If you learn that you have HIV, you can get treatment. Getting treatment sooner can improve your health and help you live longer. Being on effective treatment will lower the amount of HIV in your body and your chances of transmitting HIV.
A negative HIV test result shows that you don't have HIV antibodies. However, if you test during the window period, the period after exposure but before the test can find antibodies, the test may not detect HIV even when you have been exposed.
Remember that the result is only good until the next time you have unprotected sex or share needles or other injection equipment.
Knowing your HIV status is a source of strength, not a reason for fear. Getting an HIV test is the only way to know if you have HIV or not.
Know your HIV status. The first step in protecting your health and the health of your partners is to make sure you know your HIV status. When you know your status, you can take care of yourself, and you are less likely to give the virus to others. Research shows that if people know they have HIV, they often take steps to protect their partners.

Know your risk. You may wonder how often you need to get tested for HIV. That depends on your risk for getting HIV. A general rule is to get tested at least once a year. But remember: your HIV test result expires every time you have risky sex.
CDC recently reported that gay and bisexual men may benefit from getting an HIV test more often, every 3 to 6 months. To understand your risk, you need to also understand the window period. This is a period right after someone gets infected but before infection shows up on an HIV test.
Know how to stay healthy. There are many reasons for getting tested for HIV. The most important reason is that you will have the information you need to make good decisions about your sexual health and your future. In addition to staying on top of your HIV status, check out these tips on what additional tests, vaccinations, and other steps gay and bisexual men can take to stay healthy.
CDC recommends that everyone between the ages of 13 and 64 be tested for HIV at least once as part of routine health care. Almost 1 in 5 people in the United States who have HIV do not know they are infected.
HIV is spread through risky sex and drug-use behaviors, so people who engage in these behaviors should get tested more often. If you answer yes to any of the following questions, you should definitely get an HIV test:
If you continue having unsafe sex or sharing injection drug equipment, you should get tested at least once a year. Sexually active gay and bisexual men may benefit from more frequent testing (e.g., every 3 to 6 months).
You should also get tested if
Getting tested can give you some important information and can help keep you—and others—safe:
Some people who test positive for HIV were not aware of their risk. For example, 6 in 10 young people with HIV do not know that they have it, and CDC's surveys have found that 4 in 10 sexually active high school students did not use a condom the last time they had sex.
That is why CDC recommends that providers in all health care settings make HIV testing a routine part of medical care for patients aged 13 to 64, unless the patient refuses (opts out). This practice would get more people tested and help reduce the stigma around testing.
Even if you have been in a long-term relationship with one person, you should find out for sure whether you or your partner has HIV. If you are both HIV-negative and you both stay faithful (monogamous) and do not have other risks for HIV infection, then you probably will not need another HIV test unless your situation changes.
The immune system usually takes 2 to 8 weeks to make antibodies against HIV (the average is 25 days). Most HIV tests look for these antibodies rather than the virus itself. The period after exposure but before the test can find antibodies is called the window period. Because the level of antibody in oral fluid is lower than it is in blood, blood tests tend to find infection sooner after exposure than do oral fluid tests. In addition, most blood-based lab tests find infection before rapid HIV tests.
A few people will have a longer window period, so if you get a negative test result in the first 3 months after possible exposure, you should get a repeat test after 3 months. Although in very rare cases, it can take up to 6 months to develop antibodies to HIV, 97% of people develop antibodies in the first 3 months after they are infected.
Between the time you were possibly exposed and when you receive your test results:
Many places offer free, fast, and confidential HIV tests. Here's how to find an HIV testing site near you:
You can also ask your health care provider for an HIV test. Many medical clinics, substance abuse programs, community health centers, and hospitals offer them, too.
The most common HIV test is the screening (immunoassay) test, which measures the antibodies that your body makes against HIV. The immunoassay may be conducted in a lab or with a rapid test at the testing site. It may be performed on blood, oral fluid (not saliva), or urine. Blood tests are more accurate than oral fluid or urine tests. Newer immunoassay tests can find HIV as soon as 3 weeks after exposure to the virus.
The rapid test is an immunoassay test used for screening, and it produces quick results, in less than 20 minutes. Rapid tests use blood or oral fluid to look for antibodies to HIV. If an immunoassay (lab test or rapid test) is conducted during the window period (i.e., the period after exposure but before the test can find antibodies), the test may not find antibodies and may give a false-negative result. All immunoassays that are positive need a follow-up test to confirm the result.
Follow-up supplemental diagnostic testing is performed if the first immunoassay result is positive. Supplemental tests include a Western blot or immunofluorescence assay, which detect antibodies; a differentiation test, which distinguishes HIV-1 from HIV-2; or an HIV-1 nucleic acid test, which looks for the virus directly.
Immunoassay tests are generally very accurate, but supplemental testing allows you and your health care provider to be sure the diagnosis is right. If your first test is a rapid test, and it is positive, you will be directed to a medical setting to get supplemental testing. If your first test is a lab test, and it is positive, the lab will conduct supplemental testing, usually on the same blood or oral fluid sample as the first test.
False-positive tests are rare. If tests are conducted during the window period, they can give a false-negative result.
Home testing kits are available in most drugstores or online. There are two types:
RNA tests detect HIV directly (instead of the antibodies to HIV) and thus can detect the virus at about 10 days after infection because there is no need to wait for your body to develop antibodies. These tests cost more than antibody tests and are generally not used as a screening test, although your doctor may order one as part of a clinical workup.
When it is time to take the test, a health care provider will take your sample (blood or oral fluid), and you may be able to wait for the results (if it is a rapid HIV test). If the test comes back negative, you should receive some HIV risk reduction counseling. You are finished with testing for the time being.
If your test comes back positive, you will need to get a supplemental test, which the testing site will arrange.
Your health care provider or counselor may talk with you about your risk factors, answer questions about your general health, and discuss next steps with you, especially if your result is positive.
If you receive a negative HIV test result within the "window period", you need to have a follow-up test to confirm your results. For more information, see What is the window period and what does it mean for HIV testing? You can confirm when you need to be retested with a health professional.
If you receive a negative test after the window period, remember there are things you can do to stay negative.
No. Your HIV test result reveals only your HIV status. HIV is not necessarily transmitted every time you have sex. Therefore, taking an HIV test is not a way to find out if your partner is infected. Ask your partner if he or she has been tested for HIV and about his or her risk behaviors, both now and in the past. Consider getting tested together, which is often referred to as couples testing.
If you had a rapid screening test, the testing site will arrange a supplemental test to make sure the screening test result was correct. If you had a lab-based screening test, the lab will conduct a supplemental test with the same sample. If the supplemental test is also positive, you will be diagnosed as HIV-positive.
If you test HIV-positive, the sooner you take steps to protect your health, the better. Early treatment with antiretroviral drugs and a healthy lifestyle can help you stay well. Prompt medical care may delay the onset of AIDS and prevent some life-threatening conditions.
Here are some important steps you can take right away to protect your health:
Take the following steps to avoid giving HIV to anyone else:
Not necessarily. Being HIV-positive does not mean you have AIDS for sure. AIDS is the most advanced stage of HIV. Proper treatment can keep you from developing AIDS.
See Basic Information About HIV and AIDS for more information.
Your test results are protected by state and federal privacy laws. Whether anyone can know about your test results or your HIV status depends on what kind of test you take: confidential or anonymous. Some states only offer confidential testing.
With confidential testing, if you test positive for HIV or another STI, the test results and your name will be reported to the state and local health department to help public health officials get better estimates of the rates of HIV in the state. The state health department will then remove all personal information about you (name, address, etc.) and share the remaining non-identifying information with CDC. CDC does not share this information with anyone else, including insurance companies.
For more information, see CDC's Questions about Privacy, Insurance, and Cost.
Whether you share, or disclose, your status to others is your decision.
If you test positive for HIV, your sex or drug-using partners may also be infected. It is important that they know they have been exposed so that they can be tested too.
You can tell them yourself, but if you have been threatened or injured by your partner or if you are nervous about disclosure for any other reason, you can ask your doctor or the local health department to tell them for you. Health departments do not reveal your name to your partners. They will only tell your partners that they have been exposed to HIV and should get tested.
Most states have laws that require you to tell your sex partners if you are HIV-positive before you have sex (anal, vaginal, or oral) or share drugs. You can be charged with a crime in many places if you don't tell—even if your partner doesn't become infected.
In most cases, your family and friends will not know your test results or HIV status unless you tell them yourself. Although telling your family that you have HIV may seem hard, you should know that disclosure actually has many benefits—studies have shown that people who disclose their HIV status respond better to treatment than those who do not.
If you are under age 18, however, some states allow your health care provider to tell your parent(s) that you received services for sexually transmitted infections, including HIV, if they think doing so is in your best interest. For more information, see the Guttmacher Institute's State Policies in Brief: Minors' Access to STI Services.
In most cases, your employer will not know your HIV status unless you tell. But your employer does have a right to ask if you have any health conditions that would affect your ability to do your job or pose a serious risk to others. (An example might be a health care professional, like a surgeon, who does procedures where there is a risk of blood or other body fluids being exchanged.)
If you have health insurance through your employer, the insurance company cannot legally tell your employer that you have HIV. But it is possible that your employer could find out if the insurance company provides detailed information to your employer about the benefits it pays or the costs of insurance.
All people with HIV are covered under the Americans with Disabilities Act. This means that your employer cannot discriminate against you because of your HIV status as long as you can do your job. For more information, see AIDS.gov's Civil Rights.
Ask your insurer if HIV screening is available without a co-pay, as required by the Affordable Care Act for most health plans. If you do not have medical insurance or your insurance will not pay for an HIV test, there are places where you can get an HIV test at a reduced cost or for free. See "Where can I get tested?" for more information.
If you have insurance, your insurer may pay for treatment. If you do not have insurance, or your insurer will not pay for treatment, government programs, such as Medicaid, Medicare, Ryan White Care Act treatment centers, and community health centers may be able to help if you meet their rules for eligibility (usually low income and/or disability). CDC is working with its federal partners that oversee these programs to make sure that all people who need treatment can get it. Your health care provider or local public health department can direct you to HIV treatment programs.
For more information, see The Affordable Care Act and HIV/AIDS.
