By Chris Evans and John GeddesFor the first time, a blood test can tell you if you are HIV-negative.
It is now possible to confirm whether you have HIV-1, a virus that can lead to AIDS.
This is because the antibodies that make people infected with HIV-2, the virus that causes AIDS, can be made in the blood.
In a study published in the Journal of Infectious Diseases, researchers at the University of Cambridge found that antibodies to HIV-3 could be made by people who have HIV and the antibodies to the virus could be detected by blood tests.
This has the potential to make the difference between living with HIV and dying from it.
This new test was developed by Dr Andrew Aylward and his colleagues from the Department of Biology at the Department for Medical Research and Technology.
They were looking at a different way of analysing the blood of people who were HIV-infected.
Dr Aylright said:”The antibodies that are made by HIV-4 can be produced in the immune system by cells in the central nervous system, and when the immune response to a virus is triggered, the cells are able to secrete the antibody.
These antibodies are produced in response to an antigen that has already been detected in the body.””
This process allows the immune cells to recognise the antigen and produce the antibodies themselves, and then produce a second, more protective antibody.
This process is known as immunomodulation.”
This second antibody then helps the immune reaction to continue.
“We are using this system to understand the immune responses of HIV-6-infecting people to the HIV-related immune responses.”
“By measuring the immune reactions to the same antigen that was produced by HIV virus, we can predict the extent of HIV infection and, hopefully, offer a new treatment to the many people living with the disease.”
The scientists said this was the first study to examine antibodies to different strains of HIV, and it showed that the antibodies produced in HIV-8 people and HIV-7 people differed significantly from those produced in people with HIV.”HIV-8 is a very different strain of HIV to HIV 6- and HIV 7-infections,” Dr Aylroy said.
“It has a very high infection rate.”
But it’s also very different to people who are infected with the HIV strain that causes the disease of AIDS.
“So we have a way of measuring the antibody levels in people who aren’t infected with that strain of the virus.”
The researchers say we can identify individuals who have had the antibodies in their blood from a different strain and that will be the first step in identifying the people who might be at risk of developing HIV infection.
“The test, called HIV-T assay, is a highly sensitive test that allows you to see if you have antibodies to antibodies to a specific HIV strain, or if you may have antibodies that could be associated with HIV disease.
This test is sensitive enough to detect antibodies to more than one HIV strain.
Dr Andrew A. Aylwards and colleagues, who were first to describe the concept of HIV antibody production, have published a new paper in the journal Nature that shows that antibodies can be generated by people infected or infected with a different HIV strain than that that causes HIV disease, called a latent variant of HIV.
This means that the person is at risk for HIV infection if the latent variant is passed on from mother to child.
The researchers used an immunomimetic assay to test a group of people infected and HIV positive with a latent version of HIV and HIV negative with the virus from a latent strain of a different type of HIV virus.
This analysis showed that antibodies could be produced by people with the latent virus, or those infected with both HIV-like and HIV disease variants.
The findings indicate that there is a possibility that we may be able to use antibodies to detect HIV infection in people living without the virus, and this will help to identify people who need further treatment.
The results of this study will be published in a peer-reviewed journal.
Dr Ian Smith, Director of the University’s Centre for Infectious Disease Research, said: “These results have important implications for people living in the community and will provide vital information for those who have recently tested negative and are at risk.”
If you or someone you know has been diagnosed with HIV, this test can help to establish your status and provide you with the best possible treatment options.”
In a small, controlled trial, we have shown that it is possible to identify the people most at risk and offer them the best options to manage their HIV.
These results also give us hope that we will be able develop a vaccine that will protect against HIV-associated infections.
