AIDS, HIV & STDs : How Early Can HIV Be Detected?

The timeframe between when a person contracts HIV and when tests can detect the infection is known as the window period. Everyones immune system is different. This makes it difficult to predict how long this stage will last.

Scientists have developed sensitive blood tests since the early days of the HIV epidemic. Its now possible to detect HIV antibodies, as well as other components of HIV, earlier than ever before. According to the Johns Hopkins Bloomberg School of Public Health, most people test positive within a few weeks of contracting HIV. For others, it may take

During the window period, a person may develop symptoms similar to the flu or other common viruses that include:

  • swollen lymph nodes
  • rash
  • fever

Symptoms may last from a few days to a few weeks. And they may range from mild to severe. But its possible to pass through the early infection stage without experiencing any symptoms at all. During this time, a person may not even realize that theyve contracted HIV.

How Often Do You Need To Get Tested For Hiv

How often you should get tested depends on your personal practices, risk behaviours, and how often you engage in them.

For most people, it is important to have a full sexual health test at least once each year. This testing includes:

  • HIV

Even if you always use condoms, it is recommended you get tested annually as condoms dont provide 100% protection against HIV and STIs.

Screening For Hiv In Pregnancy

If you’re pregnant, you’ll be offered a blood test to check if you have HIV as part of routine antenatal screening.

If untreated, HIV can be passed to your baby during pregnancy, birth or breastfeeding. Treatment in pregnancy greatly reduces the risk of passing HIV on to the baby.

When Do Symptoms Occur

Some people have flu-like symptoms within two to four weeks after infection, but others may not feel sick or not develop symptoms at all until later.

See a healthcare provider if you have symptoms of HIV and think you may have been exposed to HIV. Getting tested for HIV is the only way to know for sure.

In the United States, HIV is spread mainly through having anal or vaginal sex or sharing needles or syringes with an HIV-positive partner. Anal sex is the highest-risk behavior.

You can prevent HIV by using condoms correctly every time you have sex pre-exposure prophylaxis, a prevention method in which the HIV-negative partner takes daily HIV medicine to prevent HIV and treatment as prevention, a method in which the HIV-positive partner takes daily HIV medicine to achieve and maintain an undetectable viral load.

Only antigen/antibody tests or nucleic acid tests can diagnose acute HIV infection. NATs look for actual virus in the blood, and antigen/antibody tests look for HIV antibodies and antigens. Antibodies are produced by your immune system when youre exposed to viruses like HIV, and antigens are foreign substances that cause your immune system to activate.

However, no test can detect HIV immediately after infection. NATs can usually tell if you have an HIV infection 10 to 33 days after exposure, while antigen/antibody tests can tell 18 to 45 days after exposure.

  • Mouth ulcers or sores

Im Pregnant When Should I Test

HIV test in hindi

Testing for HIV during your pregnancy is very important. Left undiagnosed and untreated women living with HIV can pass the virus on to their unborn babies. In most countries, HIV tests are a routine part of the care women receive during pregnancy . Partners of pregnant women should also get tested during this time.

The earlier you test in your pregnancy the better. You’ll usually be tested in your first appointment, ideally before your tenth week. These tests should be repeated, either every three months or at least once again in your third trimester.

Your doctor will tell you everything you need to know about HIV testing alongside the other blood tests they do during pregnancy.

If you find out you are positive, youll be given treatment to prevent passing HIV on to your child. The earlier you start treatment, the greater the chance your child will be born HIV-negative. Check out our section on Pregnancy, childbirth & breastfeeding for more information.

How Soon Can I Get Tested For Stds After Unprotected Sex

  • Trichomoniasis Incubation Period
  • Lets say youve recently had unprotected sex and now youre worried that you may have picked up a sexually transmitted disease . With STD rates rising higher than ever before, this is a totally valid and legitimate concern. So what do you do? Getting tested would be a very smart decision, but you may be surprised to learn that you can actually test too early.

    If you feel like you could have contracted an STD, your instinct may be to get tested immediately, but this can be a huge mistake. Testing too early can cause inaccurate results, possibly leading you to believe youre STD-free when youre really not. This is because each STD has its own unique incubation period, which you must out wait in order to get accurate results. Like many things in life, timing is everything.

    What Is an STD Incubation Period?

    An incubation period is the span of time from when you first come in contact with an STD to when antibodies form to fight the STD1). Tests look for the presence of these antibodies during testing2), and if you do not wait until the incubation period has ended, you may not allow your body sufficient time to develop enough antibodies for it to show up in testing, causing a false-negative result.

    If you would like to test for gonorrhea, consider also testing for chlamydia as these two STDs frequently occur together. 4)

    Understand The The Window Period Before You Get Tested

    This is also known as Incubation Period. It measures the potential exposure of a person to the HIV virus and the point where tests for it give a positive result.

    Relying on symptoms for HIV detection surely increases the risk one poses to his/her life. After attacking someone, the virus takes almost 3 months to mature and give positive test result for itself. Rarely, it may take even more time. This duration i.e. time between the attack of the virus and final approval of it through the test is known as Window Period. Yet it is better to detect HIV even before the window period. It is done through a different type of test known as viral load test.

    This is the prime period of growth for the virus as the person may still be under the illusion of being unaffected by it. Although it might be spreading its wings down below! Its span is different on different people. An individual may give positive result after 9 days of virus contraction while some may show it after 40 days. However, the average incubation period ranges from 25 days to 2 months. It is, therefore, advisable to go for testing after the expiry of the incubation period.

    What Does A Positive Result Mean

    A follow-up test will be conducted. If the follow-up test is also positive, it means you are living with HIV .

    If you had a rapid screening test, the testing site will arrange a follow-up test to make sure the screening test result was correct. If your blood was tested in a lab, the lab will conduct a follow-up test on the same sample.

    It is important that you start medical care and begin HIV treatment as soon as you are diagnosed with HIV. Antiretroviral therapy or ART is recommended for all people with HIV, regardless of how long theyve had the virus or how healthy they are. ART works by lowering the amount of virus in your body to very low levels, called viral suppression. It slows the progression of HIV and helps protect your immune system. If you are on ART and virally suppressed, you can stay healthy for many years, and greatly reduce your chance of transmitting HIV to sex partners.

    If you have health insurance, your insurer is required to cover some medicines used to treat HIV. If you dont have health insurance, or youre unable to afford your co-pay or co-insurance amount, you may be eligible for government programs that can help through Medicaid, Medicare, the Ryan White HIV/AIDS Program, and community health centers. Your health care provider or local public health department can tell you where to get HIV treatment.

    How Is The Test Used

    How Early Can HIV Infection Be Detected

    HIV tests are used to screen for and diagnose HIV infections.

    Screening

    Different types of tests may be used for HIV screening:

  • Blood test for HIV antibody and HIV antigen this is the recommended screening test for HIV. The tests that use a blood sample drawn from a vein can detect HIV infections in most people approximately 2 to 6 weeks after infection, while fingerstick blood tests can detect HIV infections 2 to 12 weeks after infection. This combination test increases the likelihood that an infection is detected by testing for both HIV antigen and antibodies:
  • HIV antigen the level of p24 antigen and the amount of virus increase significantly soon after initial infection. Testing for p24 allows for detection of early infections, before HIV antibody is produced.
  • Antibodies to HIV-1 and HIV-2HIV-1 is the most common type found in the United States, while HIV-2 has a higher prevalence in parts of Africa. A few weeks after exposure to the virus, antibodies to HIV are produced in response to the infection and remain detectable in the blood thereafter, making the antibody test useful for detecting infections weeks after exposure.
  • HIV antibody testingall HIV antibody tests used in the U.S. detect HIV-1 and some tests can also detect HIV-2. These tests are available as blood tests or saliva tests. HIV antibody tests can detect infections in most people 3 to 12 weeks after infection.
  • Diagnosis

    Making Hiv Testing Routine

    Its recommended that you test for HIV and other sexually transmitted infections at least once a year if youre having sex, even if you always use protection.

    You might want to test more regularly than this, for example, if you are having sex with a new partner or feel you are more at risk. Groups who are more at risk are recommended to test more regularly. Testing every 3-6 months is often advised for men who have sex with men.

    Testing regularly helps keep your mind at rest, and if you test positive, it means you can start treatment quickly, protecting your health.

    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.

    If you think you might have been exposed to HIV, its best to speak to a healthcare professional immediately.

    Even if you dont think you have been at risk, testing regularly is good practice for people who are having sex. Its important to test for HIV during pregnancy. If you know your status, you can avoid passing the virus on to your baby. A window period is the amount of time it takes after infection for a test to give you an accurate result. Its good to know about window periods, but dont delay getting tested if you think you might have been exposed to HIV.

    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.

    Types Of Hiv Tests And Their Window Periods

    • Nucleic Acid Test A NAT can usually tell you if you have HIV infection 10 to 33 days after exposure
    • Antigen/Antibody TestAn antigen/antibody test performed by a laboratory on blood from a vein can usually detect HIV infection 18 to 45 days after exposure. Antigen/antibody tests done with blood from a finger prick take longer to detect HIV .
    • Antibody TestAn antibody test can take 23 to 90 days to detect HIV infection after an exposure. Most rapid tests and self-tests are antibody tests. In general, antibody tests that use blood from a vein detect HIV sooner after infection than tests done with blood from a finger prick or with oral fluid.

    Ask your health care provider or test counselor about the window period for the test youre taking and whether you will need a follow-up test to confirm the results. If youre using a self-test, you can get that information from the materials included in the tests package.

    If you get an HIV test after a potential HIV exposure and the result is negative, get tested again after the window period. Remember, you can only be sure you are HIV-negative if:.

    • Your most recent test is after the window period
    • You havent had a potential HIV exposure during the window period. If you do have an exposure, then you will need to be retested.

    How Soon Can Hiv Be Detected By A Blood Test

    The window period refers to the time between when a person is first exposed to HIV and when it will show up on different types of HIV tests.

    The window period can last anywhere from 10 days to 3 months, depending on your bodys immune response and the type of test that youre taking.

    During the window period, a person may test HIV-negative even though theyve contracted HIV.

    A person can still transmit HIV to others during this period. In fact, transmission may even be more likely because there are higher levels of the virus in a persons body during the window period.

    Here is a quick breakdown of different types of HIV tests and the window period for each.
