How Long Does Hiv Screening Take

Will My Partner Have The Same Results As Me

Real Question: How Long Does it Take to Test Positive for HIV?

Dont assume that if you are positive, or negative, your partner will have the same result. It may be that your partner has a different test result to you. This is why its a good idea to encourage your partner to get tested too, whether your results are positive or negative. If youre worried about telling your partner that you are positive or asking them to take a test, speak to your healthcare advisor. They can often help you with ways to do this.

What Is Acute Hiv Infection

There are three stages of HIV infection:

  • Stage 1:Acute HIVinfection
  • Stage 2:Chronic HIV infection
  • Stage 3:AIDS

Acute HIV infection is the first stage of the infection. Usually within two to four weeks of infection, two-thirds of those with HIV will experience flu-like symptoms. These symptoms may last for several days or even weeks. However, some people may experience no symptoms at all.

In this stage, there is a large amount of HIV in your blood, which is known as the viral load. Studies have noted incredibly high viral loads during the acute stage, meaning you are more contagious at this time.

What Happens During An Hiv Test

You will either get a blood test in a lab, or do your own test at home.

For a blood test in a lab:

  • A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

For at home test, you will need to get a sample of saliva from your mouth or a drop of blood from your fingertip.

  • The test kit will provide instructions on how to get your sample, package it, and send it to a lab.
  • For a saliva test, you will use special spatula-like tool to take a swab from your mouth.
  • For a fingertip antibody blood test, you will use a special tool to prick your finger and collect a sample of blood.

For more information on at-home testing, talk to your health care provider.

Introduction And Guiding Principles

A request was made by the Federal/Provincial/Territorial Committee on AIDS for the Public Health Agency of Canada to develop guidelines on HIV testing that reflect the realities facing care providers and their clients, as well as advances in HIV testing policy and practice. To inform the development of this guide, the Agency commissioned a literature review and consultations with key stakeholders, including people living with HIV/AIDS and other affected populations, academics, nurses, physicians, professional associations, non-governmental organizations, policy-makers, community workers, and legal and ethical experts. As a result, the recommendations outlined in the guide are based on the most up-to-date evidence and expert opinion.

Hiv Tests For Screening And Diagnosis

How do HIV tests work and what

HIV tests are very accurate, but no test can detect the virus immediately after infection. How soon a test can detect HIV depends upon different factors, including the type of test being used. There are three types of HIV diagnostic tests: nucleic acid tests , antigen/antibody tests, and antibody tests.

An initial HIV test usually will either be an antigen/antibody test or an antibody test. If the initial HIV test is a rapid test or a self-test and it is positive, the individual should go to a health care provider to get follow-up testing. If the initial HIV test is a laboratory test and it is positive, the laboratory will usually conduct follow-up testing on the same blood sample as the initial test. Although HIV tests are generally very accurate, follow-up testing allows the health care provider to be sure the diagnosis is right.

Resources for FDA-approved laboratory tests, self-tests, and testing of self-collected samples are available. Learn more about testing in nonclinical settings and screening in clinical settings.

Testing of pregnant women in labour with no prenatal work up and a high risk for HIV.STAT testing should only be requested when it directly affects patient care in an emergency medical circumstance. STAT samples must be shipped separately from routine specimens in a clearly marked package indicating STAT and handled in accordance with the Canadian Biosafety Standards and shipped in accordance with the Transportation of Dangerous Goods Regulations. Failure to ship separately will delay testing.Notify PHO immediately when a STAT sample is sent by contacting our Customer Service Centre at 416-235-6556 / 1-877-604-4567. After-hours STAT testing requires approval by a PHO Microbiologist who can be contacted through the Customer Service Centre.

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.

Where To Access Testing Services

Standard HIV testing can generally be accessed through any health provider across the country. Each province is responsible for licensing the laboratories that provide HIV screening and confirmatory testing in its jurisdiction. In general, all provincial Public Health Laboratories provide both screening and confirmatory testing. Reference and specialized services, when required, are provided by the National HIV Reference Serology Laboratory after consultation with the provincial laboratory. It is advisable to contact your testing laboratory to confirm the specimen collection details.

Anonymous or POC testing locations can be found by calling a local HIV/AIDS hotline .

Who Should Be Tested For Hiv And How Frequently

How long can HIV go undetected with testing | HIV/AIDS

It is recommended that the consideration of HIV testing be made a component of routine care. In general, care providers should take an active approach to HIV testing, offering HIV testing to clients whether or not clients have asked for a test. In the provision of routine medical care, and in discussion with the client, care providers should consider whether there is a benefit to an HIV test.

HIV testing is associated with several advantages:

  • a negative test result is an opportunity for clients to take an active role in remaining HIV negative
  • the early detection of HIV, especially at the acute stage, can improve outcomes for individuals and prevent further transmission of HIV
  • detection at any stage of the disease, prior to wasting and dementia, is an opportunity to initiate lifesaving treatment and other related healthcare services
  • opportunities arise for conversations with clients about risk-reduction strategies

2.1.1 Testing recommendations

An in-depth comprehensive HIV behavioural risk assessment is not a requirement for offering an HIV test. An assessment that the client understands how HIV is transmitted, the implications of testing , and how to interpret the test results is sufficient.

For occasions when clients may not be able to accurately estimate their risk, the guide includes more detailed guidance in Appendix B for conducting rapid risk assessments and a more detailed technical review of HIV transmission risks can be found in Appendix C.

Who Should Get An Hiv Test

The CDC recommends that everyone in the United States between the ages of 13 and 64 get tested for HIV at least once.

You should be tested more often — at least once a year — if youâre at higher risk of getting HIV, including if you:

  • Have had several sexual partners
  • Had unprotected sex with someone who is or could be HIV-positive, including someone whose sexual history you don’t know
  • Injected drugs with a needle, syringe, or other device that someone else used first
  • Have had or are getting tested for tuberculosis, hepatitis, or any sexually transmitted disease, including syphilis, gonorrhea, chlamydia, or herpes
  • Have had sex for drugs or money
  • Had sex with someone who has a history of any of these

What About False Results

Some HIV tests have a very slight chance of giving you false results. A âfalse-positiveâ result means your test shows you have HIV when you donât. Tests may also give you a âfalse-negativeâ result. That means the test says you donât have HIV, but you do.

The rapid oral fluid test is more likely to give you a false-positive result than other tests. If you take a rapid oral test and get a positive result, the doctor will give you a blood test to confirm your diagnosis.

The HIV RNA or viral load test is not generally used to diagnose HIV. If you have this test done and get a positive result, the doctor may start you on HIV treatment, but you should always take an antibody test a few months later to confirm your diagnosis.

If you test positive: These tests are all screening tests for HIV. That means that if you take an HIV test and get a positive or even an unclear result, youâll need another blood test to confirm that you do or donât have the virus. The results of both tests together are more than 99% accurate. The tests used to confirm HIV infection are either the Western blot or indirect fluorescent antibody test. If your screening test went to a laboratory, they can do this additional testing on the same blood sample. But if you were tested in a community clinic or at home, youâll need to give an additional blood sample for follow-up.

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:

THE IMPORTANCE OF TESTING

Sex without the use of an effective HIV prevention tool or sharing injecting equipment are all activities that can put you at risk of HIV by allowing bodily fluids or vaginal fluid) to enter your body, and possibly your bloodstream.

The only way to know your HIV status is through testing. Testing for HIV is important because it enables the individual to know their status, seek treatment and support if necessary and take steps to prevent onward transmission.

Being tested regularly for HIV is simple, quick and made convenient with multiple testing sites in major cities and towns across Australia. Testing is also available through general practitioners.

There are also a number of community-based testing services around the country, including those that are led by peers.

REGULARITY IS KEY

Gay men and other men who have sex with men are recommended to have a comprehensive sexual health check at least twice a year, and up to four times a year if they are in one or more of these categories:

  • have had any condomless anal sex
  • have more than 10 sexual partners in 6 months
  • participate in group sex
  • use crystal meth.

UNDERSTANDING HIV RAPID TESTING

Traditional HIV testing, where blood is drawn and sent to the laboratory for testing can take several days or more to get a result. Rapid Testing uses a pinprick of the finger and returns results within 10 to 20 minutes.

What Is An Hiv Test

An HIV test shows whether you are infected with HIV . HIV is a virus that attacks and destroys cells in the immune system. These cells protect your body against disease-causing germs, such as bacteria and viruses. If you lose too many immune cells, your body will have trouble fighting off infections and other diseases.

There are three main types of HIV tests:

  • Antibody Test. This test looks for HIV antibodies in your blood or saliva. Your immune system makes antibodies when you are exposed to bacteria or viruses, like HIV. An HIV antibody test can determine if you have HIV from 312 weeks after infection. That’s because it can take a few weeks or longer for your immune system to make antibodies to HIV. You may be able to do an HIV antibody test in the privacy of your home. Ask your health care provider about at-home HIV test kits.
  • HIV Antibody/Antigen Test. This test looks for HIV antibodies and antigens in the blood. An antigen is a part of a virus that triggers an immune response. If you’ve been exposed to HIV, antigens will show up in your blood before HIV antibodies are made. This test can usually find HIV within 26 weeks of infection. The HIV antibody/antigen test is one of the most common types of HIV tests.
  • HIV Viral Load. This test measures the amount of the HIV virus in the blood. It can find HIV faster than antibody and antibody/antigen tests, but it is very expensive. It is mostly used for monitoring HIV infections.

Clinical Indications For Hiv Testing

Individuals requesting an HIV test.

Individuals with symptoms and signs of HIV infection.

Individuals with illnesses associated with a weakened immune system or a diagnosis of tuberculosis.

Unprotected anal or vaginal intercourse or use of shared drug equipment with a partner whose HIV status is known to be positive.

Pregnant or planning a pregnancy and their partners as appropriate.

Victims of sexual assault.

When To Get Tested

Seek medical advice immediately if you think there’s a chance you could have HIV. The earlier it’s diagnosed, the earlier you can start treatment and avoid becoming seriously ill.

Some HIV tests may need to be repeated 1-3 months after exposure to HIV infection, but you should not wait this long to seek help.

A GP or a sexual health professional can talk to you about having a test and discuss whether you should take emergency HIV medicine.

Anti-HIV medicine called post-exposure prophylaxis may stop you becoming infected if taken within 72 hours of being exposed to the virus.

What Are The Types Of Hiv Tests

Currently there are two ways to test for HIV. One of these is a standard laboratory test done using a blood sample taken from your arm. The result is available in 1 to 2 weeks.

The second type of HIV test is a called a point-of-care test using a drop of blood taken from your finger. The result is available at the time of testing. When a point-of-care test indicates that HIV antibodies may be present, a standard laboratory test is required to confirm HIV infection.

What Types Of Tests Diagnose Hiv

To diagnose HIV, healthcare providers can order any of three tests:

  • Nucleic acid test: The NAT test looks for the virus in your blood. It is a thorough laboratory test but can be costly. The results can take several days to receive.
  • Antigen/antibody test: This test looks for antibodies and antigens to HIV in your blood. Your immune system forms antibodies when it comes in contact with viruses, such as HIV. Antigens, however, are foreign substances that activate your immune system. HIV has a particular antigen that this test can find. This rapid test uses a drop of blood from a finger prick and can give you results in roughly 30 minutes.
  • HIV antibody test: This test is similar to the antigen/antibody test, but it only looks for the antibody. Just like the antigen/antibody test, this test produces results in around 30 minutes. It uses either a drop of blood from a finger prick or a swab of saliva.

Some states allow for home testing. There are two types of home tests:

  • Rapid self-test: The only rapid self-test available in the United States uses a saliva sample to check for infection. After you receive your kit, you swab your gums and use the test kit to get results.
  • Mail-in self-test: This test uses a blood sample from a simple finger prick. All of the supplies are in the kit to help you take the sample, package it and send it to the lab. A healthcare provider will tell you the results.
