How Long To Wait For Hiv Test After Exposure

How Long Does It Take To See The Signs Of Hiv

Rapid HIV Test Accuracy 90 Days After Exposure

The signs and symptoms of HIV may first appear within two to four weeks of infection. The stage in which the symptoms appear is called the stage of acute HIV infection. The symptoms appear due to the resistance or fight of the immune system against HIV. In the initial stage, the virus multiplies rapidly and spreads throughout the body. It targets and destroys the CD4 cells . As a result, the level of HIV in the blood and the chances of transmission at this stage are very high. It is crucial to recognize the early signs and seek medical help, since early diagnosis and treatment of HIV gets the best results.

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.

How Often Should You Test For Hiv

Thirty years after first AIDS diagnosis, screening for HIV ...

Testing at least once a year for HIV and other sexually transmitted infections is good sexual health practice for everyone who is sexually active, even if you know you havent put yourself at risk of infection. Depending on how many different sexual partners you have in any one year, you might want to consider testing more regularly.

Gay, bisexual and other men who have sex with men should get tested routinely for HIV and other STIs at least annually or every three months if having sex without condoms with new or casual partners.

Black African men and women should have a regular HIV and STI screen if having sex without condoms with new or casual partners.

How Do You Know If You Need Pep

PEP may be right for you if you are HIV-negative or dont know your HIV status, and you think you may have been exposed to HIV in the last 72 hours:

  • During sex
  • Through shared needles, syringes, or other equipment used to inject drugs, or
  • Through sexual assault

Contact your health care provider immediately or go to an emergency room or urgent care clinic right away.

Your health care provider or emergency room doctor will evaluate you, help you decide whether PEP is right for you, and work with you to determine which medicines to take for PEP.

In addition, if you are a health care worker, you may be prescribed PEP after a possible exposure to HIV at work, such as from a needlestick injury.

How Soon After Exposure To Hiv Can Tests Detect I Have The Virus

The window of time between exposure to HIV and when a test will show you have the virus varies from person to person and by the type of test:

  • Nucleic acid test : The NAT test can detect HIV infection the earliest. It can tell if you have HIV infection 10 to 33 days after exposure.
  • Antigen/antibody test: The antigen/antibody test can detect infection 18 to 45 days after exposure when performed by a lab using blood from a vein. If the sample is from a finger prick, the window is 18 to 90 days after exposure.
  • Antibody test: Antibody tests can detect infection 23 to 90 days after exposure.

If your initial test is negative, get a second test after the window of time has passed. The second test can confirm your negative result in case you got tested before the infection was active in your body.

Remember, post-exposure prophylaxis can help prevent infection, but you must start it within 72 hours of possible infection. Talk to your healthcare provider about how to start PEP.

What Does A Negative Result Mean

If your HIV test result comes back negative it means that the test hasnt found signs of HIV infection.

However, if you have been at risk since your last test then youll need to test again. Also remember that most HIV tests can only detect HIV one to three months after exposure. If you were at risk more recently than this you will need to test again to be sure that your results are accurate.

Using a condom is the best way to protect yourself from HIV.

Be aware that testing negative for HIV doesnt mean that your partners are HIV-negative. HIV tests only apply to the person who took the test. If any of your previous or current partners are worried about HIV, encourage them to take a test.

What Are The Treatments For Hiv/aids

Currently, there is no cure for HIV infection or AIDS. However, there are therapies that can improve immune function, reduce the risk and/or frequency of opportunistic infections, and prolong life. The U.S. Department of Health and Human Services Panel on Antiretroviral Guidelines for Adults and Adolescents as well as the World Health Organization recommend that all individuals diagnosed with HIV infection receive treatment as soon as possible, including pregnant women. With advances in treatment, individuals with HIV infection are living longer, healthier lives. People typically take at least three drugs from two different classes in order to prevent or minimize virus replication and the emergence of drug-resistant strains. Combinations of three or more antiretroviral drugs are referred to as highly active antiretroviral therapy or HAART. Read the Treatment section of the article on HIV Infection and AIDS for additional details.

Letting Partners Know You Have Hiv

If you have just been diagnosed with HIV, it will likely be a difficult time. You might still be struggling to come to terms with diagnosis.

During this time, it is important to let any sexual or injecting partners know they may have been exposed to HIV as soon as you can, so they can be tested and offered PEP if appropriate.

You do not have to do this alone. Your doctor or the Department of Health and Human Services Partner Notification Officers can help you through this process and ensure your identity is not revealed.. Both groups can provide information, support, and guidance for people living with HIV.

When You Should Take An Hiv Test

What testing service you should use, and which type of test, depends on when you might have been exposed to HIV. Signs of HIV infection dont show up in the blood right away. It normally happens within four weeks of infection, but can be longer.

If you think you might have been exposed to HIV in the last 72 hours , its possible to take post-exposure prophylaxis to help stop an infection from happening.

If your risk was recent, then your test provider will probably advise you to take a test immediately, followed by a second one a few weeks later. The second test will pick up any infection the first one may have missed.

If your risk was in the last three months, make sure you tell the person testing you, as it may affect the type of test youre given.

A self test is not guaranteed to pick up an infection thats occurred in the previous three months. If you think youve been exposed in the last three months, you should get a test in person.

Very occasionally it can take up to three months for antibodies to appear in the blood, so an HIV negative result is only totally accurate if three months have passed between the test and the last time a risk was taken. However, a negative result four to eight weeks after taking a risk is a very good sign that HIV infection hasnt happened.

    If you have had unprotected sex, shared injecting equipment or think that you have been at risk some other way, then you should talk to your doctor or a healthcare professional as soon as possible.

    They will be able to talk to you about your situation and help you decide what to do next. If you visit a healthcare professional within 72 hours of when you think you were exposed to HIV, you may be offered PEP . This is a course of emergency HIV treatment that can prevent HIV infection. It must be started within 72 hours and be taken properly.

    Unfortunately, PEP isnt always available and healthcare providers may only give it to you if they feel youre at a high risk of HIV. If you take PEP youll need to test before and after to ensure it has worked.

    If the time to take PEP has passed, then most modern HIV tests are now able to detect HIV from around four weeks after exposure. Depending on the type of test you are offered and when your risk was, your doctor may ask you to come back for further tests and a follow-up to check your results.

    If you think you have been exposed to HIV, it is in this early stage of infection that you are most likely to pass HIV on to others. Be extra careful during this time use condoms and dont share injecting equipment.

    It has almost been eight months since I was diagnosed with HIV. I was confused, ashamed, I kept asking, ‘How this could be?’. Slowly but surely Im beginning to accept that HIV is going to be a part of me and I definitely have control over it.

    What Is Being Tested

    Human immunodeficiency virus is the cause of AIDS . HIV screening tests detect the HIV antigen and/or HIV antibodies produced in response to an HIV infection in the blood. Some tests detect HIV antibody in oral fluid.

    When a person becomes infected with HIV, through exposure to the blood or body fluids of an infected individual or a contaminated needle, for example, the virus begins to replicate itself, producing a large number of copies. During the first few weeks of infection, the amount of virus and the p24 antigen level in the blood can be quite high.

    About 2-8 weeks after exposure to the virus, the immune system responds by producing antibodies directed against the virus that can be detected in the blood. As the initial infection resolves and the level of HIV antibody increases, both virus and p24 antigen levels decrease in the blood.

    An HIV infection may initially cause no symptoms or cause flu-like symptoms that resolve after a week or two. The only way to determine whether a person has been infected is through HIV testing.

    If HIV is not detected early and treated, it may become a simmering infection that may cause few symptoms for a decade or more. If the infection is still not treated, eventually symptoms of AIDS emerge and begin to progressively worsen. Over time and without treatment, HIV destroys the immune system and leaves a person’s body vulnerable to debilitating infections.

    Detecting and diagnosing HIV early in the course of infection is important because:
