How Do They Check For Hiv

What Does The Test Involve

How To Know If You Have AIDS – Recognize HIV Symptoms

HIV testing within VA is voluntary and confidential. It is up to you to decide whether you want to be tested. Before deciding, you may request educational material on HIV and HIV testing. VA also encourages you to ask your provider any questions you may have.

If you give your consent to be tested, an HIV test will be done with a sample of blood or with fluid from inside your mouth. For the blood test, blood is drawn either from an arm or from a finger with a needlestick. For the oral-fluid test, a swab is used to brush the inside of your mouth. The type of test you can get depends on what is offered by your VA facility.

Traditional blood test results are available in a few days. Some facilities offer rapid tests that provide preliminary results in around 20 minutes. However, it is important to know that all patients who have positive results on the first test must be retested with a second test. If your test is performed on blood from a vein and the first result is positive , a second test will be done automatically to confirm the results. If your test is done using oral fluid or blood from a finger prick, and the result is positive , blood must be taken from a vein for a second test to confirm the results. An HIV result is considered truly positive only if two different tests are positive.

Where To Get Tested For Hiv

Getting an HIV test is easy. Tests for HIV and other STIs are confidential and available from your local doctor , or a sexual and reproductive health clinic.

It is a good idea to have some pre-test counselling. Before the test, talk with your doctor, nurse, or peer tester about any concerns, your level of risk, whether you are likely to be HIV-positive and what a positive result may mean.

How Soon After Exposure To Hiv Can An Hiv Test Detect If You Are Infected

No HIV test can detect HIV immediately after infection. If you think youve been exposed to HIV, in the last 72 hours, talk to your health care provider about post-exposure prophylaxis , right away.

The time between when a person gets HIV and when a test can accurately detect it is called the window period. The window period varies from person to person and also depends upon the type of HIV test.

White Blood Cell Count

White blood cells are a subset of cells produced in bone marrow whose primary role is to fight infection. A white blood cell count is one of the panel of tests included in the CBC that measures not only the total number of leukocytes but also the different types of white blood cells in a blood sample, namely:

Within the context of HIV, an elevated WBC typically means that your body is fighting an infection. Other tests can then be performed to pinpoint the cause.

An elevation of certain white blood cells may indicate a specific type of infection or an allergic inflammatory response. For example, higher than normal eosinophils may suggest a parasitic infection like toxoplasmosis, while elevated basophils can develop in people with a hypersensitive drug reaction.

A decrease in white blood cells may be the result of HIV medications , a minor viral infection, or a major opportunistic infection like tuberculosis.

CD4 T-cell lymphocytes are a type of white blood cell that HIV preferentially targets and infects. For this reason, they serve as the primary marker of your immune status if you have HIV.

How Often Do You Need To Get Tested For Hiv

Can Hiv Be Transmitted Through Blood Transfusions

How to Get Tested for HIV | STDs

Yes but this is very rare. In the unlikely event that a person who is HIV-positive donates blood products that are not tested, the person who receives the blood product is likely to develop an HIV infection too.

If youre thinking about donating blood but are not sure about your HIV status, you can request an HIV test in advance of donating at your local clinic.

In order to prevent this, international health regulations require all blood products, such as organs or tissues, to be screened for a number of viral or bacterial contaminations before they are used.

During the screening process any blood products which contain HIV, hepatitis B, hepatitis C, or syphilis will be disposed of.

This means that the transmission of HIV through blood products is very rare, but examples have occurred in some low-income countries which lack the equipment to test all blood.

  • 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.
