The Healthcare Worker There To Help You
Before you test, your healthcare worker will talk to you about your sexual health and why youve decided to test. This is to help them understand your situation so they can offer you the best services and advice.
Remember, the healthcare professional is not there to judge you. There will be nothing you can say that they havent heard before so be honest with them, and ask as many questions as you want. Thats what theyre there for.
You should never feel pressured to test. The results will be completely confidential but you should only go through with it if you want to.
What Is It Used For
An HIV test is used to find out if you have been infected with HIV. HIV is the virus that causes AIDS . Most people with HIV don’t have AIDS. People with AIDS have an extremely low number of immune cells and are at risk for life-threatening illnesses, including dangerous infections, a severe type of pneumonia, and certain cancers, including Kaposi sarcoma.
If HIV is found early, you can get medicines to protect your immune system. HIV medicines may prevent you from getting AIDS.
Why Do I Need An Hiv Test
The Centers for Disease Control and Prevention recommends that everyone between the ages of 13 and 64 get tested for HIV at least once as part of routine health care. You may also need an HIV test if you are at higher risk for infection. HIV is mainly spread through sexual contact and blood, so you may be at a higher risk for HIV if you:
- Are a man that has had sex with another man
- Have had sex with an HIV-infected partner
- Have had multiple sex partners
- Have injected drugs, such as heroin, or shared drug needles with someone else
HIV can spread from mother to child during birth and through breast milk, so if you are pregnant your doctor may order an HIV test. There are medicines you can take during pregnancy and delivery to greatly reduce your risk of spreading the disease to your baby.

Can I Take The Test At Home
At-home HIV tests are a convenient way to take an HIV test in a private location. Testing for HIV at home is a form of HIV screening that requires additional follow-up if preliminary results are positive. At-home HIV tests can be obtained online, at a pharmacy, or at health departments and community-based organizations.
What Do The Results Mean
If your result is negative, it can mean you don’t have HIV. A negative result may also mean you have HIV but it’s 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, it’s important to see your health care provider regularly.

Hiv 1/2 Antibody Test Kit
HIV 1/2 Antibody Test Kit is intended for qualitative detection of HIV 1/2 antibody in human serum or plasma, applying to auxiliary diagnosis of HIV infection.
This product is used for in vitro qualitative detection of human immunodeficiency virus type 1 and type 2 antibodies in human serum or plasma samples. Human immunodeficiency virus is the causative agent of AIDS, mainly transmitted through blood transfusion or sexual contact. It is highly contagious and susceptible to all kinds of people. After the HIV invades the human body, it destroys the bodys immune system, causing the infected person to lose immunity gradually, and eventually leads to death. HIV is divided into two subtypes, HIV1 and HIV2. After the human body is infected with the virus, the corresponding antibodies generally appear within 1 to 3 months. Detection of HIV antibodies in the blood can effectively determine HIV infection and is the most effective detection method.
Sample type: Serum/plasma
How Is It Used
HIV antibody and HIV antigen testing is used to screen for and diagnose HIV infections. Early detection and treatment of HIV infection and immune system monitoring can greatly improve long-term health and survival. Also, if a person knows his or her HIV status, it may help change behaviors that can put him or her and others at risk.
Different types of tests may be used for HIV screening:
There are a few different ways a person can get access to HIV screening:

What Is The Window Period And What Is The Window Period For The Insti Rapid Hiv Test
After exposure to HIV, it can take from 3 to 12 weeks for an infected persons body to make enough antibodies for a screening test to detect them. This is called the window period. IgM antibodies are the first antibodies to be detected by INSTI and are typically present in the bloodstream approximately 3 weeks after infection. An individual may test positive with the INSTI Test in as little as 21-22 days after infection, however depending on the person it can take as long as 3 months for them to produce sufficient antibodies to generate a positive result. Approximately 97% of people will develop detectable antibodies during this window period.A negative result may not be accurate until 3 months after a possible exposure. If someone has been exposed to HIV and obtains a negative test result during the window period, they should re-test 3 months after possible exposure to HIV.
Where Can People Find Free Hiv Testing Locations
The CDC maintains a list of HIV testing locations for people who want to find out whether they have contracted the virus. This National HIV and STD Testing Resource can be accessed at . This site includes the ability to search for free testing locations as well as locations that provide rapid tests. Some clinics only provide HIV testing. However, sexually transmitted diseases clinics routinely provide HIV testing along with testing for diseases like chlamydia, gonorrhea, syphilis, and herpes.

What Is Hiv 1 And 2 Antibody
This test is done to confirm the HIV-1 and HIV-2 antibodies present in the blood. It also helps in differentiating HIV-1 and HIV-2 antibodies in specimens of serum which show reactive results with third and fourth generation HIV serologic assays. This test is not a screening test to detect HIV infection.

More Information About Hiv Antibody Testing
Does the HIV Antibody Test use a blood or urine sample?
Our HIV Antibody Test involves a small blood sample. There is no undressing or uncomfortable swabbing.
What do I need to do to prepare for the test?
No fasting or additional preparation is needed for the HIV Antibody blood test.
When is the right time to get the HIV Antibody Test?
The right time to take our 4th Generation HIV Antibody / Antigen Test is 2-3 weeks after exposure. Our blood testsearches for the presence of these antibodies in the blood, as well as antigens on the surface of the HIV virus.Most people will develop detectable antibodies withinthis time frame, but in rare cases it may take up to 3 months for them to develop. This test is sensitive to P24antigens, so it is useful for diagnosing HIV infections when antibody levels are still initially low. We dorecommend retesting after three months have past since potential exposure for conclusive results. If antibodies orantigens to HIV are found, a supplemental differentiation assay is performed at no additional cost to confirm thepresence of HIV. If you are concerned about recent exposure, our HIV RNAEarly Detection Test can detect the presence of HIV as early as 9-11 days after exposure.

Study Shows That Some Tests Fall Short In Early Infection
As the United States aims to increase early diagnosis and treatment of people with HIV, a greater focus has been placed on determining the accuracy of HIV tests in real-world settingsnot only to minimize the number of false positive or negative;test results but to better identify people during the early stages of infection when the risk of transmission is especially high.
In order to do this, researchers from the University of California, San Francisco conducted a review of over 21,000 HIV tests performed between the years 2003 and 2008 in some of the city’s high prevalence populations.
Of four types of tests used during this periodfrom first generation antibody tests to rapid oral tests761 people were diagnosed with HIV , while 58 were identified during acute infection.
The study also aimed to compare the accuracy of newer testing assaysincluding 4th generation antigen/antibody testsby retesting the blood from the 58 people previously diagnosed with acute;HIV infection.
The accuracy was measured both in terms of sensitivity and specificity .

What Is The 4th Generation Hiv Test
The fourth generation HIV test, also called an enzyme-linked immunosorbent assay test, is a more complete screening that can identify acute HIV. This is the time when the virus is multiplying rapidly and youre more likely to pass the infection.
In the first few weeks after exposure to HIV, your body produces an antigen known as p24. This protein is only present in people who have acute HIV infection. It triggers your immune system to respond.
The fourth generation tests can identify both HIV-specific antigen p24 and HIV antibodies with a blood sample.
The fourth generation tests require a blood sample thats sent to a lab for testing. Blood testing done by a lab is the most accurate type of test.
There are many products approved for fourth generation testing, including:
- ADVIA Centaur HIV Ag/Ab Combo Assay
- Elecsys HIV Combi PT
- Genscreen ULTRA HIV Ag-Ab
- VITROS HIV Combo Test
The healthcare clinic or doctors office you visit for an HIV test can tell you more about the exact test they use.
tests that can test for the presence of HIV. HIV testing can be done by drawing blood from a vein, a finger stick, or taking an oral swab of fluid.
Tests can measure antibodies, antigen/antibody , and theres also a nucleic acid test . The NAT test can identify HIV and viral load . It can tell if you have HIV within around 10 to 33 days of exposure.
Older tests like the third generation tests arent reliable until about 3 months after exposure to the virus.
What Happens When You Go For A Test
Normally, testing involves taking a small sample of blood from your finger or your arm, or an oral swab. This is where you rub the testing pen along your gums to collect cells from your mouth.
How long it takes for HIV test results to come back will depend on the type of test you are taking. If youre taking a rapid test, you will be given your results within 20 minutes. Other types of tests will be sent to a laboratory and it may take between a few days and a few weeks for you to receive a final result.
Tests these days are very reliable, but if your result comes back positive, you should have a second confirmatory test to double check your result. If this is also positive, you will get an HIV diagnosis, after which you can start treatment.
Remember, HIV treatment these days is very effective and people with HIV can live long and healthy lives just like anyone else.

What Are The Different Types Of Hiv Testing
There are three main types of HIV tests: antibody tests, RNA tests, and a combination test that detects both antibodies and viral protein called p24 . All tests are designed to detect HIV-1, which is the type of HIV in the United States. Some antibody tests and the combination test can also detect HIV-2 infections, which are usually limited to West Africa. No test is perfect; tests may be falsely positive or falsely negative or impossible to interpret .
Positive test results are reportable to the health department in all 50 states and include the patient’s name. This information is then reported to the CDC so that the epidemiology and infection spread rates can be monitored. The names sent to the state remain confidential and will not be reported to employers, family members, or other such people. Some states allow anonymous testing in which the patient’s name is not recorded.
HIV antibody tests: HIV possesses many unique proteins on its surface and inside the virus itself. When someone is infected with HIV, their body produces proteins designed to tag the virus for elimination by the immune system. These proteins are called antibodies, and they are directed against the unique proteins of HIV. Unfortunately, these HIV antibodies do not eliminate the virus, but their presence serves as a marker to show that someone is infected with HIV. HIV antibody tests are the most commonly used tests to determine if someone has HIV.
What Are The Symptoms Of Hiv Infection
Symptoms of the initial HIV infection can mimic those of influenza and other viral infections. The only reliable way to tell if someone is infected is to get tested. Many people with HIV do not experience symptoms for years after the initial infection or have symptoms that are very similar to symptoms of other illnesses. For more, see this CDC web page: HIV/AIDS Basics.

How Does The 4th Generation Hiv Test Work
The fourth generation test is different because its a combination test thats more advanced. It can detect both HIV antibodies and the p24 antigen, which is associated with HIV. Testing for p24 allows earlier detection and diagnosing of acute HIV infection.
For a fourth generation test, youll have a small sample of blood drawn from a vein with a needle. You might feel a small sting from the needle. It takes a few minutes to take the sample. Once the sample is collected, itll be tested in a lab.
Results are available in a few days or in some cases, a few weeks.
What The Findings Tell Us
From the point of view of specificity, the figures confirmed that the incidence of false positives remains extremely low, even with the earlier generation tests.
The figure only worsened when retesting bloods from the acute stage infections. Of the 58 samples tested, the 3rd generation rapid tests achieved a sensitivity of only 5.2 percent to 25.9 percent, meaning that the majority of such infections would be missed using these rapid, antibody-based tests.
Even the 4th generationDetermine rapid antigen/antibody test was able to identify only half of the acute infections;despite having an estimated sensitivity of 96.6 percent and specificity of 100 percent. According to the UCSF researchers, the Determine worked best during acute infection when the patient’s viral load was over 500,000.
Not surprisingly, the lab-based ARCHITECT combination antigen/antibody test performed best. With an estimated specificity of 99.1 percent and a specificity of 100 percent, the tests were able to identify nearly 90 percent of acute infections.
