The 4th generation HIV test has the capability to detect HIV earlier than previous testing protocols as it detects p24 antigens. The identification of p24 antigens in the blood indicates the actual presence of certain HIV virus proteins. This is direct evidence that the blood contains the HIV virus. 4th generation testing detects HIV as soon as two to three weeks after exposure.4th generation HIV test accuracy
How to get tested for HIV/AIDS?
Blood tests are the most common way to diagnose HIV, the virus that causes AIDS. These tests look for antibodies to the virus that are present in the blood of infected individuals. People exposed to the virus should get tested immediately. Because it can take from 4 weeks to 12 weeks to develop antibodies to the virus, follow-up tests may be needed.
What is the screening test for HIV?
These are tests that check if you’ve been infected with HIV. The most common tests are the antibody test, Antigen test, and Antibody-antigen test. If the screening test is positive, a follow-up/confirmatory test is done.
When to check for HIV or when to get tested for HIV?
If you have had unprotected sex, shared injecting equipment, or think that you have been at risk some other way, it’s best to get tested immediately or contact a healthcare professional for further guidance. It’s important to test for HIV during pregnancy to know your status and avoid passing the virus on to your baby.
p24 antigen and antibody test
Also known as the Fourth-generation HIV test, can detect both HIV antibodies and p24 antigens in blood. It is extremely accurate and can reliably detect HIV as soon as 1 month after a person contracts it.
p24 antigen HIV test window period
p24 test is generally only positive from about two to three weeks after infection with HIV. The p24 protein cannot be detected until about a week after infection with HIV because it generally takes that long for the virus to become established and multiply to sufficient numbers that they can be detected.
Had unprotected sex what to do?
Whether you’ve noticed symptoms or not, you should get an STI test after two weeks after having unprotected sex. HIV tests should also be done based on the window period. For the majority of people, HIV testing will be accurate at four to six weeks after possible infection.
HIV RNA early detection test
HIV RNA or fourth-generation HIV test is the most accurate test and can detect HIV as early as 14 days following transmission by detecting the HIV p24 antigen. HIV RNA viral load can be performed if an acute infection is suspected.
HIV 1 and HIV 2 antibody test
An HIV antibody test can determine if you have HIV from 3–12 weeks after infection. That’s because it can take a few weeks or longer for your immune system to make antibodies to HIV.
4th generation HIV test window period
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 2–6 weeks of infection. The HIV antibody/antigen test is one of the most common types of HIV tests.

If you’ve had unprotected sex, it’s a good idea to get tested. Here’s how long after exposure we can get a reliable test result:
- 2 weeks: gonorrhea and chlamydia
- 1 week to 3 months: syphilis
- 6 weeks to 3 months: HIV, hepatitis C, and B
