HIV Testing

4.5.1 Standard

The majority of healthcare venues carry out “standard” HIV testing. This means a tube of blood is collected in the clinic, hospital or physician’s office and sent to the medical laboratory along with a requisition ordering an HIV test. Standard testing can be done in any type of setting . Test results are generally available within one week.

4.5.2 Point-of-Care or rapid testing

Testing Recommendations And Requirements

The U.S. Centers for Disease Control and Prevention recommends everyone aged 13-64, receive at least one HIV test as a part of routine health care and more frequent testing, at least annually, for those at higher risk. Per the CDC, individuals who may benefit from at least annual screening include:

  • sexually active gay or bisexual men
  • individuals who have had sex with an HIV-positive partner
  • individuals who have had more than one partner since their last HIV test
  • those who have shared needles or works to inject drugs
  • people who have exchanged sex for drugs or money
  • individuals who have another sexually transmitted disease, hepatitis, or tuberculosis
  • those who have had sex with someone who has participated in any of the above activities or with someone with an unknown sexual history

Certain factors are known to reduce the risk of HIV transmission including condom use, antiretroviral treatment leading to durable viral load suppression among those with HIV, and the use of pre-exposure prophylaxis among those at increased risk for HIV.Additionally, HIV testing is recommended for all pregnant women and for any newborn whose mothers HIV status is unknown. Treatment provided to pregnant HIV-positive people early in pregnancy can reduce the risk of transmitting HIV to 1% or less. HIV testing is also recommended for anyone who has been sexually assaulted.

CDC recommends that all HIV screening be voluntary, and opt-out vs. opt-in .

HIV and AIDS tests you perform at home look for antibodies to the HIV virus inside your body. This is the virus that causes AIDS. The HIV virus attacks immune cells that help your body fight off infection. Over time this can weaken your immune system and make it harder to avoid illness. Home HIV and AIDS tests can tell you whether you’ve been exposed to the HIV virus so you can get medical treatment and avoid exposing others.

  • Why Is Paxlovid Eligibility So Narrow

    How do HIV tests work and what

    Part of the reason why Paxlovid seems so restricted is because it will only benefit people at high-risk of severe disease.

    “It does not help people with low risk for severe disease,” Amesh A. Adalja, MD, a senior scholar at the Johns Hopkins Center for Health Security, told Verywell.

    The clinical trial for Paxlovid even required that study participants have at least one characteristic or coexisting condition associated with high risk of progressing to severe COVID.

    Paxlovid can also interact with a long list of medications, which is why not everyone can take it.

    How An Hiv Test Works

    An HIV test is a blood test. It does not detect HIV itself, but looks for a protein found in an HIV cell, or an antibody made by the body to fight HIV.

    HIV tests in the UK are very reliable. They can occasionally produce a positive result which is then found to be negative when tested again. This is called a false positive and is rare, occurring in less than 1 in 1,000 cases.

    Other Factors Influencing Hiv Transmission Risk

    Within each route of transmission, estimates of the risk of transmission vary widely, likely due to the role of behavioural and biological co-factors. Viral load appears to be an important predictor of transmission, regardless of route of transmission. However, the evidence indicates that viral load is not the only determinant, and other co-factors, such as the presence of co-infections, play a role in increasing or decreasing the risk of transmission.

    Viral Load

    The strongest predictor of sexual transmission of HIV is plasma viral load . A dose-response relationship has been observed, where each ten-fold increase in plasma VL resulted in an increased relative risk of transmission of 2.5 to 2.9 per sexual contact. The concentration of HIV in genital secretions also plays a major role in sexual transmission. While there is a strong correlation between HIV concentrations in plasma and in genital secretions, some studies have found genital tract HIV shedding in 20% to 30% of men and women without detectable plasma viral load. Much of what is known about the impact of viral load on the sexual transmission of HIV is derived from studies of heterosexual populations. Very little is known about the relationship between HIV viral load and rate of transmission through anal intercourse.

    What Kind Of Hiv Tests Are There

    Rapid HIV tests give you results in about 20 minutes. Other tests take longer because they need to be sent out to a lab. HIV tests are usually painless you just gently rub the inside of your cheek with a soft swab. Sometimes youll give a blood sample for testing.

    You can test yourself for HIV using an at-home HIV testing kit. With the OraQuick In-Home HIV Test, you swab your gums and test the sample yourself. You get results in 20 minutes. With the Home Access HIV-1 Test, you prick your finger to get a small amount of blood. You mail your blood sample to a lab, and get your results in about a week. At-home tests are totally anonymous you’re the only person who will know the results. And both types of tests help connect you with counselors who can give you support and advice about treatment if you test positive.

    If a rapid HIV test at a clinic or a home test shows that you have HIV, get a follow-up test to make sure the results are correct.

    Talk to your doctor or the counselor or social worker at the testing site to see if you need to get tested again.

    Some reasons to get tested again include if you:

    • have sex without a condom
    • are a guy who has sex with other guys
    • have had sex with more than three partners in the past year
    • get an STD
    • are a woman and are pregnant

    Why Testing Is Important

    If you’re carrying the HIV virus, early treatment can keep you healthy longer. Treating HIV infection early may slow down damage to the immune system and may help prevent or delay some of the life-threatening infections people with AIDS can develop. By knowing your HIV status, you can also take steps to avoid spreading the virus to other people.

    The HIV virus is transmitted from person to person through sexual contact and contact with blood from an infected person. It can also be passed to an unborn baby through pregnancy, childbirth and breast-feeding. You can carry the HIV virus and not have symptoms initially. That’s why testing is so important. Some experts believe everyone should get tested for HIV at least once.

    When A Person Should Get Tested For Hiv

    If a person believes theyve been exposed to HIV, its important for them to see a healthcare professional as soon as possible.

    No test can accurately detect HIV in the body immediately after exposure. Theres a time frame or window period before a person can be tested for HIV and receive accurate results.

    Regardless of the type of test after potential HIV exposure, a person should get tested again after the window period has passed to be certain.

    People with a higher chance of contracting HIV should get regularly tested .

    A Viral Load Test Will Let You Know If You Are Undetectable

    If youre living with HIV and want to know if youre undetectable, the right test for you is Similar to nucleic acid tests to detect HIV infection, HIV viral load tests measure the number of copies of HIV in a milliliter of your blood. Its recommended that people living with HIV getHIV viral load tests generally every 3 to 6 months, in addition toother lab tests that measure your CD4 count and more.

    The bottom line is that if youre living with HIV and have an undetectable viral load, you will still test positive for HIV if you get tested. But, this is expected, and doesnt mean that your treatment is not working or that you arent undetectable. As always, check with your HIV care provider if you have questions about what HIV test is right for you, or what types of tests will give you the answers you need to best care for your health.

    How Do Hiv Tests Work

    Testing

    When you get HIV, your immune system makes antibodies that try to fight off the infection. The most common type of HIV test looks for these antibodies in your blood or cells from your cheek.

    It usually takes about 3 months for your body to make enough antibodies to show up on an HIV test, but it could be even longer. This time after you first get infected but wont test positive for HIV is called the window period. If you get tested during this time, you can get a negative result even if you do actually have HIV. You also have the biggest chance of giving HIV to other people during the window period.

    What Should I Do If My Test Is Negative

    If your test result is negative, youll probably breathe a big sigh of relief. But dont let down your guard. Its important to protect yourself in the future. Talk to your healthcare provider about whether PrEP is right for you. The PrEP daily pill can reduce your risk of getting HIV from sexual contact by 99%. For IV drug users, it lowers the risk by 74%. PrEP is very important if you are HIV negative and in a stable monogamous relationship with HIV positive partner.

    Even if you take PrEP, its still smart to practice safer sex. Always use a condom to reduce your risk of getting HIV and other STDs.

    What We Know About The Types Of Hiv Tests

    HIV tests are very accurate, but no HIV test can detect HIV immediately after a person gets the virus. Some kinds of tests detect HIV sooner than others. In general, nucleic acid tests can detect HIV the soonest, followed by antigen/antibody tests, and then antibody tests.

    Most rapid tests and self-tests are antibody tests. Your immune system makes antibodies when youre exposed to bacteria or viruses like HIV. Antibody tests look for these antibodies in your blood or oral fluid. In general, antibody tests that use blood from a vein can detect HIV slightly sooner after infection than tests done with blood from a finger prick or with oral fluid.

    More Information With a rapid antibody screening test, results are ready in 30 minutes or less.

    More Information

    A self-test is an antibody test you can buy at a pharmacy or online. There is currently one available FDA-approved self-test, the OraQuick In-Home HIV Test.

    The OraQuick In-Home HIV Test gives fast results at home. You have to swab your mouth to get an oral fluid sample and use a kit to test it. Results are ready in 20 minutes. If the test says you have HIV, you should go to a health care provider to get follow-up testing. The manufacturer provides confidential counseling and refers you to follow-up testing sites.

    Who Should Get Tested For Hiv

    The Centers for Disease Control and Prevention recommends that everyone 13 to 64 years of age get tested for HIV at least once as part of routine health care. As a general rule, people at higher risk for HIV should get tested each year. Sexually active gay and bisexual men may benefit from getting tested more often, such as every 3 to 6 months. If you are over 64 years of age and at risk, your health care provider may recommend HIV testing.

    Factors that increase the risk of HIV include:

    • Having vaginal or anal sex with someone who is HIV positive or whose HIV status you do not know
    • Injecting drugs and sharing needles, syringes, or other drug equipment with others
    • Exchanging sex for money or drugs
    • Having a sexually transmitted disease , such as syphilis
    • Having sex with anyone who has any of the HIV risk factors listed above

    Talk to your health care provider about your risk for HIV and how often you should get tested for HIV.

    How Do The Tests Work

    Most HIV tests use a blood sample, either from a blood draw or finger prick. Others use saliva , but this is a little less accurate than blood tests.

    Some HIV tests look for the virus itself. But most look for the antibodies for HIV. Antibodies are part of the immune system and fight infections. When someone is infected with HIV, the body creates antibodies to fight HIV.

    Testing results may be available that day or can take longer come back.

    What Are The Types Of Hiv Tests

    Who Should Get Tested?

    There are three types of tests used to diagnose HIV infection: antibody tests, antigen/antibody tests, and nucleic acid tests . Your health care provider can determine the appropriate HIV test for you. How soon each test can detect HIV infection differs, because each test has a different window period. The window period is the time between when a person may have been exposed to HIV and when a test can accurately detect HIV infection.

    • Antibody tests check for HIV antibodies in blood or oral fluid. HIV antibodies are disease-fighting proteins that the body produces in response to HIV infection. Most rapid tests and home use tests are antibody tests.
    • Antigen/antibody tests can detect both HIV antibodies and HIV antigens in the blood.
    • NATs look for HIV in the blood.

    A persons initial HIV test will usually be either an antibody test or an antigen/antibody test. NATs are very expensive and not routinely used for HIV screening unless the person had a high-risk exposure or a possible exposure with early symptoms of HIV infection.

    When an HIV test is positive, a follow-up test will be conducted. Sometimes people will need to visit a health care provider to take a follow-up test. Other times, the follow-up test may be performed in a lab using the same blood sample that was provided for the first test. A positive follow-up test confirms that a person has HIV.

    Talk to your health care provider about your HIV risk factors and the best type of HIV test for you.

    Will I Have To Pay For The Test Out Of Pocket

    Most insurance companies pay for HIV tests, as do most plans under the Affordable Care Act. Some pharmacies or community health centers offer free testing too.

    You can pay for some at-home tests with an HSA or FSA. But directly purchased tests may not be covered by private health insurance or Medicaid. Check with your insurance provider or your doctor about reimbursement before buying one.

    Challenges In Hiv Testing

    4.3.1 HIV Testing in the “window period”

    The window period is the time after acquisition of HIV infection when the individual is highly infectious but tests negative on HIV antibody screening because antibodies are not immediately produced. As shown in Figure 4, the timelines associated with the window period have changed with the evolution of more sensitive antibody screening tests. While 1st generation tests detected HIV antibody an average of 60 days following exposure the 4th generation combination tests permit detection of acute HIV infection during the viremic phase. This reduces the window period to approximately 15 to 20 days. Making the diagnosis as early as possible can help prevent onward transmission of the virus, since the person is most infectious during this period. Some jurisdictions provide NAAT testing for high-risk clients , in an effort to identify very early HIV infection.

    4.3.2 Indeterminate results during the window period

    4.3.3 Confirmatory Testing

    The Western Blot assay is not as sensitive as the 3rd and 4th generation screening tests and may yield indeterminate results during the window period. New algorithms employing NAAT as a confirmatory test are currently being evaluated.

    Figure 5 is a detailed diagram showing the days elapsed, from zero to 360, since the start of HIV infection. The diagram is divided into a sliding scale of four time periods:
