The CDC recommends that everyone ages 13 to 64 get tested for HIV at least once, and that people with ongoing risk test at least once a year. At Urgent Care Center of Westmont in Westmont, IL, also known as Immediate Care Center of Westmont, you can walk in for a private, discreet HIV test and talk with our team about your results and next steps.

If you think you were exposed to HIV in the last 72 hours, do not wait for a test. The CDC says medicine called PEP (post-exposure prophylaxis) must be started within 72 hours to prevent HIV. Call us right away at (630) 324-6825, or go to the nearest emergency room.

Key facts

  • About two-thirds of people get flu-like symptoms 2 to 4 weeks after getting HIV, but some have none (HIV.gov).
  • PrEP lowers the risk of getting HIV from sex by about 99% when taken as prescribed (HIV.gov).
  • People with HIV who take treatment and keep an undetectable viral load do not pass HIV to partners through sex.
  • A negative HIV test is needed before starting PrEP, and testing continues while you take it.

Why HIV testing matters and who should test

HIV.gov notes that knowing your status helps you make informed decisions about your health and protect your partners. The CDC recommends testing for:

  • Everyone ages 13 to 64, at least once
  • Anyone being tested or treated for another STI
  • People with a new partner or more than one partner since their last test
  • Gay, bisexual and other men who have sex with men, at least yearly; the CDC notes some may benefit from testing every 3 to 6 months
  • Pregnant people, at the first prenatal visit

How HIV testing works at our Westmont, IL clinic

Your visit starts with a private conversation about any recent exposures and your testing history. The provider will recommend the right test and explain what the result can and cannot tell you.

The window period

No HIV test can detect HIV right after exposure. According to the CDC, the window periods are about:

  • 10 to 33 days for a nucleic acid test (NAT)
  • 18 to 45 days for a lab antigen/antibody blood test
  • 18 to 90 days for a rapid antigen/antibody test
  • 23 to 90 days for an antibody test

If you test negative but had a possible exposure within the window period, you should test again after it ends.

Understanding your result

HIV.gov explains that a positive result needs a follow-up test to confirm it. If HIV is confirmed, the provider will help connect you with HIV care. If you test negative, you can ask about ways to lower your risk, including PrEP and condoms.

You can also ask to be tested for chlamydia, gonorrhea, hepatitis or other STIs during the same visit.

A possible HIV exposure is time-sensitive. The CDC says PEP must start within 72 hours and is taken daily for 28 days. You can get PEP from a health care provider, an emergency room or an urgent care center. Call us first to ask, or go to the nearest emergency room.

Early HIV symptoms

HIV.gov says about two-thirds of people have flu-like symptoms within 2 to 4 weeks of getting HIV. They can last a few days to several weeks:

  • Fever and chills
  • Rash
  • Night sweats and muscle aches
  • Sore throat and tiredness
  • Swollen lymph nodes
  • Mouth sores
These symptoms have many other causes, and some people with HIV have no symptoms at all. The only way to know is to get tested.

PrEP vs. PEP

PrEP (before exposure)

  • For HIV-negative people with ongoing risk
  • Daily pills or long-acting shots
  • Cuts the risk of HIV from sex by about 99% when taken as prescribed
  • Needs an HIV test before starting and regular tests after

PEP (after exposure)

  • For a possible exposure in the last 72 hours
  • Must be started within 72 hours
  • Taken every day for 28 days
  • If exposures keep happening, ask about PrEP instead

HIV.gov says people who should consider PrEP include those who have a partner with HIV, don't always use condoms, recently had an STI, or have needed PEP more than once. Ask your clinician whether PrEP fits you and how to get started.

HIV care has changed a great deal. HIV.gov explains that HIV medicine, called antiretroviral therapy, taken as prescribed can lower the virus to an undetectable level. People who keep an undetectable viral load can live long, healthy lives and do not pass HIV to partners through sex.

If your test is positive, a follow-up test confirms it, and our team can help you connect with an HIV care provider. Getting into care early protects your health and your partners.

Common questions

How soon after exposure can I get tested?

It depends on the test. The CDC says a nucleic acid test can detect HIV about 10 to 33 days after exposure, and other tests take longer. If you were exposed in the last 72 hours, ask about PEP first.

Is HIV testing confidential?

Yes. Your test and results are part of your private medical record. You can ask our team about privacy when you check in.

What happens if my test is positive?

A positive result needs a follow-up test to confirm it. If HIV is confirmed, our team can help you connect with a provider for HIV care.

How often should I get tested?

Everyone ages 13 to 64 should test at least once. People with ongoing risk should test at least once a year, and some may benefit from testing every 3 to 6 months.

Can you test positive for HIV and not have it?

It is uncommon, but it can happen. That is why every positive screening result is confirmed with a follow-up test before a diagnosis is made. Try not to make decisions based on one screening result. Your clinician explains what your result means and what comes next.

Does a regular blood test check for HIV?

No. Routine blood work, such as a blood count or metabolic panel, does not test for HIV. Ask for an HIV test by name, or say yes when your clinician offers one. CDC recommends that everyone ages 13 to 64 be tested at least once.

Who should consider PrEP?

HIV.gov lists HIV-negative people who have had anal or vaginal sex in the past 6 months and have a partner with HIV, don't always use condoms or recently had an STI. People who inject drugs and share equipment, and people who have needed PEP more than once, should also ask about it.

What are the first signs of HIV?

Early signs are often flu-like: fever, chills, rash, night sweats, muscle aches, sore throat, tiredness, swollen lymph nodes or mouth sores, usually 2 to 4 weeks after infection. Many people have no symptoms. HIV.gov says the only way to know for sure is to get tested.
