010 W. Miracle Mile, Tucson, AZ 85705. Phone 520-724-2880.

The county's HIV and STI page says it uses a sliding fee scale based on income and that nobody will be turned away for inability to pay. It does not list a fixed price for testing, so ask when you call.

The county's two pages disagree on walk-ins. The HIV and STI page says clients are seen on a walk-in basis and that wait times can vary. The county Clinic Hours page lists HIV and STI testing at Theresa Lee as by appointment only. Because of that conflict, call 520-724-7900 before you go.

The Clinic Hours page also says there are no services from noon to 1 p.m. daily, and that the clinics are closed the first Thursday of every month. For the Northwest Clinic, the page lists HIV and STI testing but gives no hours for it, so call 520-724-2880.

Pima County also says minors do not need parental consent. Arizona law, A.R.S. 44-132.01, says a minor who may have a venereal disease can consent to medical care for its diagnosis or treatment, and a parent's consent is not required. If you are under 18, ask the clinic how that applies to your visit.

Southern Arizona AIDS Foundation (SAAF Health)

SAAF is at 375 S. Euclid Avenue, Tucson, AZ 85719. Phone 520-628-7223, or toll-free 800-771-9054.

SAAF's testing page says making an appointment is the best option. Walk-ins depend on availability. Its listed testing hours are:

Tuesday, Thursday and Friday, 8:15 a.m. to 12:00 p.m., with the last appointment at 11:15
Monday, Tuesday and Wednesday, 1:15 to 5:00 p.m., with the last appointment at 4:15
Wednesday, 5:00 to 7:00 p.m., walk-in only

The CDC GetTested listing for SAAF lists free HIV, hepatitis B, hepatitis C and STI tests, and says to contact SAAF about eligibility. SAAF's own testing page describes HIV testing, so ask the staff what other tests are offered when you call. SAAF also lists PrEP and PEP.

El Rio Health

El Rio Health is a federally qualified health center with testing at two Tucson locations in the CDC GetTested directory. Phone 520-670-3909 for both.

Congress Street, 839 W Congress St, Tucson, AZ 85745
Southeast Campus, 6950 E Golf Links Rd, Tucson, AZ 85730

The CDC listing says an appointment is required and that HIV testing is done by blood draw. It says insurance, Medicaid, Medicare and a sliding scale are accepted at Congress Street, and to contact the organization about eligibility. The directory notes that hours may change, and El Rio's own page for the Southeast Campus does not mention HIV testing. Call to confirm before you go.

Planned Parenthood Southern Arizona Regional Health Center

This center is at 2255 N Wyatt Dr, Tucson, AZ 85712. The 211 Arizona listing gives the phone as 520-408-7526 and says walk-ins are accepted. It lists fees only as varying, and it shows hours of Monday, Tuesday and Friday 7 a.m. to 4 p.m., Wednesday 8 a.m. to 4 p.m. and Thursday 9 a.m. to 4 p.m. Other directories show a different phone number and hours, so confirm by phone before you go.

Other places to ask about PEP and HIV care

The Pima County HIV and STI page also lists Banner University Medical Center and the University of Arizona Petersen HIV Clinics (520-626-8598) for PrEP, PEP and HIV care. It lists the Banner Emergency Department at 1501 N. Campbell Ave for urgent post-exposure care.

Free at-home HIV test kits

Get Tested AZ (a program of HIV AZ and Aunt Rita's, with Southwest Center) offers free at-home HIV test kits using an oral swab, with results in about 20 minutes, after a short survey that decides which free test you qualify for. The page does not mention Tucson or Pima County and does not state eligibility rules. Its free STI testing is in person through Sonora Quest Laboratories, with possible eligibility rules. Check the program's page for current details.

To find more places, the CDC runs a testing locator at gettested.cdc.gov.

Tips for a smoother visit

Call first. Tucson clinic pages and directories disagree on walk-ins and hours. A two-minute call prevents a wasted trip.
Avoid the noon hour and the first Thursday. Pima County clinics list no services from noon to 1 p.m. and are closed the first Thursday of the month.
Ask about timing. A clinician can tell you which test fits your exposure date and when to retest.
Ask what else is available. Many sites also offer STI testing, PrEP information and vaccines. You can ask for what you want without explaining why.
Ask about privacy. You can ask how results are shared and who has access to them.
Bring someone if it helps. A friend can wait with you. Many people find it easier that way.

Common mistakes to avoid

Testing too soon and stopping there. A test taken inside its window period may not be reliable. The CDC advises retesting after the window.
Assuming every rapid test works the same way. Rapid antibody tests and rapid antigen/antibody tests have different CDC window periods.
Skipping the follow-up call. If a clinic says it will contact you, make sure it has a working number and ask how to reach it yourself.
Waiting on a possible recent exposure. If it has been a few days, ask right away about PEP rather than waiting for a routine test slot.
Letting cost decide. Pima County says nobody is turned away for inability to pay, and SAAF's CDC listing includes free HIV testing. Ask about these options before you decide not to go.
Stopping at one test. HIV is one part of sexual health. A clinician can talk with you about syphilis, chlamydia, gonorrhea and others at the same visit.

What your result can mean

Results are explained by the clinic. This section describes how the CDC describes the main outcomes. It does not replace that conversation.

A negative result

A negative result means the test did not find signs of HIV in the sample. It is most reliable when you took the test after the window period for that test type. If you tested earlier, the CDC advises testing again after the window has passed, and a clinician can help set that date.

A reactive result on a rapid test

A reactive rapid result is preliminary. It is not a final answer on its own. The CDC says a reactive result needs follow-up testing to confirm, and the clinic will usually arrange that for you right away. Staff are used to this conversation and can walk you through each step.

Many people feel scared or stunned when they hear this. That is a normal reaction. Ask the staff to slow down and repeat anything that is unclear.

If follow-up testing confirms HIV

HIV cannot be cured, but it is treatable. A clinician prescribes HIV medicine, and the CDC says people who take it as prescribed and reach an undetectable viral load can stay healthy and will not pass HIV to a sexual partner. Treatment starts with a clinician, who will decide what is right for you. Tucson sites such as SAAF, El Rio Health and the Petersen HIV Clinics list HIV care or navigation.

An unclear or invalid result

Sometimes a test cannot give a clear answer, or the sample needs to be repeated. Staff will tell you what to do next. It does not by itself say anything about your health.

Why local testing matters

Arizona reported 975 new HIV cases in 2022, a 20 percent increase from 852 in 2021, according to KOLD News citing the Arizona Department of Health Services. For Pima County, the same report listed 141 new HIV cases, a 15 percent increase. Those are counts, and a rate per 100,000 people was not found. The Pima County HIV and STI page also says syphilis is on the rise in Pima County, which is one reason a clinician may suggest other tests at the same visit.

These figures are not a reason for alarm. They are a reason that regular, low-barrier testing is available here, and that using it is an ordinary part of looking after your health.
