Accuracy

Hello
I know that none of the HIV tests are 100% accurate. Based on this have the following clarifications.

1. If none of the tests are accurate, how can anybody know whether the person is infected with HIV or not. Can it go undetected for ages until the person converts from HIV to AIDS.
2. If your test kit shows false negative, what are the odds that all subsequent tests taken via biosure is showing as false negative. This is asked to make sure whether we need to take some other company tests to see whether it gives different result or is it just odds. I am wondering if one company gives false negative, all subsequent tests done through that company will give same false negative. Please confirm.

3.If a person gets detected by HIV after a period or 1 year or 2 years,is it still possible for him to get antiretroviral treatment and expand his life expectancy?

Hi HIV and AIDS are different things. HIV is a virus that infects you. Over a very long time (10 years +) this virus causes damage to your immune system. At a certain point this damage leads to a syndrome which is known as AIDS. There is no specific test for AIDS. The condition is diagnosed by assessing the damage to your immune system. When that damage reaches a certain level then you have AIDS. The BioSURE HIV self test will detect HIV infections from 3 months to a number of years. We know at least 10years. I hope that this helps. Kind regards Gary

Thanks Gary for the wonderful replies. I just have one last question. 1. Does the detection of HIV or AIDS is same or different? If a person taking your test is in advanced stage of AIDS, will it still detect antibodies or we should go for a different test alltogether for AIDS. Reason asking is that if a person shows negative for HIV but postive for AIDS, will your test device shows as negative or postive.

Hi ConfusedMan Sorry for not having responded sooner. My answers to your questions are as follows: 1. Whilst it is true to say that no HIV test is 100% accurate the ones are allowed to be used in the UK via CE marking, such as the BioSURE HIV Self Test, are extremely accurate at detecting HIV when it is present. But because our test relies on antibodies to HIV you need wait 3 months after exposure for a negative result to be conclusive. Our extensive studies have shown that at least 997 in every 1,000 HIV positive people will correctly test positive using the test. It takes about 10 years for HIV infection to cause AIDS. Pretty much the only way for someone to go undetected is not testing. 2. The odds are the same around 3 in 1000. False negative test results of multiple tests are independent of the previous test. So if you take 2 tests for the same exposure the odds of both being wrong are about 1 in 100,000. 3. Yes absolutely. ARV treatment has significant benefits up until about 5 years post infection. I hope that this helps to answer your questions. Kind regards Gary Carpenter BioSure (UK) Limited
