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 Columbia is a short process. Many people finish a rapid test in one visit, and several local sites offer testing at no charge. This guide walks you through it step by step, from choosing a test to understanding the result.

The CDC recommends that everyone ages 13 to 64 get tested for HIV at least once. The CDC also recommends testing at least once a year for people with a higher likelihood of exposure. A test is a routine health step, and a clinician can help you decide how often is right for you.

What you will need

You do not need much. Here is a short checklist.

A photo ID, if you have one. Some clinics ask for it. If you do not have one, ask the clinic what it accepts.
Your insurance card, if you have insurance. Several Columbia sites accept insurance, Medicaid or Medicare. Several also offer free HIV testing, so lack of insurance should not stop you.
A rough timeline. Write down the date of your most recent possible exposure. This helps the tester choose the right test.
A list of questions. Examples are how long results take, what happens after a reactive result and whether PrEP is available.
A phone. Hours and walk-in rules can change, so a quick call before you go saves a trip.
A support person, if you want one. This is optional.

Step 1: Know the three kinds of HIV tests

The CDC describes three main types of HIV tests. The type matters because each one can detect HIV at a different point after exposure.

Antibody tests

These look for antibodies, which the body makes in response to HIV. Most rapid tests and self-tests are antibody tests. The CDC says antibody tests on blood from a vein can detect HIV 23 to 72 days after exposure. Tests using a fingerstick or oral fluid can take longer, with a window of 23 to 90 days.

Antigen/antibody tests

These look for both antibodies and a part of the virus called p24 antigen. The CDC says a lab test on blood from a vein can detect HIV 18 to 45 days after exposure. A rapid antigen/antibody test using a fingerstick can take longer, 18 to 90 days.

Nucleic acid tests (NAT, or RNA tests)

These look for the virus itself. The CDC says a NAT can usually detect HIV 10 to 33 days after exposure. NATs are not usually the first choice for routine testing. A clinician may suggest one after a recent, specific exposure or if early symptoms are present.

The CDC calls the time between exposure and a test's ability to detect HIV the window period. A test taken inside the window period may not show an accurate picture. If your exposure was recent, ask the clinic whether retesting later makes sense.

Step 2: Understand what a rapid HIV test is

A rapid HIV test gives a preliminary result in a short time. Depending on the test, the sample is a fingerstick of blood or a swab of oral fluid. According to the CDC, rapid tests generally return results in about 30 minutes or less. Clinics may use a rapid antibody test or a rapid antigen/antibody test, so it helps to ask which one you are getting.

Rapid does not mean less careful. It means the first result is available during your visit instead of days later. Any reactive rapid result needs follow-up testing, which is covered in Step 6.

Step 3: Pick a place for HIV testing in Columbia, SC

Several sites around Columbia offer HIV testing. Details below come from each organization's published listing, from CDC directories where noted, or from the South Carolina Department of Public Health (DPH). Hours and walk-in policies can change, so confirm by phone first. For a fuller comparison of clinics and costs, see our guide to STD testing in Columbia and what it costs, or browse the local testing list.

Free options

PALSS (Palmetto AIDS Life Support Services), 2638 Two Notch Rd, Ste 108, (803) 779-7257. The CDC NPIN listing shows free HIV tests and rapid HIV testing. It lists walk-in testing on Tuesdays from 3 to 8 p.m. and Thursdays from 3 to 7 p.m. It also lists walk-in only testing on the 1st and 3rd Saturdays from 10 a.m. to 2 p.m. The CDC GetTested listing for PALSS says an appointment is required, so call to confirm which applies.
CAN Community Health, 1911 Hampton St., (803) 849-8430. The clinic's page lists free rapid and home HIV testing. It says walk-ins are accepted during regular hours. Posted hours are Monday through Thursday 8:30 a.m. to 5:30 p.m. and Friday 8:30 a.m. to 12:30 p.m. Extended Thursday hours and some Saturday hours are offered on select dates. A CDC NPIN listing for CAN says an appointment is required, so call ahead.
AHF Healthcare Center, 4100 N Main St, Suite 102, (803) 223-9895. The CDC GetTested listing shows a free HIV test with rapid HIV testing and says an appointment is required. It does not list hours.
Cooperative Health, Waverly Family Practice, 1228 Harden St, Ste C, (803) 748-1181. CDC GetTested lists free HIV tests, rapid and blood draw, with an appointment required. Insurance, Medicaid, Medicare and a sliding scale are accepted for other services.

Low-cost, insurance and other options

Cooperative Health, Five Points Walk-In Center, 1228 Harden St, Ste A, (803) 722-1565. CDC GetTested lists HIV testing by blood draw and says no appointment is required. It lists a sliding scale and acceptance of insurance, Medicaid and Medicare. The listing does not give hours.
Planned Parenthood South Atlantic, Columbia Health Center, 2712 Middleburg Dr, Ste 107, (803) 256-4908. The CDC NPIN listing shows rapid HIV testing. It lists Monday 9 a.m. to 5 p.m., Tuesday 9 a.m. to 3 p.m., Wednesday 9 a.m. to 5 p.m., Thursday 10 a.m. to 6 p.m. and Friday 9 a.m. to 2 p.m. Insurance and Medicaid are accepted. Ask the center about eligibility and cost.
Richland County Health Department, 2000 Hampton St. The DPH says STD/HIV/Hep C services continue at this site. DPH does not list a clinic phone number, hours or fees on that page. Call the DPH Care Line at 1-855-472-3432 to make an appointment and ask about cost. DPH also notes the services may move to the former Columbia Place Mall site in the future.

You can also search by ZIP code at gettested.cdc.gov, the CDC's testing locator.

Step 4: Consider a free home test from the state

If you prefer privacy, DPH runs an In-Home HIV Testing Program. According to DPH, South Carolina residents age 17 or older can request a free oral fluid self-test kit. The limit is one kit every 90 days, and you request it through an online survey. Questions can go to [email protected] or the STD/HIV Hotline at 1-800-322-2437.

Self-tests are antibody tests, so the CDC window period for antibody tests applies. A reactive self-test result needs follow-up testing with a clinician or clinic, just like a reactive rapid test in a clinic.

Step 5: Take the test

Here is what usually happens at a clinic visit.

Check in. You may fill out a short form. Questions about your health and exposures help the tester pick the right test. They are not a judgment.
Talk with the tester. Tell them the date of any recent exposure. Ask which test is being used and when it can detect HIV.
Give a sample. This may be an oral swab, a fingerstick or a blood draw from a vein.
Wait for the result. For a rapid test, you usually wait in the clinic. For a lab test, the clinic will tell you how and when you will hear back.
Talk about next steps. This is a good time to ask about retesting, PrEP, PEP and testing for other infections.

If you are under 18, South Carolina law may be on your side. S.C. Code Ann. § 63-5-350 allows health services to be provided to minors of any age without parent or guardian consent when the authorized provider considers them necessary. The statute does not mention STDs by name. The Guttmacher Institute lists South Carolina as a state where minors can consent to STI testing and treatment. Ask the clinic about its own policies before your visit.

Step 6: Understand your result

A test can only tell you what it found at the time of the test. It cannot tell you everything about your health. A clinician can explain what a result means for you.

If the result is non-reactive (negative)

A non-reactive result generally means the test did not detect HIV. If you were tested inside the window period for that test, ask whether a repeat test is a good idea. The CDC says that if a test was done too soon after exposure, retesting later may be recommended.

If the result is reactive

A reactive result on a rapid test or self-test is preliminary. It is not a final diagnosis. The CDC says a reactive result needs follow-up testing to confirm. Usually this means a laboratory test run on a blood sample.

A reactive screening result can feel overwhelming. Many people feel several emotions at once, and that is normal. You do not have to sort it out alone. The clinic can connect you with a clinician and a counselor.

If follow-up testing confirms HIV, a clinician can prescribe HIV medicine. The CDC says HIV cannot be cured, but it is treatable. The CDC also says that people who take HIV medicine as prescribed and reach an undetectable viral load have effectively no risk of passing HIV to a partner through sex. A clinician can explain what that means in your situation.

If the result is unclear

Occasionally a result is indeterminate or inconclusive. The clinic will explain the next step, which is usually another test after some time or a different type of test.

Tips for a smooth visit

Call first. Hours and walk-in rules vary, and some listings disagree about whether an appointment is needed. A short call settles it.
Ask which test is used. Knowing whether it is an antibody, antigen/antibody or NAT test helps you interpret the window period.
Ask about other tests. Several Columbia sites also test for chlamydia, gonorrhea and syphilis. CAN Community Health also lists herpes, hepatitis B and C, and trichomoniasis testing. Check what your chosen site offers.
Ask about cost before you go. The Richland County Health Department page does not list fees. Planned Parenthood lists cost as depending on eligibility. A phone call gives a clear answer.
Bring questions. Testing is a good moment to ask about PrEP. DPH lists a South Carolina PrEP provider directory and PrEP navigation resources on its PrEP page.
Know about PEP. The CDC says post-exposure prophylaxis (PEP) should be started as soon as possible after a possible exposure, within 72 hours. If you think you had a recent exposure, call a clinic that offers PEP right away. CAN Community Health and Planned Parenthood list PEP among their services.

Common mistakes to avoid

Testing too early and stopping there. A test taken inside its window period may not be able to detect HIV. Ask about a repeat test.
Treating a reactive rapid result as final. It needs follow-up testing, as the CDC explains. Do not assume either way until that follow-up is done.
Skipping follow-up. If a clinic asks you to come back for another test or a lab draw, go. It is the step that gives a clearer answer.
Assuming a site is open. Posted hours come from directory listings that may be out of date. Call first.
Avoiding the test out of worry about cost. Several local sites list free HIV testing. DPH also runs a free home testing program.
Waiting for a perfect moment. Testing is routine care. There is no wrong time to ask a clinic about it.

What to expect afterward

After a non-reactive result, the clinic may suggest when to test again, depending on your exposure and the type of test used. After a reactive result, expect a follow-up test and a conversation about next steps. In both cases, you can ask about PrEP, PEP, condoms and testing for other infections.

South Carolina law requires physicians to report certain infectious diseases to the county health department. S.C. Code Ann. § 44-29-10 describes this requirement. If you have questions about privacy or reporting, ask the clinic before testing. The staff can explain how your information is handled.

Where to go next

If you are ready to get tested, pick one site from the list above and call. For a free option with published walk-in hours, PALSS and CAN Community Health are good places to start. Confirm hours by phone before you go. For confidential questions, the DPH STD/HIV Hotline is 1-800-322-2437. To see other options, use gettested.cdc.gov.
