How Long Until You Test Positive For Hiv

Hiv Tests For Screening And Diagnosis

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

HIV tests are very accurate, but no test can detect the virus immediately after infection. How soon a test can detect HIV depends on the type of test being used. There are three types of HIV tests: antibody tests, antigen/antibody tests, and nucleic acid 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 or self-test and it is positive, the person should go to a health care provider to get follow-up testing. If the initial HIV test is a lab test and it is positive, the lab will usually conduct follow-up testing on the same blood sample as the initial test. Although HIV tests are generally accurate, follow-up tests allow the health care provider to confirm the result.

Which Test Can Give Me Results The Soonest

The period of time also differs, depending on which kind of test you take. The different types of tests include:

  • Antibody tests, which look for the antibodies special proteins that help fight infection that your body makes in reaction to an HIV infection. Most rapid tests and at-home tests are these kind. Antibody tests require the longest wait time after infection to get an accurate result. For most people around 97% this takes anywhere from 2 to 12 weeks. For some, it can take as long as 6 months.
  • Combination or fourth-generation tests, which look for both antibodies and antigens. Antigens are part of the virus itself. One antigen, p24, is detectable before your body starts making antibodies. These tests are becoming more common in the U.S. They can tell you if you have HIV a little sooner than an antibody test can.
  • Nucleic acid tests , which can detect HIV in your body the soonest after infection. The test looks for the virus in your blood. You need a certain amount of the virus in your blood before the test will detect it. This is called your viral load. You can get a negative test if your viral load is still low. A NAT can tell you if you have HIV as early as 7 to 28 days after infection. It gives the quickest result, but itâs also the most expensive. Doctors donât typically use it unless youâre at a high risk of exposure to HIV.

Youâre more likely to have a NAT if you:

False Positives Vs False Negatives

France begins selling HIV self

Because STI tests arent perfect, people who design them often have to choose whether its better to have more false-positive or more false-negative results. Which is better depends on the severity of the disease and the healthcare providers ability to treat it.

Imagine, for example, that a condition has no serious long-term consequences but the treatment itself is grueling. In such cases, a false positive is worse than a false negative because it may expose a person to needless treatments that cause more harm than good.

On the other hand, if an infection is serious and requires immediate treatment, the test would need to be highly sensitive to avoid a false-negative result. Doing so can lead to a missed diagnosis. One such example is an HIV test.

Get Tested Regularly If You Are At Greater Risk Of Hiv

If you are at greater risk of HIV get tested regularly.

Gay, bisexual, trans and other men who have sex with men should get tested every 3 months . This may vary depending on how many sexual partners you have during the year.

Talk with your doctor or sexual health specialist for advice. They can also provide information about how to reduce your risk for HIV and other STIs.

What Does Hiv Do To A Person

HIV infects white blood cells of your immune system called CD4 cells, or helper T cells. It destroys CD4 cells, causing your white blood cell count to drop. This leaves you with an immune system that cant fight off infections, even those that wouldnt normally make you sick.

HIV initially makes you feel sick with flu-like symptoms. Then it can hide in your body for a long time without causing noticeable symptoms. During that time, it slowly destroys your T-cells. When your T-cells get very low or you begin to get certain illnesses that people with healthy immune systems dont get, HIV has progressed to AIDS.

AIDS can cause rapid weight loss, extreme tiredness, mouth or genital ulcers, fevers, night sweats and skin discolorations. Other illnesses and cancers often happen in people living with AIDS and can cause additional symptoms.

Whats a retrovirus?

A retrovirus is a virus that works backward from the way human cells do. Human cells have instructions that send a message to make building blocks for your body .

Retroviruses have their instructions written on RNA. When a retrovirus invades your cells, it changes its RNA to look like your cells instructions . Then it cuts your cells DNA and inserts its instructions into them. Your cell then acts as though the virus instructions are its own.

In some cases, it might be appropriate to get tested more than once. You may be advised to take an early test, and then a second test over 45 days later after the potential exposure.

An early test may show a positive or a negative result, and require confirmation from a second.

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.

What Tests Diagnose Hiv

There are three types of HIV tests: antigen/antibody tests, antibody tests and nucleic acid tests :

Antigen/antibody tests

Antigen tests look for markers on the surface of HIV called p24. Antibody tests look for chemicals your body makes when it reacts to those markers. HIV antigen/antibody tests look for both.

A healthcare provider will take a small sample of blood from your arm with a needle. The blood is sent to a lab and tested for p24 and antibodies to it. An antigen/antibody test is usually able to detect HIV in 18 to 45 days after exposure.

A rapid antigen/antibody test may also be done with a finger prick to draw blood. Youll need to wait at least 18 days after exposure for this type of test to be able to detect HIV. You may need to take the test up to 90 days after exposure for accurate results.

Antibody tests

These tests look for antibodies to HIV in your blood or saliva. This can be done with a blood draw from your arm, a finger prick or with a stick that you rub on your gums to collect saliva.

An antibody test can take 23 to 90 days after exposure to detect HIV. Antibody tests done with a blood draw can detect HIV sooner than those done with saliva or blood from a finger prick.

Nucleic acid tests

NATs look for the HIV virus in your blood. A healthcare provider will take a small sample of blood from your arm with a needle. The blood then is sent to a lab and tested for HIV.

What Can I Expect If I Have Hiv

If youre diagnosed with HIV, its important to know that those living with HIV who follow treatment guidelines can live full lives for nearly as long as those without HIV.

If you have a high CD4 count and an undetectable viral load within a year of starting treatment, research suggests youll have the best outcomes, as long as you continue your treatment plan.

You can improve your outlook by:

  • Getting tested as part of routine healthcare or if you think youve been exposed.
  • Starting ART soon after being diagnosed.
  • Taking your medicine every day.
  • Keeping your appointments with your healthcare team.

ART can keep blood levels undetectable but cant entirely rid your body of the virus . If you dont take your medication every day, the virus can start multiplying again and mutate, which may cause your medications to stop working.

Left untreated, it can take about 10 years for HIV to advance to AIDS. If you progress to AIDS and it goes untreated, you can expect to live about three years more.

For those on treatment, if you have a high CD4 count and undetectable viral load within a year of starting treatment, you can expect to live about as long as someone without HIV. If you have a low CD4 count or a detectable viral load within a year of starting treatment, you may live 10 to 20 years less than someone without HIV.

What Happens If I Test Positive

How I Discovered I was HIV Positive

If the result from an initial HIV test is positive, a healthcare professional will order follow-up testing to learn if the result is accurate.

If the first test was conducted at home, a healthcare professional will draw a sample of blood to test in a lab. If the first test was done in a lab, follow-up testing may be conducted on the same blood sample at the lab.

If the second test result is positive, a healthcare professional can help explain the treatment options for HIV. Early diagnosis and treatment can help improve the long-term outlook and reduce the chances of developing complications from HIV.
