How Do The Tests Work
Most HIV tests use a blood sample, either from a blood draw or finger prick. Others use saliva , but this is a little less accurate than blood tests.
Some HIV tests look for the virus itself. But most look for the antibodies for HIV. Antibodies are part of the immune system and fight infections. When someone is infected with HIV, the body creates antibodies to fight HIV.
Testing results may be available that day or can take longer come back.
What Do The Results Mean
If your result is negative, it can mean you donât have HIV. A negative result may also mean you have HIV but itâs too soon to tell. It can take a few weeks for HIV antibodies and antigens to show up in your body. If your result is negative, your health care provider may order additional HIV tests at a later date.
If your result is positive, you will get a follow-up test to confirm the diagnosis. If both tests are positive, it means you have HIV. It does not mean you have AIDS. While there is no cure for HIV, the disease can be effectively controlled with medicine. The medicine used to treat HIV is called antiretroviral therapy . ART can significantly reduce the amount of HIV in the blood. People with HIV who take ART before the disease gets too advanced can live long, healthy lives. If you are living with HIV, itâs important to see your health care provider regularly.
What Support Is Available
If you receive an HIV diagnosis, you can find help. Your healthcare provider can recommend support groups and counselors.
If someone tells you they are HIV-positive, they are telling you because they trust you. The time right after diagnosis can be very tough. You can support them in many ways:
- Be a friend. While they may not be ready to talk about their diagnosis right away, show them you care by treating them as you did before.
- Listen. Your friend may just need someone to listen to their concerns and fears. Be there for them.
- Learn about the disease. The reference section of this article has additional information to learn about the condition.
- Encourage them to seek treatment. Your friend may not realize they have options available. They do, and they can get treatment. Help them find it and stick to it.
- Get help for yourself. While it will be a challenging time for your friend, you may need some support too. Talk to others a counselor, for example about any concerns or anxieties you may have.

Who Should Get Tested For Hiv
Roughly one in seven Americans who have HIV dont know they do. The U.S. Centers for Disease Control recommends that everyone between the ages of 13 and 65 get tested at least once. If you are in a higher risk group, you should consider more frequent testing.
Even if you tested negative, you should get tested if you can answer yes to any of these questions about your activity since that test. Have you:
- Had sex with another man ?
- Had anal or vaginal sex with someone who is HIV-positive?
- Had more than one sex partner?
- Injected drugs with a shared needle?
- Received another STI diagnosis?
- Had sex with someone who could answer yes to any of these questions?
If you believe you may have had HIV exposure within the last 72 hours, talk to your healthcare provider. You may be able to get post-exposure prophylaxis — ie, medication. A PEP can prevent HIV when administered correctly. The sooner you begin to take it, the better, although it isnt 100% effective.
How An Hiv Test Works
An HIV test is a blood test. It does not detect HIV itself, but looks for a protein found in an HIV cell, or an antibody made by the body to fight HIV.
HIV tests in the UK are very reliable. They can occasionally produce a positive result which is then found to be negative when tested again. This is called a false positive and is rare, occurring in less than 1 in 1000 cases.

Depending on the pregnancy kit used, its possible you could detect pregnancy few days before your next period. Some pregnancy kit can detect pregnancy as early as five days before your period.
Though this is not 100 percent accurate, it may ease anxiety in women who are trying to conceive.
If you test positive before your next period, its more likely you have a baby coming. On the other hand, a negative pregnancy test after sex is likely not accurate.

How Soon Can I Take An Hiv Test
This question usually refers to how soon after exposure can someone test for HIV.
This used to involve waiting 3 to 4 weeks before taking an HIV test .
However, 2020 UK guidelines now recommend waiting 6 weeks.
This is because 4th generation HIV tests will detect 99% of infections at 6 weeks compared to 95% of infections 4 weeks after exposure.
A negative test after four weeks needs to be confirmed with a second test three months after the risk. This is to cover the small chance that you take longer than four weeks to generate an antibody response.
Extending this to 6 weeks means the confirmatory test is no longer needed.
In high risk exposures, especially if symptoms occur, viral load testing is sometimes used after one week. This includes after a sexual assault or after a needlestick injury to a healthcare worker.
In these cases a viral load test can exclude an infection when there are symptoms.
Viral load tests are not approved to diagnose HIV. A negative result still needs to be confirmed by an antibody test three months after the risk.

Benefits Of Early Detection And Treatment
If you think you may have an STD, its important to stop engaging in sexual activity and seek treatment. Early detection and treatment of STDs plays an important role in stopping the transmission of STDs between yourself, your sexual partners, and their sexual partners. In some cases, it can even save your life.
Some of the potential risks of untreated STDs include:
- pregnancy and birth-related risks, from untreated bacterial STDs, HIV, and hepatitis B
- organ damage, dementia, paralysis, or death, from untreated syphilis
Taking care of your sexual health is important. Not everyone will voluntarily disclose their STD status to you. You can take control of your sexual health by asking questions, screening new sexual partners, and having open and honest discussions about sexually transmitted diseases.
