What is the HIV test?
HIV tests, also known as HIV screening, are perhaps the only method to determine whether you possess the virus. Several testing methods use to examine your blood or even other bodily fluids to see if you are sick. Most people can’t spot HIV straight away since it takes longer for your system to produce antibodies and enough viruses to develop inside of oneself.
Importance of the HIV test
If you do have an infection, finding out rapidly means that you can begin medical care right away to feel good and enjoy a long, fulfilled life. It would help if you also took measures to prevent HIV from being passed on to other people. Pregnant women must screen because early diagnosis means you probably won’t carry it along to your kid.
What this test will do?
This HIV test will check whether your body has a virus or not. If you are infected the test will come positive and then you have to undergo the treatment.
Who’s going to have an HIV test?
The CDC suggests that everybody in the country within the age group of 13 and 64 should be screened for HIV at minimum once. You should be screened more often—at minimum once per year; you are at greater risk of being infected with HIV.
I have had a couple of intimate partners.
- Had unsafe sex with somebody who is or may be HIV-positive, even somebody whose sexual background you didn’t know.
- Injected medications with an injection, syringe, or other product that somebody else initially used.
- Have or are being screened for tuberculosis, HIV, or other sexually transmitted infection, including syphilis, herpes, chlamydia, or gonorrhea
- Have had sex regarding drugs or money
- I had sex with anyone who’s in the background of all of these.
What other kinds of tests performed, and when are they going to work?
- There are three types of tests accessible: nucleic acid (NAT) tests, antigen/antibody tests, and antibodies tests. HIV tests generally conduct on blood or vocal fluids. They can also do on the urine.
- The NAT is looking for the real virus in the body and involves taking blood from the veins. The test could either say whether an individual has HIV or just how much of the virus is detectable in the body (known as an HIV viral load test). Although NAT can diagnose HIV earlier than other forms of testing, this method is very costly. It is not commonly used for screening persons until they have had an elevated risk or potential exposure and have initial signs of HIV infection.
- The antigen/antibody test is the same for both HIV antigens and antibodies. Antibodies are developed by your innate immunity when you introduce to viruses such as HIV. Antigens are extrinsic factors that activate the immune function. If you do have HIV, an antibody called p24 is released before antibodies grow. Antigen/antibody tests are required for laboratory tests and have become popular in the United States. Such a laboratory procedure involves extracting blood from the patient. Also, there is a simple antigen/antibody test accessible that perform with a finger pinch.
- HIV antibody checks only check for HIV inhibitors in your bloodstream or oral fluid. Blood tests using blood from the patient will detect HIV earlier than blood tests via a finger pinch or oral juice during infection. Most of the quick tests and that the HIV self generally recognized are antibody testing.
A NAT is used by taking particular primers for HIV-1 so as to know the RNA under the sample of reactive multiplex NAT which can have HCV RNA or HIV-1 RNA depends on the assay. Doing a NAT test depends on step for those which take into consideration the multiplex tests not detecting the discriminate HIV RNA and HCV RNA.
Multiplex NAT: which is used to identify the HCV RNA and HIV-1 RNA?
Single Virus NAT: which used to identify the HCV RNA or HIV-1 RNA.
HIV 1 & 2 Antigen methods
This test starts with the antibody identification and the HIV-1/-2 antigen through the chemiluminescence immunoassay. When the outcome is reactive, after that the HIV-1/-2 antibody differentiation test through immunochromatographic method will be done.
How long is it going to take to achieve results?
- Laboratory studies (NATand antigen/antibody) demand that blood extracted from the veins into a pipe and then the sample submit to the laboratories for processing. The findings may take a few days to be accessible.
- With a quick antibody screening test, generally performed with fingertip blood or vocal fluid, the results prepares in 30 mins or even less.
- The quick antigen/antibody analysis is performed with a finger pinch and requires 30 minutes or even less.
- The oral antigen fluid self-test returns around 20 minutes.
How early after I have exposed to HIV will a test detect whether I possess a virus?
No HIV test can diagnose HIV instantly after infection. When you believe you have been subjected to HIV over the last 72 hrs speak to your healthcare professional regarding post-exposure prophylaxis (PEP) straight away.
What reports will conclude?
When an individual may have subjected to HIV and where the test will tell if they possess the virus is considered the window period. The length of the window ranges from individual to individual and relies on the type of testing used to diagnose HIV. Contact your health care professional or evaluation counselor about the timeline for the testing you are taking.
- The nucleic acid test (NAT) will usually tell you whether you possess HIV infection Ten to three to four weeks after exposure.
- An antigen/antibody check conducted by a venous blood laboratory will typically detect HIV infections 18 – 40 hours after onset. Antigen/antibody checks performed with your fingertip blood can take much longer to diagnose HIV (18 to 90 days after exposure).
- Antibody tests could take between 23 and 90 days to diagnose HIV infection following exposure. Much of the rapid experiments and personality are antigen tests. In particular, blood tests using blood through a vein will detect HIV earlier than blood tests via a finger pinch or oral saliva after exposure.
When you got an HIV check after a possible exposure to HIV and the outcome is negative, get checked twice after the window duration. Know, you could only be sure that you will be HIV-negative unless:
- Your next recent test will be after the window era.
- And during the window era, you did not have a possible HIV exposure. If you have potential direction, you may need to recheck.
The difference of antibody among HIV-1 and HIV-2
A +ve HIV test doesn’t indicate that you possess AIDS, the most significant advanced infection phase. HIV medication will prevent you from having AIDS, so speak to a doctor about taking drugs named antiretroviral therapy (ART). These medications lower the level of the viruses in your body, often to a level where a test can’t identify it. They also strengthen your immune function so that your HIV does not become AIDS.
Adverse outcomes of the test
If your outcome is negative, you should take action to safeguard yourself against HIV. These include the practice of safe sex, including the use of medicines known as pre-exposure prophylaxis (PrEP). And if your results are negative, your spouse may still carry a virus. Speak to them regarding getting checked.
It might take as much time as seven months for someone like you to provide enough antibodies to produce a positive test outcome. Once you have contaminated for three months within about and your testing result is negative, take another testing at six months towards being sure.
